Gun Lead Connections
Power Cable - Air Cooled
A #2 power cable is used on the Cobra ®
SX gooseneck gun. The gun end of the
cable is stripped to the copper strands
and wrapped with a copper wrap. A
setscrew holds the cable securely in the
gun body with torque requirements of
55-60 in-lb. The cabinet end of the cable
is equipped with a 1/2" ring lug which
attaches to the top hole on the side of
the power block. Supplied with this gun
is a 3/8-16 x 5/8" bolt, a 3/8" spring lock
washer and a 5/8" flat washer to attach
the ring lug to the power block.
Conduit
The Cobra ® SX gun 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. Spiral steel conduits are available for hard wire.
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.
The cabinet end of the gas hose uses our standard gas fitting (1/8” - 27 nps).
