Examine The Torch Receptacle - Hypertherm XPR300 Instruction Manual

6. Clean and lubricate the torch if it does not need
replacement:
a. Use a clean, lint-free cloth to wipe the internal
and external surfaces. (See Figure 52.)
b. Use compressed air to remove debris from the
internal and external surfaces.

A cotton swab can be used for internal
surfaces that are difficult to reach. Do not
leave cotton fibers inside of the torch.
c. Apply a thin film of silicone lubricant (027055) to any O-ring that does not need
replacement and that looks dry.

The O-rings should look shiny. Too much lubricant can prevent gas flow.
Remove excess lubricant if found.
