TORCH CONSUMABLE PARTS SELECTION
To change the torch consumable parts use the following procedure: NOTE The tip, gas distributor, and electrode are
held in place by the shield cup. 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
Head Assembly. Figure B Consumable Parts.
2. Remove the tip, gas distributor, and electrode.
3. Install the electrode, gas distributor, and tip.
4. Hand tighten the shield cup until it is seated on the
torch head. If resistance is felt when installing the
cup, check the threads before proceeding.
Improper assembly or use of non standard torch parts can cause the torch head to short and may
overheat or damage the torch.
