gun. The
gun and Power Pin ends of the cable are stripped to the copper strands and
wrapped with a copper strip. A setscrew holds the cable securely in the gun
body and in the Power Manifold with torque requirements of 55-60 in-lb.
Conduit
The Python
®
Lincoln Compatible™ comes standard with a poly-lined conduit,
for feeding aluminum wire. The longer tting with a shallow groove is used
on the gun end. A set screw located on top of the gun handle secures the
conduit in place. The cabinet end of the conduit is secured into the Power Pin
connector with a set screw.
Gas Hose
The gas hose is pushed over a barbed tting on the gun body and secured
with the hose retainer. On the Power Manifold the hose has a crimped tting
screwed into the Power Manifold.

.
The gun end of the cable is secured with a cable clamp and the wires are
connected to the potentiometer, the micro switch, the motor and the gun
body mechanically. Slack is left in the electric cable as it exits the back of the
gun to prevent cable and/or wire breakage. The cabinet end of the control
cable uses a 7-Pin, Amphenol connector.

General
The Python

gun maintains a constant, steady, uniform
wire feed speed, regardless of curved or looped wire conduit. The constant
push exerted by the slave motor in the cabinet, combined with the pull of
the gun motor, causes the wire to literally oat friction-free through the wire
conduit. The 24VDC gun motor is controlled by a three and three-quarter (3
3/4) turn potentiometer in the gun handle.
