1.Unplug the machine or turn power switch to the off “O” position.
2.Pass the insulated terminals of the gun trigger con- trol leads, one at a time, through the rectangular “keyhole” opening (item F) in the case front. The leads are to be routed under the wire feed unit and through the cable hanger on the inner panel.
3.Insert the connector on the gun conductor cable through the large hole in the
4.Connect the insulated control lead terminals to the two insulated 1/4" (6.4 mm) tab connector bushings located above the “Gun Trigger Connection” decal in the wire feed section. Either lead can go to either connector. Form the leads so that they are as close as possible to the inside panel.
CAUTION
The gun trigger switch must be a normally open, momentary switch. The terminals of the switch must be insulated from the welding circuit. Malfunction of the
