Lincoln Electric IM620-B manual K433 Power Source Remote BOX, K432 Remote Control Cable Assembly

C-4 ACCESSORIES C-4

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

( F o r u s e w i t h K 6 2 5 , K 6 2 6 , K 6 2 7 R e m o t e 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:
