Installation instructions (M17590) are included with
this kit.
K460-1 PULSE POWER ADAPTER KIT
(For use with K461 Pulse Power Control Cable.)
This kit enables the LN-25 to pulse weld with a Pulse
Power 500 power source above Code 9300 (or lower
Codes updated with S18506 Kit).
The kit includes a Remote PC board with output
voltage control, and control cable receptacle which
mount and connect inside the LN-25 control box
per the Installation Instructions (L9636) included with
the kit.
NOTE: If the K460-1 Pulse Power Adapter Kit is in-
stalled but the LN-25 is to be used without the K461
Pulse Power Control Cable Assembly, then the in-
structions for returning the unit to across the arc op-
eration included with the Installation Instructions
(L9636) must be followed.
K461 PULSE POWER CONTROL CABLE
ASSEMBLY
(Requires K460-1 Pulse Power Adapter Kit installed
in LN-25.)
The K461 control cable assemblies include an elec-
trode cable, rated for up to 500 amps 60% duty
cycle, and a 9-conductor control cable. The control
cable pin connector connects to the LN-25 and the
lugged leads connect to the Pulse Power. Available
in 25, 50, 75 and 100 ft. lengths.
K443-1 LN-25 CONTACTOR KIT
(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 (L9676) are included with
the kit.
ACCESSORIES
This kit 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 cannot be used with K431-1 or
K624-1 Remote Output Control Kit or K460-1 Pulse
Power Adapter 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
per the Installation Instructions (M15324) and power
source connection diagrams included with the kit.
