I figured out my error. The out put may potentially be 100-200amps, but the output voltage is low (like 25v) so it only needs to pull 25-50amps at 110 or less at 220. I was calculating the output amps 220. That would be require a dedicated service line. duuuh

what are you using for power source? anything over 30 amps is outside most household and portable generator power

I've got an old steel table saw top for a welding bench. Should make a decent heat sink.

Thanks for the advice. I've been a little concerned with getting small tight clean welds on the cabinets with a mig. Everything I've read suggests tig for the finish work. I'm not too worried about the practice. I'll build some scrap pieces until I'm comfortable, but it seems like the kind of thing ...

Thanks for the response. I'm also wondering about power. The only 220 outlet I have in my house is my dryer and it's only 30 amps. How do you power your's? Guess I need a generator too? MIG is looking a lot simpler and cheaper, but doing alum cabinets definitely sounds like a job for tig ...

I'm seeing some tig welders are not for aluminum. Some specifically say they are for aluminum. What's the difference?

I am a beginner with a project involving some alum square tube (for cabinets) Alum Diamond plate (flooring), and possibly some light gauge Alum sheet. Also have some steel square tube support to build (probably 1/16 x .75in x .75in). I've done basic brazing and pretty confident I can teach myself wi...
