If you already own a CNC table, the plasma cutter you hang on it decides how much material you can cut cleanly, how fast the Z axis can move without crashing, and whether your controller stays stable at the same time. Plenty of handheld machines advertise CNC compatibility and then turn out to have no way to fire the torch or report arc voltage back to the height controller. That gap is what separates a machine that works on a gantry from one that frustrates you within a week.
We spent several weeks reading spec sheets, owner reviews across r/plasmacutting and PlasmaSpider threads, and service complaints for every CNC-capable power supply we could find, then sorted them by the three things that matter on a table: a real machine torch interface, arc voltage output for torch height control, and a blowback pilot arc that does not spray high-frequency noise across your controller board. Every machine in this list of the best plasma cutters for CNC tables meets at least two of those three, and we say plainly which ones fall short.
We also cover the boring parts that decide whether a table runs smoothly: compressor sizing in SCFM and PSI, pierce height versus cut height, and the consumable economics nobody quotes in a marketing listing. If you are still choosing a table rather than a cutter, our guides to the best plasma cutters overall and the best plasma cutters for home shops cover the handheld side of the market.

1. SILATU 85A CNC Plasma Cutter – Most Verified CNC Ports
SILATU 85A CNC Plasma Cutter Machine, Non-HF Blowback Pilot Arc, 110V/220V
85A at 220V and 40A at 110V
Auto voltage detection
60 percent duty cycle
70 PSI at 250 L per min
Pros
- Blowback non-HF start keeps table electronics stable
- Dual 110V and 220V with automatic voltage detection
- Digital readout shows pressure voltage and current
- 2T/4T plus mesh mode with 3-15s post-flow
- 16FT torch and 10FT ground clamp included
Cons
- Manual quality is poor for first-time owners
- Straight CNC torch sold separately
- Output drops noticeably on 110V
This is the machine I kept coming back to while comparing interfaces. It has the two CNC connectors we look for, a 2-pin arc voltage output at a 1:1 ratio and a 5-pin signal control port, and a blowback non-HF pilot arc that the manufacturer states is compatible with CNC systems while minimizing high-frequency interference. At 267 reviews it also carries the largest owner history of anything in this roundup, which matters when you are wiring a torch to a moving gantry.
Owners consistently praise clean, fast cuts on mild steel and a non-touch arc that starts on painted and rusted stock without a scratch start. Seventy-two percent of ratings sit at five stars, and the digital display showing pressure, voltage and current makes setup on a new table much less guesswork.
The specification that convinced me is the dual-voltage spread. It cuts up to 15mm at 40A on 110V and up to 35mm at 85A on 220V, which covers thin plate on a garage circuit and heavy steel in the shop from one machine. Air requirement is about 70 PSI at 250 L per minute, and the compressor is sold separately.
On the air side, the rear-mounted filter with a quick-connect 1/4 NPT fitting is a detail that saves setup time, and the integrated air sensor mirrors pressure on the front panel. Trigger functions cover PT, 2T, 4T and PA with post-flow adjustable from 3 to 15 seconds plus a dedicated mesh cutting mode, which is what you need for expanded metal and grating rather than solid plate.
How it behaves on a real table
The 1:1 arc voltage divider means most THC boards read it without a scaling resistor, which removes one of the most common wiring headaches on budget machines. That pairing, plus a blowback start, is why we rate it first, even though most of the inverters here carry lower amperage figures.
The honest limitation is documentation. New owners report vague instructions, so budget an evening with the manual, a multimeter and the connector pinout before your first automated job rather than assuming the table will just fire the torch.
Where it falls short
The straight CNC torch is a separate accessory, not included, so plan that into the cost before you wire it to a gantry. The handheld torch can be mounted on a CNC system, but owners running long table jobs will want a proper straight torch for consistent arc length at height.
Output also drops noticeably on 110V compared with 220V. If your shop has 220V available, use it, and if you are on a 20A garage circuit the 40A figure is your realistic ceiling.
2. Everlast PowerPlasma 52i – Built-In CNC Port on a Small Footprint
PowerPlasma 52i 50Amp Plasma Cutter, CNC Compatible, High-Performance Cutting for Metal, 220V, Professional Quality
50A inverter with full CNC port
iPT60 Italian torch
Post-flow and pilot arc tip saver
Pros
- Full CNC port with blowback pilot arc that will not disrupt table electronics
- Genuine Tecmo iPT60 torch rather than a knock-off
- Owners report clean cuts up to 3/8 inch
- Generator friendly under 5 percent total harmonic distortion
- Responsive technical support
Cons
- Consumables cost more than aftermarket alternatives
- Ground clamp and cable quality are basic
- Instructions are limited
The 52i is the machine we would put on a 4×4 hobby table where floor space matters. It has a full CNC port built into the chassis rather than an adapter kit, a blowback pilot arc that forum owners specifically praise for not disturbing their table electronics, and a genuine Italian-designed Tecmo iPT60 torch that does not need replacing out of the gate.
