help! i feel like i’m back to square one and have forgotten how to do
everything i’ve been doing. something is suddenly going very very
wrong with my soldering. i’ve been working on a pendant that has a
large bezel setting and many granules and a bale. for some reason,
pretty much every solder seam fails at some point. my bezel seam tore
when i was setting my stone. many of the granules popped off after
tumbling but during polishing. and my bale just popped off just as i
was finally done with this thing for the third time. i have had it!!!
i’ve changed a few things but i’m not sure what’s responsible. is it
(1) i am waiting to get my acetylene tank refilled tomorrow and have
been using a small propane tank in the meantime. i can’t imagine
that this is the problem as i think propane is actually hotter, but
perhaps my heat control is just off with the different gas.
(2) am i not letting the solder flow long enough? it seems to be
running but i was helping it along at times with my pick.
(3) am i using too much solder? or not enough? which infraction is
more likely to result in weakness?
(4) i switched fluxes – could this have anything to do with it?
any ideas would be very welcome - i’m pretty much at my wit’s end!!
i’ve often had trouble with granules falling off in the past but
never ever have i experienced anything like this!!!
thanks very much,
