Inspect and lubricate o-rings
1. Remove the black o-rings on the torch and replace them if they are damaged.
O-rings, bullet plugs, a water tube, and silicone lubricant are available for the main torch body of the quick disconnect
torch as part of kit 228780. See kits 428333 or 428334 for o-rings, a water tube and silicone lubricant for the
straight torch. Other o-rings are included with the consumables.
2. Apply a thin film of silicone lubricant (027055) to all o-rings.
3. The o-rings should look shiny, but there should not be any excess or built-up lubricant.
4. Replace all o-rings so they fit snugly.
5. Inspect all threaded consumables and remove any dirt in the threads.
6. Reassemble the torch.
Inspect the water tube and torch for damage
1. Verify that the water tube is not bent and has no pitting. Replace the water tube
(220521) if it is damaged.
2. Verify that the nozzle and electrode mating surfaces on the torch main body are not
damaged and have no pitting.
3. Use a clean cloth to wipe off the torch inside and outside. Use a cotton swab to
access hard-to-reach internal surfaces. Verify that you do not leave any cotton fibers
inside the torch main body.
4. Use compressed air to blow away any remaining particulates from internal and
external surfaces.