With 26 reviews averaging 4.6 stars and 72 percent at five stars, the owner base is small but unusually loyal, and most of them bought it specifically for table work. Owners report cutting up to 3/8 inch cleanly and quickly, and one repeatedly praises the interface as straightforward despite the limited instructions.
The pilot arc tip saver limits the pilot arc to 3 seconds with a continuous mode available, and the adjustable post-flow timer extends consumable and torch life. Large digital displays for amps, air pressure and post-flow mean you can dial in parameters without guessing at a knob.
Why the CNC port matters here
A full CNC port means the firing signal and the arc voltage path are part of the machine design rather than an add-on, so wiring a THC board is straightforward. The blowback start also keeps high-frequency noise off your controller, which is the failure we see most often on cheap inverters.
It is also generator friendly under 5 percent total harmonic distortion, so it will run on a clean 8500W unit when the shop circuit is not an option. For a table owner cutting mild steel on a weekend, that flexibility is worth more than raw amperage.
Where it falls short
Consumable cost is the repeated complaint. Genuine Tecmo torch parts cost more than aftermarket copies, and while the originals last longer, a shop cutting daily will feel it in consumable spending.
At 50A this is not a heavy plate machine. Owners consistently describe 3/8 inch as the practical limit, and the ground clamp and cable quality are also mentioned as improvable. Some owners have reported durability and warranty service issues, which is worth weighing against the small review base.
3. LOTOS Supreme LTP7500CNC – Factory THC Output for 1 Inch Steel
Lotos Supreme LTP7500CNC Non-Touch Pilot Arc CNC Enabled Digital Plasma Cutter, Support THC Torch Height, 220~250V, 1 inch Clean Cut, Brown
20-75A DC output
Pre-installed CNC interface with THC output
220-250V on a 50A breaker
Pros
- Pre-installed CNC interface with THC signal output
- non-HF blowback start eliminates interference
- 14ft non-HF torch with central connector for fast hookup
- Pre-installed NPT 1/4 inch plug and air filter regulator
- Responsive service department
Cons
- Listing cut claims exceed the manual 60 percent duty cycle rating
- Consumables deplete quickly on sustained cuts
- Output droops on thicker plate
This is one of the few machines in the roundup that comes with the CNC interface and the THC signal output already wired, rather than relying on you to identify which connector does what. The torch height control output is pre-installed, the start is non-HF blowback so it will not interfere with a CNC computer, and the 14ft torch uses a central connector for fast hookup.
Output runs 20 to 75A DC with a 1 inch ideal clean cut and 1.5 inch maximum severance on 220/240V. The air requirement is 80 PSI at 4.5 SCFM on a 50A breaker, and the pre-installed NPT 1/4 inch plug plus air filter regulator make the air hookup a one-job task rather than an afternoon.
At 40.8 pounds it is portable but not light, and the packaging is 24 x 17 x 14 inches. It handles stainless steel, alloy steel, mild steel, copper and aluminum, which covers most table work.
Reading the cut capacity honestly
The important detail is the gap between the listing and the manual. Listings advertise a 1 inch clean cut, but the manual states a 60 percent duty cycle at 75A with a 7/8 inch feed rating, and owners describe the realistic envelope as 3/8 to 1/2 inch.
Treat the 1 inch number as severance territory and plan your table work around half inch. That is still plenty for a hobby 4×4 or 4×8 table cutting signs, brackets and plate work, but it is not the machine for production heavy plate.
Where it falls short
Two reviewers focused on the overstated 1 inch claim and on consumable wear under sustained cuts. Output also droops and blows back into the torch on thicker plate, which is the classic symptom of running at the edge of the rating.
With only 12 reviews, the long-term track record is thin. The service department is described as responsive and helpful, which partly offsets that.
