Make sure the copper tip is intact and that the tip nuts have been loosened, then re-tightened to make clean contact of the tip to the gun barrels. The lamp is tied directly across the barrels, and when the tip is open circuited, the output voltage goes up enough to burn out the lamp. Hope this helps!
