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.
1. Unscrew and remove the shield cup from
the torch.

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