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 remove the gas distributor.
4. Using the multi-purpose wrench (electrode area)
remove the electrode.
5. Install the desired electrode for the operation into
the torch head. The circular area around the
wrench used for electrodes will also align the elec-
trode in the torch head. This will prevent install-
ing electrodes on an angle and cross threading the
electrode in the torch head.

operation into the torch head.
NOTE
Be careful not to overtighten the electrode and tip
when reinstalling.

felt when installing the cup, check the threads be-
fore proceeding.
