X2 what most are saying, buy now what you want later. And schooling is great, but there's no replacement for hands on. The only "training" I've had is some tips from a couple old timers at work, and that went a long way for me. My current welder is WAY better and more capable than I ever will be, but there's nothing I would ever weld that it wouldn't do. Just sucks I need a gasoline powered ac/dc welder to run mine! Oh yea, I think it's 100% duty cycle too, but I haven't been able to confirm it yet. I just know that it'll go as long as you wanna run a bead. I think it's more dependent on which welder I'm getting power from.
