CONNECTING THE GUN CAbLE TO THE WIRE FEEDER

A variety of gun and cable assemblies are available for the LN-9 GMA models. See the Accessories section of this manual.

Lay the cable out straight. Insert the connector on the welding conductor cable into the brass conductor block on the front of the wire drive unit. See Figure A.10. Make sure the connector is fully seated and tighten the plastic thumbscrew. Keep this connection clean and bright. Connect the control cable polarized Amphenol plug into the mating 5-cavity receptacle on the front panel of the wire drive section.

FOR GMA GUN CAbLES:

Install the barbed fitting and union nut to the 5/8-18 female inert gas fitting on the front of the LN-9 GMA wire drive section. Connect the 3/16" I.D. gas hose from the gun cable to the barbed fitting.

When you remove the gun, you can easily detach this fitting by loosening the union nut.