4. ANDELI 65A CNC-Enabled – CNC Ports in the Box
ANDELI 65 Amp Plasma Cutter [CNC Enabled][ Non-HF],1.06″ Max Cut
65A non-HF output
1-1/16 inch cut at 220V
CNC connector kit included
4.05 inch LED display
Pros
- CNC ports and wire connectors are in the box
- Tool-free 110V and 220V switching for a home shop
- Large multi-zone LED display with fault error codes
- Non-touch pilot arc starts on stainless and aluminum
- Generous consumable kit with three electrodes and five nozzles
Cons
- Only 10 reviews so durability is largely unproven
- ECO mode reduces output power for demanding work
- Air regulator is manual only
Most budget inverters make you source the CNC wiring connectors separately. This one includes the 2-pin arc voltage and 4-pin signal control connectors in the package, so a new table owner can wire it up on day one without a second order. It also runs 65A non-HF with a 1-1/16 inch cut at 220V and 3/5 inch at 110V, punching 5/16 inch at 220V.
The 4.05 inch LED interface is oversized for the class, with three dedicated zones for PSI, voltage and current plus fault error codes. That display is more useful on a gantry than on a bench, because you can check air pressure and current without walking over to the machine.
![ANDELI 65 Amp Plasma Cutter [CNC Enabled][ Non-HF],1.06](https://siemens-mobile.com/wp-content/uploads/2026/10/B0FJFDCHTC_customer_1.jpg)
Tool-free 110V/220V switching with a free power adapter and an IGBT inverter make it usable from a home shop circuit, and the ECO mode delivers 100 percent continuous cutting at 60 percent output power for thin material. The FPT60 13FT torch, three electrodes and five nozzles are in the box.
Why this one earns a spot on a CNC table
A 4-pin signal control port rather than the more common 5-pin is the one wiring difference to plan for. It is a straightforward two-wire change on most THC boards, but check the pinout before your first run.
Non-touch pilot arc starts reliably on stainless, aluminum and carbon steel, and the 2T/4T modes with intelligent post-blow mean the controller can fire the arc without a manual trigger. That combination is rare at this level.
Where it falls short
Ten reviews is too small a sample to judge long-term durability, and 8 percent of ratings land at three stars, which hints at occasional inconsistency. The ECO mode reduces output power, so switch it off for plate work.
It also runs at 26.9 pounds with a 23 x 15.5 x 13.5 inch package, so it is not a small machine despite the budget position. Air adjustment is manual only, which is fine if you set it once and leave it.
5. Bestarc 50A Non-HF – Best Reviewed Starter Cutter
Bestarc 50A Non-HF CNC Plasma Cutter, Blow Back Pilot Arc, Large LED
50A inverter at 20.6 pounds
5/8 inch clean cut at 110V
1 inch at 220V
65 PSI at 250 L per min
Pros
- Blowback non-HF start is CNC friendly and cuts interference
- Light at 20.6 pounds for a 50A inverter
- LED display with fault error codes simplifies troubleshooting
- 2-pin and 5-pin CNC connectors built in
- Clean cuts on iron steel aluminum and copper
Cons
- Air compressor sold separately
- 110V output is much weaker than 220V for thicker material
- Air pressure adjusted manually only
With 84 reviews averaging 4.3 stars, this machine has a large owner base, and the data behind it is not thin. Seventy-two percent are five star, and the feedback centers on clean cutting across common metals, light weight and CNC port availability.
It has the two connectors we look for, a 2-pin arc voltage output at a 1:1 ratio and a 5-pin signal control connector, both built into the chassis. The blowback non-HF pilot arc with CNC capability prevents high-frequency signal interference, which is the specific failure we were trying to avoid.
Cut capacity is 5/8 inch at 35A on 110V and 1 inch at 50A on 220V. Recommended air is 65 PSI at 250 L per minute, and the LED screen shows air pressure, voltage and current with fault error codes. Trigger functions cover 2T, 4T, PA and PT with post-flow from 3 to 15 seconds and pilot arc timing up to 15 seconds for mesh cutting.
What 20.6 pounds buys you
This is a light machine for a 50A inverter, and weight matters more on a table than people expect. At 20.6 pounds you can lift it onto a cart without a second person, which makes moving between a hobby bench and a shop bay simple.
The recommended breakers are 40A at 110V and 50A at 220V, so it fits a standard 20A branch circuit on the 110V side for thin work. Dimensionally it is compact at 6.14 x 11.2 x 13.62 inches.
Where it falls short
The 11 percent one-star share is tied mainly to compressor and voltage expectations, not cut quality. Buyers who planned on using a small pancake compressor are the ones who return it.
