A 40A plasma cutter that starts without high-frequency — contact-start simplicity for clean, repeatable cuts on mild steel, running on 110V or 220V household power.
The CUT-50 pairs a PT31 torch with adjustable cutting current and post-flow air cooling. Contact start keeps the torch simple and the shop quiet — no high-frequency unit sparking across your electrical system. Set your amperage, drag the tip, cut.
Plasma Cutting. Start to Finish.
One torch, one air line, one dial. The CUT-50 keeps cutting simple so your first clean cut is not your last.
Contact-start PT31 torch
Drag to start
Touch the tip to the workpiece and pull — the arc starts on contact. No high-frequency starter, no stripped spark plugs or CNC chatter nearby.
Adjustable cutting current
40A output
Dial the amperage to match the stock in front of you, from thin sheet to heavier plate, with post-flow air cooling the torch and cut edge after every pass.
Air setup included
Regulator in the box
Connect a standard shop compressor, set pressure on the included regulator, and you are cutting. Gas hose and clamps come with the machine.

Frequently Asked Questions
Does the CUT-50 need an air compressor?
Yes — plasma cutting needs compressed air. Any standard shop compressor works, and the air regulator and gas hose are included in the box, so setup is: compressor → regulator → machine → cut.
What does "contact start, no high frequency" mean?
The arc starts when the PT31 tip touches the metal — there is no high-frequency starter unit. That keeps the torch simpler, reduces electrical interference with nearby electronics, and gives you one less component to fail.
How is it different from the CUT-50 Pro?
The CUT-50 Pro adds a 50A output, a non-touch pilot arc (the arc starts before the torch touches rusty or painted metal), and a digital pressure display in PSI and MPa. If you cut thick or surface-rusted plate regularly, step up to the Pro; for straightforward DIY cutting, the CUT-50 is the value pick.
Which consumables does it use?
PT31. SSimder stocks a 67/71-piece PT31 consumables kit (electrodes, tips, shields) so every wear part your torch needs is one click away — no hunting for off-brand tips.
What can it cut?
Mild steel and common workshop metals in DIY thickness ranges. For consistently clean 1/2-inch cuts and severance work up to 3/4 inch, the 50A CUT-50 Pro is the right tool.
What warranty does it carry?
Every SSimder welder and cutter carries a 3-year warranty — the same policy across the line, spelled out on our warranty policy page.
