Gun Lead Connections
Power Cable
A #2 AWG power cable is used on the Millermatic Compatible™ 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.
The power cable gun end is a threaded tting which screws into the gun
body. The cabinet end is secured in the central body with a set screw. These
connections utilize a conductive sealant and are tightened to a specic
torque setting (reference exploded parts drawing in the Appendix for details) .
Conduit
The Millermatic Compatible™ 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 secured into
the Power Pin connector with a set screw.
Gas Hose
The gas hose is pushed over barbed ttings on both gun body and the Power
Pin connector and is secured with a plastic tie wrap.
Electric Cable
A multi-conductor control cable is used on the Millermatic Compatible™
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.
