A seven conductor control cable is used on the Gooseneck Torch. The torch end of
the control cable is secured to the back of the torch with a cable clamp and the wires
are soldered to the motor, pot, and micro switch. The cabinet end has a seven pin
“S” or “W” clocked Amphenol connector. See schematic for wiring information.
6. DRIVE AND IDLER ROLLS
A. General
The Gooseneck torch comes standard with knurled drive rolls which will handle wire
diameters from .030-1/16 inch. Optional V-groove drive rolls are also available for
feeding aluminum wire if desired (see Optional Kits).
Drive roll tension is accomplished by means of a pressure-adjusting screw located
on the left hand side of the torch. Proper tension is achieved when wire does not slip
if a small amount of pressure is added to the wire as it exits the tip.
NOTE: Over-tightening of the drive rolls will cause excessive knurling and/or defor-
mation of the wire.
B. Drive Roll Installation/Removal
1. Remove right handle.
2. Rotate drive roll by jogging drive motor with trigger switch or with finger tips until