Output on 110V is noticeably weaker than on 220V for thicker material, and air pressure can only be adjusted manually. Plan on a dedicated compressor with a regulator and a moisture separator if you take this machine seriously.
6. LOTOS Apex LTP6300DCNC – Drag-Cut Torch With THC and ARC OK Outputs
LOTOS Apex LTP6300DCNC 63A CNC Drag-Cut Blowback Plasma Cutter 110V/220V
63A output with drag-cut control
Rear THC and ARC OK outputs
70 PSI at about 4.0 SCFM
Pros
- Rear THC and ARC OK outputs make automation straightforward
- Non-HF blowback start protects CNC control computers
- Owners report clean cuts on DIY tables with minimal post-grind
- Drag-cut torch removes standoff fatigue during layout
- Compact 21.5 pound unit with a well-written manual
Cons
- Machine torch not offered with this package and costly elsewhere
- Only a 0.9mm tip is included for a 63A machine
- Replacement tips are expensive for their size
The rear port on this machine is unusually explicit. It outputs high-precision torch height control signals and ARC OK signals separately, which is exactly what a THC board and a controller look for. You do not have to infer what a multi-pin connector is doing.
Output is 63A with a 3/4 inch clean cut and 1 inch severance, and the non-HF blowback pilot arc ignition is specified for low EMI to protect CNC computers. Automatic sensing covers 110/120V and 220/240V, with a 50A breaker at 120V and 40A at 240V, and air demand is 70 PSI at roughly 4.0 SCFM.
The drag-cut capability is the feature owners mention most warmly. The torch tip can rest on sheet metal for hand tracing, which removes the hand fatigue of holding standoff on long layouts and makes marking and fitting templates far more comfortable.
It is also compact at 21.5 pounds and the package is 17.6 x 13.5 x 12.2 inches, with an 18ft blowback cutting torch, two nozzles, two electrodes, 2-pin and 5-pin CNC connectors and a 6ft ground cable included. Owners running this on a DIY CNC report very clean cuts with minimal post-grind cleanup.
It is optimized for LOTOS DC6309 drag and NCON series replacement parts, so consumable sourcing is straightforward if you stay within that family.
Why ARC OK matters for automation
An ARC OK signal tells the controller the arc has actually established rather than just that the firing command was sent. That distinction matters when a pierce fails, because the machine can stop instead of dragging an unlit torch across the plate and marking it.
Combined with the rear THC output, this is one of the cleanest factory interfaces in the roundup. For a table that runs long unattended jobs, that is worth more than a headline amperage number.
Where it falls short
The machine torch is not offered with this package and commands a premium when sourced elsewhere, which is a real gap for anyone running this as their primary table cutter. Check that cost against a machine that includes the torch.
Only a 0.9mm tip is included, and a 1.0 or 1.1mm tip is needed to reach the full 63A rating. Replacement tips are also expensive for their size. The manual largely covers a different model and stops short of full 63A cut charts.
7. Everlast PowerPlasma 82i – Heavy Plate With a Machine Torch Included
PowerPlasma 82i 80 Amp CNC Plasma Cutter with PTM-80 CNC/Machine Torch with 24 ft. cable and Euro quick-connect central connector
80A IGBT inverter at 60 percent duty cycle
Blowback IPT-80M machine torch
24ft Euro quick-connect cable
Pros
- Includes blowback IPT-80M machine torch and 24ft cable
- Quality cuts in 1 inch AR-500 wear plate with minimal dross
- Owners report clean results at 200-400 mm per min on GRBL tables
- Post-flow adjustable up to 50 seconds protects consumables
- Five year parts and labor warranty
Cons
- Supplied machine torch burned out quickly for one owner
- Fine cut small kerf consumables are hard to find
- Support and warranty fulfillment described as unresponsive
This is the machine we would trust with wear plate and thick structural steel. It includes the blowback IPT-80M machine torch with a 24ft cable and Euro quick-connect central connector, the part most owners end up sourcing separately. On a gantry, that connector means the torch can be removed for consumable changes without rewiring.
The 80A inverter output runs at a 60 percent duty cycle using Infineon IGBT modules, and the spec sheet calls for regularly cutting up to 1 inch with quality cuts in 1-1/4 inch steel at 10-12 IPM. Owners report clean results at 200-400 mm per minute on home GRBL CNC plasma tables, and one reports cutting 1 inch AR-500 wear plate with minimal dross.
Adjustable post-flow runs up to 50 seconds, a longer cooling window than the 3 to 15 second ranges on most of the budget machines here, and that matters on long cuts through thick plate where the cup needs cooling time after the arc stops. A built-in 3-second pilot arc tip saver reduces consumable wear during idle time.
