Lincoln Electric IM359 LN-25 - Manual (Page 24)

LN-25
C-4
ACCESSORIES
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:
The cable assembly end with the socket pin
connector connects to the LN-25 per the Instructions
(M17253) included with the K624-1 Kit.
The cable assembly end with the male pin connector
connects to the power source per the Instructions
(M17253) included with the K624-1 kit.
