GENERAL GUN CONNECTION GUIDELINES
The instructions supplied with the gun and K1500
series gun adapter should be followed when installing
and configuring a gun. The following guidelines are
general procedures only that are not intended to cover
all guns.
1. Check that the drive rolls and guide tubes are prop-
er for the electrode size and type being used.
2. Lay the cable out straight. Insert the connector on
the welding conductor cable into the brass conduc-
tor block on the front of the wire drive head. Make
sure it is all the way in and tighten the hand clamp.
Keep this connection clean and bright.
Note: For Fast-Mate and European connector style
guns, connect gun to gun connector making
sure all pins and gas tube line up with appropri-
ate holes in connector. Tighten gun by turning
the large nut on gun clockwise.
3. For GMA Gun Cables with separate gas fittings,
connect the gas hose from the wire drive unit to the
gun cable barbed fitting.
