K460-1 PULSE POWER ADAPTER KIT (For use with
K461 Pulse Power Control Cable.)(No Longer Available)
This kit enables the LN-25 to pulse weld with a Pulse
Power 500 power source above Code 9300 (or lower
Codes updated with Kit).
The kit includes a Remote PC board with output
volt age 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 (No Longer Available)
(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.
K443-2 LN-25 CONTACTOR KIT
(For Codes 10500 - 10558 only)
(Factory installed in K449-3 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 (L10923) are included with
the kit.
NOTE: The K443-2 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.

K443-3 LN-25 CONTACTOR KIT
(For Codes above 11100 only)
(Factory installed in K449-3 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 (L12319) are included with
the kit.
NOTE: The K443-3 cannot be used with K431-1 or
K624-2 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-
1 Power Source Remote Box.)
CAUTION
CAUTION
This kit can only be used with LN -25ʼs Code 10500-
10558. 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.
