I believe the popping is simply from improper seating of the torch tips. Is
there another common cause?

There are some causes to popping. If everything is well sealed.
* to low gas speed. If the gas is coming out to slow, the flame can burn
back (into the tip), get a lot of volume to burn and thus explode.

* to much heat. Acetylen is quite nasty. To high a temperature (or
pressure), it falls apart with a **bang**

* a quite unexpectable but possible cause: if you lead acetylene through
a copper alloy above 80% (brass is OK) you get whattheheck. Some kind
of explosive that is very sensible. Now if you have cleaned the brass
parts with some chemical that dissolves the tin you have 100% copper on
the surface. And you get the chemical reaction that will produce the
explosive stuff. Best to clean the brass parts mecanical, not chemical.
