7.06 Servicing Hand Torch Components
A. Removing Torch Switch and Torch Head Assembly
Removing the torch control switch assembly requires
gaining access to the switch wiring and partially disas-
sembling the torch handle, as follows:
1. Remove the shield cup, tip, gas distributor and
electrode from the torch head assembly.
2. Roll the torch switch sheath back over the handle
to expose the tape covering the torch switch con-
nectors.
NOTE
Use a soap and water solution on the sheath
to assist in rolling.
