torch leads assembly to the RPT Adapter. Hold
the Adapter assembly stationary with a tool grasp-
ing the narrow hex nut. Use another tool to turn
the ATC Adapter or torch leads negative / plasma
lead onto the adapter assembly. The adapter in-
cludes a pair of wires with an insulated 'faston'
connector on the ends. This wire assembly must
be in a horizontal position, leading from the
adapter assembly toward the outside of the power
supply, and parallel to the solenoid assembly.
CAUTION
This positioning is important for proper power sup-
ply and torch operation.

power supply 'faston' connector previously dis-
connected from the original torch assembly. Slide
the insulating sleeve along the wire to cover the
'faston' connector. Secure the sleeve in place with
one of the wire ties included in this kit.
20. This adapter kit includes a wire harness assem-
bly with a four - pin connector. Connect the mat-
ing connectors on this harness to the mating wire
connectors on the ATC Adapter Assembly or torch
leads assembly. Connect the four - pin connector
to the power supply circuit board inside the power
supply front panel.
21. Reinstall the power supply cover per the power
supply manufacturer's instructions.
22. In installations with the ATC Adapter, connect the
torch ATC male connector to the ATC Adapter
