the Power Supply is ON.
Remove the consumable torch parts as follows:
NOTE!
The shield cup holds the tip and
starter cartridge in place. Position
the torch with the shield cup facing
upward to prevent these parts from
falling out when the cup is removed.

torch.
NOTE!
Slag built up on the shield cup that
cannot be removed may effect the
performance of the system.
2. Inspect the cup for damage. Wipe it clean or
replace if damaged.

and drag shield cap. Do not lubricate the O-ring.
