torch lead.
7. To reconnect the torch lead, route the wires and the gas supply line for the torch lead through
the hole in the front of the power supply.

goes in approximately .65” (16 mm).
9. Slide the ring terminal for the white wire group over the left stud (labeled “wht” on the center
panel). Slide the ring terminal for the red wire onto the stud on the right (labeled “red” on the
center panel). Tighten the nuts onto the studs.
10. Thread the orange, blue, and purple wire group over the center panel with the wires resting in
the notch in the panel. Tip the endcap away from the power supply and press the connector
into the slot on the power board.
11. Tighten the torch lead’s strain relief onto the power supply by screwing it into place and
reposition the endcap.
4. Carefully tilt the front endcap away from the power supply. The orange, blue, and purple wires
from the torch lead are connected to the power board with a 3-pin connector at J12. Remove
