LN-25

C-4

ACCESSORIES

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

16-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 (M15324) 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 welding 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

electrode 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

(M17584) 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.

K439 REMOTE EXTENSION CABLE ASSEMBLY

The 50 ft. Extension cable assemblies are used to

extend the K432 Remote Control Cable Assembly

when longer cable lengths are required.

Multiple K439 Extensions may be used, however, to

prevent excessive weld cable voltage drops, the 500

amp max. rating of the K432 should be reduced by

at least 50 amps for each K439 Extension used. For

example, if three K439 Extensions are used (150 ft

total extension), the maximum welding current used

should be less than 350 amps.

The K439 Extension cable end with the male pin

connector connects to the K433 Remote Box and

power source per the Instructions included with the

K433 kit.

The K439 Extension cable end with the socket pin

connector connects to the mating K432 cable end (or

next K439 Extension cable end). The electrode

cables are connected using the bolt and nut provided

with the K439 Extension. Properly insulate the bolted

connection with electrical tape.

K624-1 42V REMOTE OUTPUT CONTROL

MODULE

(For use with K625, K626, K627 Remote

Control Cable)

The Module includes a 42V Remote PC board and

control cable receptacle which mount and connect

inside the LN-25 control box per the Installation

Instructions (M17253) included with the kit.

NOTE: If the K624-1 42V Remote Output Control

Module is installed but the LN-25 is to be used

without the K625, K626 or K627 Remote Control

Cable Assembly, then the Remote Board harness

plug must be removed from the 16-pin receptacle on

the Control Board and the jumper plug (T13498-21)

reinstalled.

K625, K626, K627 REMOTE CONTROL CABLE

ASSEMBLY

(Requires K624-1 Remote Output Control Module

installed in LN-25.)

The K625, K626, K627 control cable assem-

blies include an electrode cable and a 8-conductor

control cable:

1 2 ... 19 20 21 22 23 24 25 26 27 28 29 ... 39 40
