I finally posted a pic. but I keep referring back to the lamp post video. I just don't see how my bead looks that bad. when I go back to dc and use silicon bronze it perfect. this ac deal and aluminum bronze thing just kills me.Otto Nobedder wrote:Nope.

Patience, practice, CLEAN X 3, and more patience.
I can't advise you on the "how", though. Brazing is one place I'm still an oxy-fuel/flux fan, but my stuff does not have to look good, only meet liquid oxygen service requirements under pressure. I frequently repair joints that were previously TIG-brazed, because they don't hold up to the thermal cycles.
