2. Using the multi-purpose wrench (5/8 inch slot) remove the tip.
3. Tilt the Torch Head to remove the gas distributor. The end of the multi-purpose wrench can be used to help

4. Using the multi-purpose wrench (electrode area) remove the electrode.
5. Remove gouging water extension tube, if used.
6 . Install the desired electrode for the operation into the Torch Head. The circular area around the wrench used
for electrodes will also align the electrode in the Torch Head. This will prevent installing the electrode on an
angle and cross threading the electrode in the Torch Head.
7. Install gouging water extension tube if required.
8. Install the desired gas distributor and tip for the operation into the Torch Head.
NOTE
Be careful not to overtighten the electrode and tip when reinstalling.
9. 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.
