5.6 Removal and Replacement of the Torch Body
A. PT-20AMX Torch
1. Cut and remove the shrink wrap at the back end of the torch handle. Unscrew the
handle from the torch body and slide it back onto the torch cable assembly in order
to expose the torch connections.
2. Remove the electrical tape which secures the short piece of vinyl tubing on the
pilot arc cable. Slide the tubing away from the torch and onto the pilot arc cable to
expose the pilot arc connector.
3. Use the 1.5mm (0.06") Allen wrench supplied in the spare parts kit to loosen the
pilot arc connector set screw closest to the torch body, being careful not to totally
remove the screw. Slip the torch's pilot arc lead out of the connector.
4. Unscrew the power cable fitting from the torch's power lead using a 11.2mm
(0.44") open-end wrench and remove the torch body.
5. Connect the pilot arc cable and the power cable to the new torch body's pilot arc
lead and power lead by reversing the steps taken to disconnect them. Tighten the
pilot arc connector set screw fitting firmly but do not overtighten. Torque the power
fitting to 2.3 n-m (20 in/lb).
6. Slide the vinyl tubing forward to cover the pilot arc connector and secure in place
with electrical tape.
7. Slide the handle forward and thread it firmly onto the torch body.
8. Slide the new piece of shrink tube over the torch handle and shrink in place over
the handle's end and the cable sheath.
