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 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.

ACCESSORIES

K443-3 LN-25 CONTACTOR KIT

(For Codes above 11100 only)

(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 (L12319) are included with

the kit.

NOTE: The K443-3 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.)

CAUTION

This kit can only be used with LN-25’s 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.
