Examine and lubricate O-rings
1. Examine all of the O-rings on the torch and consumables for damage or excess wear.
2. If you find damage or excess wear, replace the
O-ring.

Receptacle O-rings and torch O-rings for
the torch main body are available as part
of the torch rebuild and filter kit (428639
or 428640). 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.
