WIRE DRIVE ROLLS AND GUIDE TUBES

The LN-23P is shipped with the proper drive rolls and guide tubes factory installed. Do not adjust the idle roll tension adjusting screw. If the idle roll tension must be relieved temporarily, see “A” and “B” of Maintenance Section.

OPTIONAL FEATURES INSTALLATION

INNERSHIELD GUN AND CABLE

Unclip the rubber retaining strap that holds the wire

enclosure cover in place and remove the cover.

Push the wire drive section door latch towards the

rear of LN-23P and open door.

Loosen the gun locking set screw in the conductor

 

block on the front of the gear box with a 3/16 hex

Allen wrench.

Lay the cable out straight. Insert the connector on

 

the conductor cable thru the large grommet in the

 

front of the wire drive section and into the brass

 

block on the front of the gear box. Make sure it is all

 

the way in and tighten the locking set screw with a

 

3/16 hex Allen wrench. Keep this connection clean

and bright.

Connect the 3 pin gun trigger connector to the lower

receptacle.

If the gun cable being used has a reduced speed

 

switch, connect the 4 pin reduced speed switch

 

connector to the upper receptacle. If the reduced

 

speed switch is not used, install the protective cap

 

on the upper receptacle.

K-350 ADAPTER KIT– Turn off power source and all

power to the power source.

SAM-400 Engine Welders: Attach the shock mount-

 

ed mounting plate to the front of the SAM electrical

 

component panel to left of the relay case with 4 of

 

the #10 self-tapping screws provided. Older models

 

require the drilling of 4 5/32 dia. holes into the

 

panel. Connect the adapter control cable to the

SAM terminal strips per the proper connection dia- gram.

DC-600 (below code 10500): Attach the triangular

 

mounting plate to the shock mounted plate of the

 

Adapter with three of the #10 self-tapping screws

 

provided. Attach the triangular plate to the side of

 

the DC-600 adjacent to the control terminal strips

 

using two roof screws and one front panel screw.

 

Connect the Adapter control cable to the DC-600

 

terminal strips power the proper connection dia-

gram.

Other Power Sources: Mount the Adapter Kit to the

 

side of the power source or some convenient loca-

 

tion so its control cable can be connected to the

 

power source terminal strip. Use the shock mount-

 

ed mounting plate as a template to locate the four

 

5/32" diameter holes that must be drilled in the case

 

side. (Use caution not to drill into or get chips into

 

any internal components.) Mount the Adapter Kit

 

with four of the #10 self-tapping screws provided.

 

Connect the Adapter control cable to power source

 

terminal strips per the proper connection diagram.

K350-1 ADAPTER KIT - Turn off power source and all

power to the power source.

Used to connect an LN-23P (K316L-1) to a Lincoln

power source that has a 14 pin control connector.

Mount the Adapter Kit to the side of the power

 

source or some convenient location so its control

 

cable can be connected to the power source termi-

 

nal strip. See the mounting instructions form the

K350

Connect the Adapter control cable to 14 pin con-

 

nector on the power source per the proper connec-

tion diagram.

Connect a 12 AWG or larger rubber covered flexible

 

lead physically suitable for the installation to the

 

voltage sensing work lead (#21) coming from the

 

LN23P control cable connector. For convenience,

 

wrap this voltage sensing lead around the work lead

 

and tape in place. Connect it directly to the work or

 

to the work cable connection

K-276 ENCLOSED 50lb.WIRE REEL SUPPORT Installation and loading instructions (M-13153) are supplied with the kit.
