9 – Power Supply Component Replacement
Install the quick disconnect receptacle
1. Secure the quick disconnect receptacle to the front panel by tightening the 4 supplied mounting screws to 23 kg-cm
(20 inch-pounds). See Figure 91 on page 234.
2. From the front of the power supply, insert the small end of the silver-plated fitting into the center hole of the quick
disconnect receptacle until fully seated.
3. Install the plastic washer over the silver-plated fitting and the plastic hub on the rear of the quick disconnect
receptacle.
4. Place the ring terminal over the silver-plated fitting and tighten the brass nut onto the silver-plated fitting. Tighten the
nut to 46.1 kg-cm (40 inch-pounds), but do not overtighten – the plastic washer should be able to spin when the
brass nut is installed.
5. Push the 90° push-to-connect fitting onto the silver-plated fitting until fully seated.
6. Route the nozzle wires through the protective sheathing in the center panel.
7. Route the torch interface cable through the center grommet.