Where it earns its place
Having the machine torch in the box is the deciding factor. Most machines in this roundup treat the torch as an accessory, and sourcing a compatible one is a common early frustration for table owners.
The five year parts and labor warranty matches the 62i and runs longer than anything else here. For a shop cutting daily, warranty length is a reasonable proxy for how long the manufacturer expects the inverter to last.
Where it falls short
Fine cut and small kerf consumables for this torch are hard to source, which makes thin sheet metal and detailed sign work harder at high resolution. One owner also reported the supplied iPTM-80 machine torch burned out quickly and was replaced with an aftermarket PTM-100.
Customer support and warranty fulfillment were described as unresponsive by one owner, and another reported a bad solenoid out of the box plus a cracked face plate. At 53 pounds it is a two-person move, and with 10 reviews the track record is thin.
8. Everlast PowerPlasma 62i – Straightforward 60A Table Workhorse
PowerPlasma 62i 60 Amp CNC compatible plasma cutter
60A inverter at 60 percent duty cycle
Blowback IPT-60 non-touch torch
3/4 inch regular cut
Pros
- CNC compatible with cleaner more precise cuts than a handheld
- Owners cut reliably from 16 gauge up to 5/8 inch
- IGBT Infineon modules and solid construction
- Five year warranty with responsive service
- Adjustable post-flow timer with digital display
Cons
- 60A is thin for CNC work on thicker material
- Ground lead is very short
- One owner reported a failure shortly after purchase
The 62i sits at the amperage most table owners actually reach for. It regularly cuts 3/4 inch with 1-1/4 inch maximum severance, at a 60 percent duty cycle with IGBT Infineon modules, and it carries the same five year parts and labor warranty as the 82i.
Owners running it on CNC machines specifically like the cut quality and report more aesthetically pleasing, precise results than they got from a handheld. They also describe handling everything from 16 gauge up to 5/8 inch reliably, which is the range most sign, bracket and plate work sits in.
The blowback IPT-60 plasma torch gives a non-touch pilot arc for dirty, painted or rusted metals, and a 3-second pilot arc tip saver shuts the pilot arc down when no cutting is present. It works with 11000W clean power generators, which helps on job sites.
Why 60A is the sweet spot
Forum owners running CNC plasma tables frequently name 14 gauge cold roll steel as the ideal material, and 60A covers that range with plenty of headroom for 3/8 and 1/2 inch plate. It is the amperage tier that matches a 4×8 hobby table without pushing a compressor or a circuit past its limit.
Owners also mention responsive customer service and solid construction, which is more than several competitors in this price tier can say.
Where it falls short
The most common regret is amperage. Several owners say 60A is the limit for table work and wish they had bought a higher amp model, so if your material runs past 5/8 inch regularly, step up to the 82i.
The ground lead is very short, and one owner reported the machine stopped working shortly after purchase with no customer service response. With 20 reviews the sample is still small.
9. Bestarc 80A IGBT – Straight CNC Torch Included in the Box
Bestarc CNC Plasma Cutter Machine, 80A IGBT 110V/220V Blow Back Pilot Arc
80A IGBT inverter at 110V and 220V
Straight CNC torch included
1.57 inch max cut at 220V
Pros
- One of the few machines that includes a straight CNC torch
- 2-pin arc voltage plus 5-pin CNC interface
- Non-HF blowback start avoids controller interference
- Quick-connect 1/4 NPT air inlet gets you cutting quickly
- Generous cut capability at 220V
Cons
- Only 7 reviews so reliability is essentially untested
- 25 percent one-star share in the small sample
- Air pressure cannot be adjusted automatically
Including the torch is what separates this machine. It is configured with a straight plasma torch specifically for CNC table use, and most competitors make that a separate purchase. On a table, a straight torch holds arc length more consistently at height than a bent handheld torch, which reduces dross on long cuts.
The interface is a 2-pin arc voltage output at a 1:1 ratio plus a 5-pin CNC interface, and the non-HF blowback non-touch pilot arc is specified to prevent interference with CNC controllers. Cut capacity is 5/8 inch clean at 110V and 1.57 inch max cut at 220V.
Air handling is a built-in air sensor with a manual regulator and a quick-connect 1/4 inch NPT inlet running at 70 PSI and 250 L per minute. Recommended breakers are 60A at 110V and 50A at 220V, and trigger functions cover 2T, 4T, PA and PT with 3-15s post-flow and pilot arc timing up to 15 seconds.
