Gun Lead Connections
Power Cable
A #2 AWG power cable is used on the XR™ Python
®
. The gun end of
the cable has a tting crimped to the copper cable strands. This tting is
then threaded into the gun body. The cabinet end of the power cable is
incorporated into the Power Pin connector.
Conduit
The XR™ Python
®
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 incorporated into the Power Pin
connector.
Gas Hose
The gas hose is pushed over a barbed tting on the gun body and secured
with a plastic tie wrap. The cabinet end of the gas hose is incorporated into
the Power Pin connector.
Electric Cable
A multi-conductor control cable is used on the XR™ Python
®
. 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 10-
Pin, "X" clocked Amphenol connector.
Section 4 Operation
