Hi,

 I have a question about annealing heavy gauge copper wire. Do you need to use flux or can you just heat it with a torch until it glows a dull red?

Thanks in advance, Lagniappe2005

I usually just heat it up and then quench. After all the work is done then I pickle and polish it.

Normal 0 One thing I learned the hard way with annealing wire, it may not be a problem with heavy gauge, is that torch annealing wire is too hard for me to keep the temperature even on all the wire, I have taken to annealing wire in a kiln. It is so much better.

I agree, wire is best done in a kiln...pieces can be done witha torch easily just look for an even deep cherry red - then you know your piece is annealed.
