Plasma Cutter, CUT50 55Amp 110V/220V Dual Voltage IGBT Cutting Machine

This was the least expensive dual voltage 50 amp plasma I could find; I decided to try it.I know this Chinese welding and cutting equipment rather well, as I was one of the early group of importers here in the USA.There have been improvements for sure, this 50 amp/ IGBT unit is coming in cheaper than MOSFET/ 40 amp units used to.This machine worked well out of the box, with 220v input I got a good cut in 1/2", roughly 12"IPM, so pretty darn good!At 110V I fit 3/8 " at about the same travel speed.I did notice a bit of choking at 110V and suspect the small wire gauge of a garden variety 16ga.extension cord was causing a voltage drop, so I suggest a larger gauge, 14ga. Or such, if you need a cord.This is a nice lightweight and portable unit, which is exactly what I needed.The pt-31 torch is old style with the paddle trigger, not sexy, but easy to operate with gloves.External regulator, again, not sexy, but easily serviced, and keeps high pressure air on the outside of the machine.Simple outer case that is not dependent on the plastic parts should they break down the road.Like the addition of the post flow air and adjustment, especially useful when doing the higher amp cuts.Main criticism- ground lead only 3' long, 6' would be better.Small suggestions, no mention of importance of moisture free air supply, and no recommendation for air pressure; I found the pt-31 seems to like 40-50 psiAlso a heads up if you have troubles with the cut face not being at 90 degrees to plate surface, pt -31 tip has 2 sets of 4 little air grooves; rotating the tip and reorientation of the groove can affect this, running against a straight edge can cause this to need attention as well.Bottom line here $200 to get a very impressive cutting capability in your workshop or at your maintenance situation., Inexpensive readily available consumables, good cutting thickness, high portability, so as long as it shows a good lifespan, it is a winner.Fan after-run after power off, should help the electronics, another nice feature.

Good little plasma cutter for the price. Actually can't beat the price. Has held up well and have mounted to a cnc rail system for a cnc plasma. Works great.

So I didn't expect much to be honest. I used to own a commercial plasma torch but got rid of it because it required to much power to run, I figured it was time to get another as the cut off wheels only can do so much. I looked at lots of them from $2000 plus hi end machines to the ones at Harbor freight and decided to buy what I thought was a cheap investment as this was only $300 so defiantly on the low end of the price scale.When it got here it was well boxed and there was little to put together so with in a few minutes it was ready to use. I put tape on the air fittings as I read they tend to leak air, you need to cut the air hose to a desired length as it comes much longer than it needs to. It did come with the 120V cord as well as the 220V and a small bag of tips and cones.I didn't even read the pamphlet I just set the machine to 20psi and put the knobs to 28amps on 120V and bam it cut great threw 1/8" diamond plate, a little slow but common what can you ask for out of a $300 machine. Today I cut threw a 1/4" weld and two sheets of rusty 1/8" steal at once with 20PSI and 36amps like to wasn't even there. I am very impressed with this little machine and as long as it doesn't burn up over time I will recommend it.The tip it comes with is short and will junk out after an hour or so of use but the replacements they send in the bag are much better and require less amps to cut, wire brush the tip after each use and make sure you grind the ground surface for best results. So far I think it is as good as my old commercial unit and about 1/10 the size, these things have come a long way.

Bought for a food plant, where everything we do is stainless steel. Got tired of cutting everything with an angle grinder.Stainless steel takes almost twice the heat as mild steel. For $200, this performs as well as the $2,700 my last job had. I’ve had it for a month and used 3-4 times a week, normally on 3/32 or 1/8” sheet metal. Will cut both on 110V, roughly 25 amps. Getting up closer to 35 output amps, it will trip our 15 amp breaker occasionally. But on 220v input, it cut 1/4” steel no problem. Roughly 55 psi input.The ground lead that it comes with has a thin cable and is short, but it’s a dinse-25 connector so can be replaced cheaply. Comes with a few extra cups, collets, and electrodes. The air regulator and lines and clamps work as they should. The power cord could be longer, but that’s an easy fix. The cutting torch isn’t bad, and the protector on it is nice.Over all, fantastic for the price. Hasn’t died yet. Nice and portable, worked out of the box and setup is very easy.
