Hi,

I'm practicing sweating 1/2" copper pipes, but I find that when
sweating on small fittings, such as a coupling or an elbow, I melt the
solder in the first joint when working on the second because they are
so close. What's the trick to avoid this problem?

Speed, number one--do both at same time.

Second, if that isn't possible, wrap damp cloth around the first while
doing the second.

Third, practice, practice, practice...will lead to #1


Why mess around. Braze the fittings. 5 percent sil-phos. don't need flux.
Works every time.
