Yes, Tom. I realized learning this thing via try and error could take years. Hopefully, TIG will be easier than OXY. But I don't know yet.
I did some brazing work on my basement water pipe in the past, that's way easier, no spatter (for some reason, copper or silver does not splash, but steel filler splashes like crazy during the welding process
). The biggest problem of brazing is color.
Copper filler in this pix, after applying oxidation agent 1st time. It won't turn black.
