I’m with you, I have not found the right combo for brass. Repaired an
element of a large brass casting this week and it was a struggle all
the way. Finally got a good weld using an alloy for eyeglass repair:
silver, pal., ? alloy. No color match of course, but I was able to
blend it pretty well.
I’ll get to re visit the problem next week as the store that sent me
the job gave incorrect orientation on a vital part, so I’ll be
cutting threw that weld to re align the assembly, and I’ll get a
chance to really study my weld. And try again. Argon didn’t seem to
make a noticeable difference.
