Gun Lead Connections
Power Cable - Air Cooled
A #2 power cable is used on the Prince ® SG spool 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 70-75 in-lb. The opposite 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, or any Positive
welding stud of the power supply.
Gas Hose
The gas hose is secured over the barbed gas fitting with a tie wrap. The
supply end of the gas hose uses our standard gas fitting (1/8” - 27 nps),
whereas the spool gun uses a 5/8” - 18 IAA RH male gas fitting.
Electric Cable
A seven-conductor control cable is used on the Prince ® SG Gun. The gun
end of the control cable is secured to the gun with a boot clamp and plugged
into the pot assembly and micro switch connectors. Slack is left in the
electric cable as it exits the back of the gun to prevent cable breakage. The
control end has a seven-pin “W” clocked amphenol connector.
Spool Gun Setup
Loading Electrode Wire
Unscrew, and remove spool cover.
Apply tension to drive rolls, so the wire will be picked up and fed through the
contact tip.
Straighten out the first six inches of wire and push it through the wire guide.
Jog the trigger until the wire is picked up by drive rolls and fed through the
contact tip.
Hold the brake assembly back towards the top of the gun; load the spool
onto shaft with the wire coming off the bottom of the spool. Release the
brake assembly to rest on the wire surface.
Replace the spool cover, making sure that the opening is over liner.
