LN-25™ CONTACTOR KIT (K443-1 FOR CODES

BELOW 10500, K443-2 FOR CODES 10500 TO 10558 OR K433-3

FOR CODES ABOVE 11144)

(Factory installed in K449 Model.)

The internal contactor provides “cold” electrode until the gun trigger is pressed, and a fixed burnback time delay to prevent electrode from sticking in the weld crater when the trigger is released. The contactor is rated for use up to 300 amps. A cold inch switch allows the wire to be loaded into the system without being electrically “hot”.

Installation Instructions are included with the kit.

CAUTION

These kits can only be used with LN-25™’s above Code 9200 or with LN-25™’s equipped with a G1757- 3 (or higher part number) Control PC board. To prevent possible damage to the LN-25™ with internal contactor, do not connect to non-Lincoln TIG or Square Wave power sources. TIG high frequency power should never be applied to the LN-25™.

NOTE: The K443-1, K443-2 or K433-3 cannot be used with K431-1 or K624-1 Remote Output Control Kit. If remote voltage control is desired along with the internal contactor, obtain a K444, K444-1 or K444-2 Remote Voltage Control Kit.

REMOTE OUTPUT CONTROL OPTIONS AND CONTROL CABLE ASSEMBLIES

Remote Output Control Options are available to pro- vide the LN-25™ with the following additional features:

1.“Cold” electrode until the gun trigger is pressed, and a fixed burnback time delay to prevent elec- trode from sticking in the weld crater when the gun trigger is released.

2.Remote (10K ohm rheostat) control of power source output arc voltage level.

K431-1 REMOTE OUTPUT CONTROL KIT

(For use with K432 Remote Control Cable and K433 Power Source Remote Box.)

The Kit includes a Remote PC board and control cable receptacle which mount and connect inside the LN-25™ control box per the Installation Instructions (M17584) included with the kit.

NOTE: If the K431-1 Remote Output Control Kit is installed but the LN-25™ is to be used without the K432 Remote Control Cable Assembly, then the Re- mote Board harness plug must be removed from the 12-pin receptacle on the Control Board and the jumper plug (T13498-21) reinstalled.

K433 POWER SOURCE REMOTE BOX

(Requires K431-1 Remote Output Control Kit installed in LN-25™ using K432 Remote Control Cable.)

The Remote Box is designed to mount and connect to Lincoln Idealarc® semiautomatic power sources per the Installation Instructions and power source connection diagrams included with the kit.

The Remote Box provides the proper welding power source control interface and isolated 24V AC input supply for the LN-25™ equipped with the K431-1 Remote Output Control Kit.

Remote Box requires 115V AC, 50/60 Hz input and a welding power source using a contact closure output pilot circuit, as available on appropriate Lincoln weld- ing power sources.

K432 REMOTE CONTROL CABLE ASSEMBLY

(Requires K431-1 Remote Output Control Kit installed in LN-25™ and K433 Remote Box mounted to power source with 115V AC auxiliary power.)

The K432 control cable assemblies include an elec- trode cable, rated for up to 500 amps 60% duty cycle, and a 6-conductor control cable with pin connectors on both ends. Available in 25, 50, 75 and 100 ft. lengths.

The cable assembly end with the socket pin connector connects to the LN-25™ per the Instructions included with the K431-1 kit.

The cable assembly end with the male pin connector connects to the K433 and power source per the In- structions included with the K433 kit.

K363P READI-REEL® ADAPTER KIT

Adapts Lincoln Redi-Reel® coils of electrode 30 lb. (14kg) and 22 lb. (10kg) to a 2” (51mm) spindle. Durable molded plastic one piece construction. Designed for easy loading: adapter remains on spindle for quick changeover.
