Gun Lead Connections
Power Cable - Air Cooled
A #2 power cable is used on the Cobra
® SX Lincoln Compatible™ 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 Cobra ® SX Lincoln Compatible™ comes standard with a poly-lined
conduit, for feeding aluminum wire. The longer fitting 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 fitting on the end of the gun body and
secured by twisting the hose retainer to the end of the hose (shown below).
The hose retainer is re-usable and can be removed and re-installed as
needed.
Control Cable
A multi-conductor control cable is used on the Cobra ® SX Lincoln
Compatible™ gun. 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.
