FWIW, I can gas weld .125 AL easily, I can gas weld .065 barely, and I can't gas weld .035" Al at all. I can tig weld .035" if I'm careful and keep the heat down. I've heard that people can run Tig beads on pop cans, but I can't imagine doing so, and flashing material is about that kind of thickness. So on a scale of one to ten, ten being easiest, tig is about a

10 and gas welding is about a 0 when trying to weld pop can thickness aluminium. I think.

Thanks, Brian.

All the more reason for me to get another toy, right? Tig, here I come.
