K439 REMOTE EXTENSION CABLE
ASSEMBLY
The 50 ft. Extension cable assemblies are used to ex -
tend 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 con -
nector 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 con -
nection with electrical tape.
K624-1 42V REMOTE OUTPUT
CONTROL MODULE
( Fo 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 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 assemblies
include an electrode cable and a 8-conductor control
cable:

with the K624-1 Kit.
The cable assembly end with the male pin connector
connects to the power source per the Instructions
included with the K624- 1 kit.
K444, K444-1 OR K444-2 REMOTE
VOLTAGE CONTROL KIT
(Not required if using K431-1 or K624-1 Remote
Output Control Kit.
The Remote Voltage Control Kit provides remote (10K
ohm rheostat) control of power source output arc
voltage level.
K444 connects to power sources with control terminal
strip connections for lead numbers 75, 76 and 77.
K444-1 connects to power sources with a 6-pin control
receptacle.
NOTE: To use a K444-1 with power sources with only
a 14-pin control receptacle, a K864 Adapter is required
to connect to K444-1 and if using a power source
without an output control switch, a K484 Jumper Plug
will also be required to jumper the output pilot circuit
(2-4).
K444-2 connects to power sources with a 14-pin
control receptacle and provides a 2-4 jumper to
activate power source output.
Installation Instructions are included with the kit.
K577-1 REAR HANDLE KIT
(For LN-25™ model codes above 9383)
The fold-down handle mounts to the rear of the LN 25
case per the Installation Instructions (M16567)
shipped with the kit.
This handle provides a means to also carry the LN 25
in the vertical position, especially convenient for
passing the unit through a manhole.
