Looking to get a welder for the house

Well, you can get a spoolgun and use that, it does support it, but I do not have one. I have a Python push-pull gun for my PM300 when I need to weld a lot of aluminum, but I usually just AC TIG with my Syncro 250. 210amps with a spoolgun should be good for 3/16" aluminum.

You can weld aluminum on DC using pure helium, that is the original heliarc after all, but that's a specialized field these days and AC TIG is much more common and much more suited to the vast majority of aluminum welds. S/F....Ken M