Why the bundled torch changes the math
For a first CNC plasma table, the torch is the part most people underestimate. Having a straight torch in the box removes a sourcing problem, a compatibility question and one more variable when a cut will not stay consistent.
The LED screen shows air pressure, voltage and current with fault error codes, which makes diagnosing a poor cut on a new table much faster than guessing at settings.
Where it falls short
This is a very new listing with only seven reviews, so reliability is essentially untested. A 25 percent one-star share in that small sample signals some of the usual settling issues on a first production run.
At 34.8 pounds it is a substantial machine, and air pressure cannot be adjusted automatically. The compressor is sold separately and 250 L per minute is a real demand, not a suggestion.
10. HITBOX HBC65 – Compact Setup With Air Cutoff Protection
HITBOX Plasma Cutter Machine, 65A 110V/220V DC Inverter IGBT, Non-HF Non-Touch Pilot Arc, Max 1″ Cut, Mesh Cutting, 2T/4T, Post-Flow, Large Digital Display, CNC Ready, Air Sensor, 60% Duty Cycle
65A dual voltage
5/8 inch clean cut at 220V
Pilot arc tunable to 3-5s for CNC
60 percent duty cycle
Pros
- CNC-ready design with non-HF start limiting electronic interference
- Pilot arc timing can be shortened for CNC runs to save consumables
- Air monitoring stops cutting below 30 PSI to protect cups
- Quiet operation since the fan runs only when needed
- Compact and easy to move between shops
Cons
- 3.8 average across only 9 reviews
- 30 percent one-star share in that small sample
- Needs at least 80 PSI and 6.36 CFM of air
- CNC integration described as ready rather than shipping with a machine torch
This is a compact machine that moves easily between a garage and a shared shop bay. The feature set is competitive for the class: non-touch pilot arc with a non-HF start, adjustable pilot arc duration from 3 to 15 seconds with 5-10 seconds recommended for manual work and 3-5 seconds for CNC, and a 60 percent duty cycle. The listing puts the unit at under 14 pounds, so it is easy to load and unload.
That CNC-specific pilot arc timing matters more than it sounds. A shorter pilot arc burns less consumable and gives the controller a cleaner signal to work with, and the manufacturer documents the CNC range separately from the manual range.
Cut capacity is a 5/16 inch clean cut and 5/8 inch max on 110V, rising to a 5/8 inch clean cut and 1 inch max on 220V. The digital air monitoring alerts on high pressure and stops cutting below 30 PSI, which protects consumables when a compressor runs down.
Why it stays on the list
The air cutoff is a genuinely good feature for a CNC table, where a job can run long and a compressor tank can drop below working pressure without anyone standing next to it. Cutting off before the pressure falls protects the cup and electrode.
Intelligent fan control means the fan runs only during cutting or above 40C internal temperature, so the machine is quiet between cuts, which is pleasant on a hobby table in a shared room.
Where it falls short
This is the weakest showing in the roundup, with a 3.8 average and a 30 percent one-star share across nine reviews. The feature set is competitive, but the track record is not.
Air demand is the real constraint here: the listing calls for at least 80 PSI and 6.36 CFM, with a recommended working range of 50-60 PSI. CNC integration is described as ready rather than including a dedicated machine torch, and consumables are excluded from the 2-year service.
How to Choose a Plasma Cutter for a CNC Table in 7 Steps
Before you compare amperage, work through this list. It is the fastest way to rule out a machine that cannot do what you need.
Confirm a machine torch interface. Look for a 2-pin arc voltage output plus a signal control port, which is 5-pin on most machines here and 4-pin on the ANDELI. A handheld torch alone is not enough.
Check for arc voltage output at a usable ratio. A 1:1 output reads directly on most THC boards. If the spec is silent, ask before you buy, because an uncalibrated signal can make the Z axis hunt.
Reject high-frequency start. Blowback pilot arc only. HF start bursts can disturb stepper drivers, USB cables and contactor wiring on the gantry.
Match amperage to real material. 30-50A covers sheet and thin plate, 60-80A covers plate and structural work, and 85A plus is production territory. Ignore the max severance number when choosing.
Verify trigger modes and post-flow. You want 2T or 4T so the controller can fire the arc, and adjustable post-flow of at least a few seconds to protect the cup.
Size the air supply before the machine. Every model here needs a compressor that is not in the box. Take the SCFM figure and build your tank size around it.
