Based on Grant's response, my reply is a little off-topic, but I will
mention anyway: if your torch is in good shape (O-rings OK, etc) then
popping while you are welding probably means you are running too small a
flame for the tip size, allowing the flame to travel back through the
opening.

On mine it was bad "O" rings.
