Torch Front End Assembly

CAUTION
• Reverse order of disassembly.
• Apply a very thin coat of silicone grease to O-rings before assembling mating parts. This facilitates
easy future assembly and disassembly for service.
• Installing the electrode requires only moderate tightening. If the electrode holder is made tighter
than the electrode, it is possible to change worn electrodes without removing the electrode holder.
• Turn on the coolant circulator and purge the gases through the torch.
When assembling, place the nozzle inside the nozzle retaining cup and thread the nozzle retain-
ing cup/nozzle combination on the torch body. This will help align the nozzle with the assembly.
The shield cup and shield cup retainer should be installed only after installing the nozzle retain-
ing cup and nozzle. Otherwise the parts will not seat properly and leaks may occur.

Maintenance/troubleshooting
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.
