[QUOTE="patooyee, post: 432963, member: 483"] It's a DC-only unit, so no aluminum. I'm not sure what its max rated steel thickness is but most machines will generally do thicker than rated. Its max amps is 160 on 220-volts. The general rule of thumb is 1 amp per .001" thickness so that means .160 would be about its max "on paper." But I would feel plenty safe doing .25" in a single pass with it at 160 amps and of course much thicker with multiple passes and / or preheating. Like I said, at 100 amps it was able to fairly easily melt right through that .120 wall when according to the 1-amp/.001" rule I should have been at 120 amps. I like that little machine though. It holds a nice tight arc with everything I've done so far. I'm going to get a flex-head torch for it and start using it for all my roll-cage welding. Edit: I've had the same experience on .120 tube at 100 amps using my Synchrowave so I don't think its just the little machine running hot. I think the 1-amp/.001" rule is just a general guideline. I've found it to result in being too hot on just about everything I've tried so far in fact. Its more accurate the thinner you go, IMHO. For instance, I found that 50-60 amps was about perfect for some .060" aluminum I was doing for that switch panel. [/QUOTE]
