[QUOTE="pholmann, post: 469215, member: 5330"] I found some pretty helpful hints from weld.com and some youtube vids through a guy called mr tig. I need to check to see if I am trying to weld aluminum through dc positive or negative. I have never even checked the polarity of my machine since I bought it used. My understanding is that steel and stainless is DC negative and aluminum is DC positive. [/QUOTE]
