6 – Power Supply Component Replacement
Install the torch lead and strain relief
If you are replacing just the torch lead cable, not the whole torch assembly, refer to Replacing the torch lead on page 182
for details on how to connect the new lead to the torch.
1. Are you installing a new strain relief?
 If yes, slide the new strain relief and strain relief nut over the new torch lead and up to the hole in the front panel.
 If no, continue with the next step.
2. Route the wires for the new torch lead through the hole in the front panel and then through the retention nut for the
strain relief.
3. Facing the fan side of the power supply, slide the ring terminal for the bundle of 3 white wires over the left stud
(labeled “WHT” on the center panel).
4. Slide the ring terminal for the red wire onto the stud on the right (labeled “RED” on the center panel).
 If you removed any other wires from the WHT and RED studs, reinstall them.
5. Use an 8 mm (5/16 inch) nut driver to tighten the nut on each stud with a torque setting of 23.0 kg-cm
(20 inch-pounds).