Check consumable availability for the torch. A machine whose consumables cannot be sourced is not cheaper. Stay within the documented torch families.
The four-tier framework for cut thickness is worth internalizing, because it is the fastest way to see why listings disagree. Rated thickness is what the marketing claims. Recommended thickness is where the manufacturer guarantees performance. Clean cut thickness is what you can cut without dross at a sensible travel speed. Severance thickness is where the arc blows through and the kerf looks terrible. Across this roundup, 3/4 inch sits at the edge of what most machines cut cleanly, and only the 82i and the LOTOS Supreme are specified for regular 1 inch work.
Air Supply: Sizing a Compressor and the Filtration You Need
Undersized air is the most common cause of erratic arcs, dross-heavy cuts and premature consumable failure on a CNC plasma table, and pancake compressors are the usual culprit.
Air demand varies across this roundup, so read the figure for the machine you are actually buying. The SILATU 85A and both Bestarc machines call for about 250 L per minute at 65 to 70 PSI, the LOTOS Apex needs roughly 4.0 SCFM at 70 PSI, the LOTOS Supreme asks for 4.5 SCFM at 80 PSI, and the HITBOX is listed at 6.36 CFM with a minimum of 80 PSI.
Multiply the flow figure by the duty cycle, add margin, and size the receiver so pressure does not sag mid-cut. Sagging pressure shows up as an arc that cuts cleanly for the first few inches and then starts laying down dross.
Filtration is not optional on a CNC installation. Run a coalescing filter and an auto-drain moisture separator between the compressor and the machine, because a single droplet of water or oil in the air line pits the nozzle, weakens the pilot arc and triggers torch height control errors that look like a controller fault.
Use a dedicated air line with a regulator set at the machine, not a shop manifold shared with an air tool. A slingshot from a framing nailer in the same room is enough to make a pierce fail.
Pierce Height vs Cut Height: Starting Values That Work
Pierce height is how far the torch sits above the plate at the moment the arc strikes, and cut height is the standoff it holds while moving. They are not the same number, and confusing them is the most common cause of failed pierces.
The consensus approach is to pierce at roughly 1.5 to 2 times your cut height so the plasma column clears the kerf as it opens instead of blowing back down through the hole. A Hypertherm owner running a table cites a pierce height of .120 inch as their working reference point, which tells you how far apart the two values sit.
A practical starting sequence: set pierce height at about 0.10 to 0.15 inch for thin material like 16 gauge, then drop to about 0.03 to 0.06 inch for the cut itself. For 1/4 inch and thicker plate, pierce closer to 0.20 inch and cut around 0.06 inch. Users calibrate by material, amps and travel speed together, so treat these as starting values rather than constants.
On a 30A machine cutting 16 gauge at 112 IPM, the pierce height question comes up constantly in forums, which tells you the answer is genuinely material specific. Pierce in the middle of the part where overcut does not matter, because the first attempt is often taller than you think.
Torch Height Control and CNC Controller Pairing
Torch height control is the biggest frustration table owners report, because a torch that never holds a consistent height produces dross and failed pierces. The mechanism is simple: the CNC controller sends a firing signal, the arc strikes, the THC board reads the arc voltage, and the Z axis moves up or down to hold a constant distance from the workpiece.
Choose a THC board that matches your controller firmware. Proma, LS-THC and Fusion are the common hardware options, and FluidNC, Mach3 and LinuxCNC are the firmware options. The firmware matters more than people expect, because each has a different way of handling the pierce-then-lower sequence.
The setup order we recommend: fire the arc manually at the pierce height, confirm the arc voltage reading is stable, set the THC up-slope and down-slope rates, then wire the machine torch connector and test a single 2 inch cut before running a program. Budget a weekend the first time.
Consumables and the True Cost of Ownership
Consumable cost is a hidden expense on budget machines, and it is the main reason forum owners tell new buyers to save up for a better power supply. Cheap tips burn through fast, and off-brand tips fitted to a quality torch can degrade performance badly enough to cost more in rework than they save on parts.
Consumables are not interchangeable in general. The LOTOS Apex is optimized for DC6309 drag and NCON series parts, the Everlast machines use genuine Tecmo iPT60 and iPT80 families, and the budget inverters use PT31 and PT60 style torches. Within one torch family the tip sizes are interchangeable, but across brands they are not, and a mismatched electrode and nozzle pair causes arc instability that looks like a power supply fault.
