Examine and lubricate O-rings
1. Examine all of the O-rings on the torch and consumables for
damage.
2. If you find damage, replace the O-ring.

Receptacle O-rings and torch O-rings for the torch main body
are available as part of kit 428252. Other O-rings are included
with the consumables.
3. Apply a thin film of silicone lubricant (027055) to all O-rings.

The O-rings should look shiny. Too much lubricant can prevent
gas flow.
4. Install all O-rings so they fit snugly.
5. Examine all threaded consumables, and remove any dirt from the
threads.
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.
