Looking to see what other people have to say about Tig welding aluminum DC only. Those of us without AC/DC Tig machines CAN Tig aluminum, instead of having to use the Mig spoolgun. I personally haven't tried it yet, I'm waiting on my Superultra 205 to arrive(while I wait for my Powerultra 205). But from what I have READ about it, it is very do-able, even with Argon instead of Helium, just have to clean the metal really well, due to losing the cleaning action of the AC. Everybody chime in, let's see who has done it, wants to try it, who says it won't work, etc.... Thin vs thick, settings blah, blah
