Yeah, it's just scratch start and whatever tap is plugged in is all you get.
Aluminum down around 1/16" is very hard - but 1/8" and above is no problem.
Nice set-up, Dave. :thumbsup:
Tig is something I would love to learn. And would be a very handy to have around. Seems as though most things I have that need repair now-a-days, a tig set-up would be the way to go.
