CV-300

THIS CONNECTOR IS MEANT TO BE USED WITH LINCOLN POWER SOURCES WHICH HAVE A 14-PIN

WIRE FEEDER RECEPTACLE. IT IS DESIGNED TO ALLOW THE USER TO MAKE CONNECTIONS

TO ANY OF THE 14 CIRCUITS PRESENT IN THE WIRE FEEDER RECEPTACLE.

CONSULT THE WIRING DIAGRAM OF THE POWER SOURCE AND WIRE FEEDER THIS ADAPTER WILL BE USED WITH. NOT ALL CIRCUITS ARE PRESENT IN EVERY POWER SOURCE, NOR ARE THEY REQUIRED FOR PROPER WIRE FEEDER OPERATION.

1.TURN THE POWER SWITCH OF THE WELDING POWER SOURCE OFF BEFORE INSTALLING THIS ADAPTER TO WIRE FEEDER CABLE.

2.CONSULT THE APPROPRIATE EQUIPMENT WIRING DIAGRAMS FOR THE CONNECTIONS TO UNIVERSAL ADAPTER.

THE STANDARD CONNECTOR PIN DESIGNATIONS AND FUNCTIONS ARE SHOWN BELOW.

NOTE: 115V AC (31, 32), 42V AC (41, 42), 24V AC (SPARE) AND TRIGGER CIRCUIT (2, 4)

MAY OR MAY NOT BE ISOLATED, INDEPENDENT CIRCUITS INSIDE THE WELDER.

3.USE LUG, CRIMP SPLICE OR SOLDER CONNECTIONS AS REQUIRED AND INSULATE EACH USED AND UNUSED LEAD IN THE UNIVERSAL ADAPTER. THE INSULATING METHOD MUST BE RATED FOR 120V AC OR GREATER.
