Description
The Simder Upgraded CUT-50 PRO is a 50A pilot arc plasma cutter that slices through rusty, painted, and dirty steel without touching the surface — clean cuts up to 1/2 inch and severance cuts up to 3/4 inch. Non-touch pilot arc starting, 2T/4T modes, and PSI/MPA pressure display make it the $159.99 workhorse for farm, auto, and fabrication cutting.

Built For
- Rusty and painted steel — pilot arc starts without touching the surface, no contact tip fouling
- Farm & ranch salvage — cut through corrosion, paint, and dirt in one pass
- Auto body & frame work — 1/2" clean cuts through panels and frames

Key Technical Features
What is pilot arc and why does it matter?
Pilot arc starts the plasma jet before the torch touches metal. You can cut rusty, painted, or coated steel without the tip ever contacting the surface — no tip fouling, no pre-cleaning, no failed starts.
What does the PSI/MPA display do?
Plasma cutting depends on correct air pressure. The display switches between PSI and MPA so you can match your compressor output exactly — the most common cause of bad cuts is wrong air pressure.
How thick can it cut?
Clean cuts up to 1/2 inch (12mm) and severance cuts up to 3/4 inch (19mm) on mild steel at 220V. On 110V, capacity is reduced — use 220V for full performance.
What air compressor do I need?
A standard shop compressor with the flow the manual specifies. The air regulator and hose are included — set pressure using the built-in PSI/MPA display.
What's the difference between CUT-50 and CUT-50 PRO?
Same price class, different start type: the CUT-50 (40A) uses contact start — touch the steel to begin. The CUT-50 PRO (50A) uses pilot arc — start without touching, ideal for rusty or painted surfaces.
Real-World Use Cases
Farm equipment salvage
Cut rusted plow parts and painted implement steel without grinding surfaces clean first — pilot arc doesn't care about the coating.
Auto body panel cutting
1/2" clean cuts through body panels and frames, with the thin-material control of adjustable current.
Fabrication shop prep
PSI/MPA monitoring keeps cuts consistent across a workday — set pressure once, cut all afternoon.
Frequently Asked Questions
What's included in the box?
AG60 plasma cutting torch, gas hose, air regulator, and operation manual.
Can it cut rusty or painted metal?
Yes — that's what pilot arc is for. The arc starts without touching the surface, so rust and paint don't foul the tip.
How thick can it cut?
Clean cuts up to 1/2 inch (12mm) and severance cuts up to 3/4 inch (19mm) on mild steel at 220V.
Does it need an air compressor?
Yes — plasma cutting requires compressed air. The regulator and hose are included; you supply a standard shop compressor.
Is it also a welder?
No — cutting only. For weld-and-cut in one machine, see the Simder MIG-250 6-in-1 or SD-4050 Pro 10-in-1.
Is it good for beginners?
Yes — 2T/4T modes and the PSI/MPA pressure display remove the two hardest setup variables for new plasma users.
