•
Reverse order of disassembly.
•
Apply a thin coat of silicone grease to O-rings before assembling mating parts. This facilitates easy
future assembly and disassembly for service.
•
Hand-tighten threaded parts.
•
Installing the electrode requires only moderate hand tightening. Electrode holder should always be
made tighter than the electrode.
over tightened parts will be difficult to disassemble and may dam-
age torch. Do not over tighten parts during reassembly. threaded
parts are designed to work properly when hand tightened, approxi-
mately 40 to 60 inch/pounds.