This is also why Is Hypertherm worth the money comes up so often. The forum consensus treats Hypertherm as the benchmark power supply and the standard advice is to use their settings, which reflects confidence that the consumable and parameter ecosystem is predictable. Total cost of ownership favors the machines with longer consumable life even when the purchase is higher.
Budget a spare kit of electrodes and nozzles for whichever torch you buy, and replace the electrode when you see arc wander rather than waiting for it to fail mid-job.
Water Table, Fume Extraction and Shop Safety
A CNC plasma table running in a home shop needs a fume extraction plan. Plasma cutting stainless steel produces hexavalent chromium fume, which is a serious respiratory hazard, and moving the arc outside does not contain it.
A water table or slat table serves two purposes: it cools the underside of the plate and the slats, which extends consumable life and cuts noise, and it helps suppress fume and spatter. Depth is a preference rather than a rule, with a few inches of water being typical for most hobby tables, so long as the torch clearance still allows your thickest material.
On eyewear, shade 5 is not enough on its own for plasma cutting. Most plasma arcs warrant shade 9 to shade 13 lenses, and the correct shade depends on your amperage, so check the lens rating chart rather than assuming. Use an ANSI Z87.1 rated auto-darkening helmet and wear the same shade whenever you are near the table, because the arc light off a reflective slat table is genuinely bright.

Frequently Asked Questions
What plasma cutters have a CNC port?
A CNC port is the machine torch interface, usually a 2-pin arc voltage output plus a signal control connector for firing the torch. The Everlast PowerPlasma 52i and 62i have a full CNC port built into the chassis. The SILATU 85A, Bestarc 50A, Bestarc 80A and LOTOS Apex LTP6300DCNC use 2-pin arc voltage with 5-pin signal control, the ANDELI 65A uses a 4-pin signal port, and the LOTOS Supreme LTP7500CNC ships with a pre-installed CNC interface plus THC signal output.
How many amps is a good plasma cutter for a CNC table?
For a hobby CNC table cutting 14 gauge mild steel and thin plate, 40 to 60 amps is the practical range. Small shops cutting structural work and up to 3/4 inch plate want 60 to 80 amps. Production shops cutting 1 inch and above need 85 amps or more. Choose on clean cut thickness rather than max severance, and match your compressor and circuit to the tier.
What is the best air compressor for a CNC plasma table?
Size the compressor to the machine air demand and add margin. Machines in this roundup need between about 250 L per minute at 65 PSI and 6.36 CFM at 80 PSI. Use a compressor with a large enough receiver that pressure does not sag mid-cut, add a coalescing filter and an auto-drain moisture separator, and run a dedicated air line with a regulator at the machine.
What PSI should I run my plasma cutter at?
Most machines in this roundup specify 65 to 80 PSI, so follow the manufacturer figure rather than pushing higher. The SILATU 85A uses about 70 PSI at 250 L per minute, the Bestarc 50A recommends 65 PSI, the LOTOS Apex needs 70 PSI at about 4.0 SCFM, and the LOTOS Supreme calls for 80 PSI at 4.5 SCFM. The HITBOX recommends a 50 to 60 PSI working range and cuts out below 30 PSI.
What pierce height should I use?
Pierce at roughly 1.5 to 2 times your cut height so the plasma column clears the kerf as it opens instead of blowing back through the hole. A Hypertherm table owner cites .120 inch as a working pierce reference. Start near 0.10 to 0.15 inch on thin material and cut at 0.03 to 0.06 inch, then move pierce height closer to 0.20 inch with a 0.06 inch cut height on 1/4 inch plate or thicker.
Are plasma cutter tips interchangeable?
Tips are interchangeable within a torch family and size, but not across brands. The Everlast machines use genuine Tecmo iPT60 and iPT80 parts, the LOTOS Apex is optimized for DC6309 drag and NCON series parts, and the budget inverters use PT31 and PT60 style torches. A mismatched electrode and nozzle pair causes arc instability that can look like a power supply fault.
Conclusion: The Best Plasma Cutters for CNC Tables in 2026
For most table owners, the SILATU 85A CNC Plasma Cutter is the best plasma cutter for a CNC table in 2026 because it combines blowback start, a 1:1 arc voltage output and a 5-pin signal port with the largest owner review base in this roundup. The Everlast PowerPlasma 52i is the choice when a genuine port and a real Tecmo torch matter more than amperage, and the 82i is the answer when your material runs past 1 inch.
Whichever you pick, budget the compressor, the filtration and the straight torch before you order. Those three items decide whether the machine cuts repeatably or fights you every job.
