Lubricate Torch Cartridge O-Rings
An O-ring replacement kit with both torch and cartridge rings is available, catalog number 9-9488.
Coolant
Torch coolant becomes conductive with use and eventually will cause a shorted torch
condition. Torch coolant should be replaced every six months. Also remove and clean the
external coolant filter and the smaller filter located near the flow sensor.
Torch coolant is available pre-mixed or as concentrate.
