sure they are properly assembled. Check the ground clamp and
proper grounding to the unit. Check pilot arc wire to insure it is
properly connected to the unit.

Improper air flow. Increase the PSI on the regulator, check for
leaks in the hose, maintain a distance of 1/8” from the torch tip or
workpiece. If your unit comes with a manual Post Flow 2.5 or 5.0
switch make sure you leave it on 5.0 for more air to pass cooling
your torch tips.

have the proper PSI at the regulator.
