Backfiring:

Improper operation of the torch may cause the flame to go out with a loud snap or pop. This is called backfire. It is caused by one of a few things. The first thing to do is turn the gas in the torch off, check all the connections and try relighting the torch. Backfiring can be caused by touching the tip against your workpiece, overheating the tip, operating the torch at other than recommended gas pressures, by a loose tip or head or by dirt on the seat.
