When the heat it too high the wire sticks out, strikes the arc and immediately burns back to the tip (the "pop"). Wire feeds out again and repeats. It will eventually burn clear back into the tip and jamb. Speed up the wire feed or turn down the heat.
Too much stick out can cause popping too.

Nothing like a ball of glowing steel burning through your shoe to remind you to cover up.
