GUNS AND CABLES ASSEMBLIES

A variety of Lincoln 10' (3.0m) or 15' (4.6m) gun and cable assemblies are available for use with the LN-15, including the Magnum™ models for GMAW, K126 or K115 models for Innershield®, and more.

The LN-15 comes factory equipped with a K1500-2 gun connection kit, designed for guns having a Magnum Tweco™ compatible #2-#4 connector. Many other guns can easily be used with the LN-15 with other K1500 series gun connection kits.

Gun Cable Connection to the Feeder

Lay the cable out straight. Insert the connector on the welding conductor cable into the brass bushing on the front of the wire drive unit. Keep the all mating sur- faces clean. Make sure it is fully seated and tighten the thumb screw.

Connect the control cable plug into the 5 pin recepta- cle on the front panel of the wire feeder.

ELECTRODE POLARITY

The LN-15 automatically adjusts for positive and neg- ative polarity. When welding with negative polarity procedures, the voltmeter will display a "-" sign; exam- ple "-23.6" Volts.

CONTROL CABLE CONNECTIONS

For Control Cable model, attach the control cable from the LN-15 to power source. Do not use more than 150 ft (45 m) of cable.
