torch to power source connections

Consult your power source instruction literature to learn how to access the torch connections.
The order in which the torch connections can be made will vary with the power source used. Study your power
source to determine the order which will best allow you to make the connections correctly with a wrench.

The PT-26 torch uses a "C" sized left hand thread fitting for the negative terminal and coolant connection. Con-
nect this fitting to the corresponding female fitting on the power source and tighten it firmly with a wrench.
After tightening the fitting, slide the rubber boot on the power cable over the connection. The "B" sized right
hand fitting is used to make the positive terminal and coolant connection. Tighten it firmly as well.
The plasma gas and shield gas connections are made with two "B" sized fittings, each with a different thread.
Tighten them firmly with a wrench at the corresponding power source panel fitting.
The torch switch connection is made with the 5-pin plug on the torch switch lead. Insert the plug into the socket
on the power source and twist the locking ring to secure it in place.

retrofits to older power sources

The PT-26 torch may be retrofitted to older Deuce Pack 150 power sources. This requires installation of a new
plumbing box. The kit for this is P/N 000759.
