What Tim said. But the flux must be ACID. My local weld shop has some
proprietary formula stuff that works great but good old HCl has merit.

good catch - I didn't think of mentioning ACID flux - I've had good luck
with the paste stuff sold for soldering copper pipes - it's a little easier
to work with (well, a LOT easier to work with) than liquid HCL, and with a
wire brush (by hand) and some heat it will clean up a solder joint nicely
for resoldering.

You REALLY want Zinc Chloride - or "cut acid" HCL with as much zinc
as it will disolve.
