Examine and lubricate O-rings
Examine all of the O-rings on the torch body and consumables. Make sure that the correct amount of lubricant (a thin film)
is applied to these O-rings. Too much lubricant can prevent gas flow.
Examine the water tube and torch
1. Examine the water tube for bends and pitting.
2. Examine the nozzle and electrode mating surfaces on the torch main body for
damage or pitting.
3. Use a clean cloth to clean the internal and external surfaces of the torch. Use a
cotton swab to clean internal surfaces that are not easy to get to.
Make sure that you do not leave any cotton fibers on the inner surfaces of the
torch main body.
4. Use compressed air to remove any remaining particles from the torch main body.
