[Cooper]

I'm sure this stuff isn't made by Hobart, I looked for a manufactuer on the back but no luck just a brand name. I have some flux and solder for aluminum but I don't know where I put it!!! I used it to solder lipo base tabs as they are aluminum (as people will say they are copper and you can't solder aluminum, but they are aluminum base tabs ). Yes for what I've gotten into the flux is the main part, has to break the oxide on aluminum. Even just milled will quickly develope an oxide covering. That's why they say to use stainless steel wire brush on aluminum during heating when brazing, soldering. Let me know what the stuff you get works like as I just don't have enough work to warrent a purchase of tig welder. But am trying very hard to justify a purchase of one. .
