6. Reconnect the two torch head wires to the mating
connectors in the leads assembly.
7. Place the Torch Head Assembly in the handle shell
halves keeping in mind the following:
• Place the Torch Head Assembly switch leads
so that no connectors or wires extend beyond
the edge of the handle.
• Allow sufficient slack in the leads to avoid pull-
ing the leads tightly around the edge of the
handle.
• Position Pilot Lead under the Negative /
Plasma Lead.
• Position the Pilot Lead so that the screw will
not penetrate the Insulation Sleeve when the
handle halves are reassembled.
NOTE
For safety reasons, do NOT use the sleeving if it is
damaged during reassembly. Replace sleeving if
damaged.
8. Place the torch handle halves together and install
the five assembly screws as follows:
a. Insert the two screws at the Torch Head end
of the Handle and torque to 15 in-lbs.
b. Insert the two screws at the Torch Lead end of
the Handle and torque to 15 in-lbs.
c. Insert the center screw and torque to 15 in-lbs.
d. Check the Torch Trigger for proper operation.
It should move freely and not bind. If the trig-
ger binds, loosen the center screw only until
the Trigger moves freely.
