6.
Insert the end of the cable into the externally threaded end of the
cable well and slide the well partially over the
cable
.
Place your
thumb over the open end of the cable well and slide the well over
the cable until the well bottoms out on the coupling. Thread the
well into the coupling and finger-tighten. This procedure forces
grease back around the cable end, eliminating any air pockets.
7.
Slide the metal cable adapter over the cable well. Thread the well
adapter into the end of the cable well and wipe off the excess
grease.
8.
Slide the spring and spring cover up over the coupling. Apply 1-2
drops of thread-locking compound to the cable adapter threads
and screw the adapter into the spring cover until it bottoms out.
9.
Install the cable assembly into the gun, being careful not to bend
electrode. Thread the cable adapter into the gun and hand-tighten.
10. Re-install nozzle assembly on gun.
Replacing Electrode
To replace a bent or broken electrode:
1.
Remove the nozzle assembly.
2.
Unscrew the contact from the resistor holder and discard.
3.
Apply dielectric grease to the threads of the new contact, and into
the end of the resistor holder. No air pockets are permissible.
4.
Screw the new contact into the resistor holder and wipe up excess
grease.
