kill.  
3.a. The electrode and work (or ground) circuits  
are electrically “hot” when the welder is on.  
Do not touch these “hot” parts with your bare  
skin or wet clothing. Wear dry, hole-free  
gloves to insulate hands.  
4.b. Use suitable clothing made from durable flame-resistant  
material to protect your skin and that of your helpers from  
the arc rays.  
3.b. Insulate yourself from work and ground using dry insulation.  
Make certain the insulation is large enough to cover your full  
area of physical contact with work and ground.  
4.c. Protect other nearby personnel with suitable, non-flammable  
screening and/or warn them not to watch the arc nor expose  
themselves to the arc rays or to hot spatter or metal.  
In addition to the normal safety precautions, if welding  
must be performed under electrically hazardous  
conditions (in damp locations or while wearing wet  
clothing; on metal structures such as floors, gratings or  
scaffolds; when in cramped positions such as sitting,  
kneeling or lying, if there is a high risk of unavoidable or  
accidental contact with the workpiece or ground) use  
the following equipment:  
FUMES AND GASES  
can be dangerous.  
5.a. Welding may produce fumes and gases  
hazardous to health. Avoid breathing these

fumes and gases. When welding, keep  
your head out of the fume. Use enough  
ventilation and/or exhaust at the arc to keep

fumes and gases away from the breathing zone. When  
welding with electrodes which require special  
ventilation such as stainless or hard facing (see  
instructions on container or MSDS) or on lead or  
cadmium plated steel and other metals or coatings  
which produce highly toxic fumes, keep exposure as  
low as possible and within applicable OSHA PEL and  
ACGIH TLV limits using local exhaust or mechanical  
ventilation. In confined spaces or in some circum-  
stances, outdoors, a respirator may be required.  
Additional precautions are also required when welding  
on galvanized steel.  
3.c. In semiautomatic or automatic wire welding, the electrode,  
electrode reel, welding head, nozzle or semiautomatic  
welding gun are also electrically “hot”.  
3.d. Always be sure the work cable makes a good electrical  
connection with the metal being welded. The connection  
should be as close as possible to the area being welded.  
3.e. Ground the work or metal to be welded to a good electrical  
(earth) ground.  
3.f. Maintain the electrode holder, work clamp, welding cable and  
welding machine in good, safe operating condition. Replace  
damaged insulation.  
5. b. The operation of welding fume control equipment is affected  
by various factors including proper use and positioning of  
the equipment, maintenance of the equipment and the spe-  
cific welding procedure and application involved. Worker  
exposure level should be checked upon installation and  
periodically thereafter to be certain it is within applicable  
OSHA PEL and ACGIH TLV limits.  
3.g. Never dip the electrode in water for cooling.  
3.h. Never simultaneously touch electrically “hot” parts of  
electrode holders connected to two welders because voltage  
between the two can be the total of the open circuit voltage  
of both welders.  
5.c. Do not weld in locations near chlorinated hydrocarbon vapors  
coming from degreasing, cleaning or spraying operations.  
The heat and rays of the arc can react with solvent vapors to  
form phosgene, a highly toxic gas, and other irritating prod-  
ucts.  
3.i. When working above floor level, use a safety belt to protect  
yourself from a fall should you get a shock.  
3.j. Also see Items 6.c. and 8.  
5.d. Shielding gases used for arc welding can displace air and  
cause injury or death. Always use enough ventilation,  
especially in confined areas, to insure breathing air is safe.  
5.e. Read and understand the manufacturer’s instructions for this  
equipment and the consumables to be used, including the  
material safety data sheet (MSDS) and follow your  
employer’s safety practices. MSDS forms are available from  
your welding distributor or from the manufacturer.

pressure used. All hoses, fittings, etc. should be suitable for  
the application and maintained in good condition.  
7.b. Always keep cylinders in an upright position securely  
chained to an undercarriage or fixed support.  
6.b. Where compressed gases are to be used at the job site,  
special precautions should be used to prevent hazardous  
situations. Refer to “Safety in Welding and Cutting” (ANSI  
Standard Z49.1) and the operating information for the  
equipment being used.  
7.c. Cylinders should be located:  
• Away from areas where they may be struck or subjected to  
physical damage.  
• A safe distance from arc welding or cutting operations and  
any other source of heat, sparks, or flame.  
6.c. When not welding, make certain no part of the electrode  
circuit is touching the work or ground. Accidental contact  
can cause overheating and create a fire hazard.  
7.d. Never allow the electrode, electrode holder or any other  
electrically “hot” parts to touch a cylinder.  
6.d. Do not heat, cut or weld tanks, drums or containers until the  
proper steps have been taken to insure that such procedures  
will not cause flammable or toxic vapors from substances  
inside. They can cause an explosion even though they have  
been “cleaned”. For information, purchase “Recommended  
Safe Practices for the Preparation for Welding and Cutting of  
Containers and Piping That Have Held Hazardous  
Substances”, AWS F4.1 from the American Welding Society  
(see address above).  
7.e. Keep your head and face away from the cylinder valve outlet  
when opening the cylinder valve.  
7.f. Valve protection caps should always be in place and hand  
tight except when the cylinder is in use or connected for  
use.  
7.g. Read and follow the instructions on compressed gas  
cylinders, associated equipment, and CGA publication P-l,  
“Precautions for Safe Handling of Compressed Gases in  
Cylinders,” available from the Compressed Gas Association  
1235 Jefferson Davis Highway, Arlington, VA 22202.  
6.e. Vent hollow castings or containers before heating, cutting or  
welding. They may explode.  
6.f. Sparks and spatter are thrown from the welding arc. Wear oil  
free protective garments such as leather gloves, heavy shirt,  
cuffless trousers, high shoes and a cap over your hair. Wear  
ear plugs when welding out of position or in confined places.  
Always wear safety glasses with side shields when in a  
welding area.  
FOR ELECTRICALLY  
powered equipment.  
8.a. Turn off input power using the disconnect  
switch at the fuse box before working on  
the equipment.  
6.g. Connect the work cable to the work as close to the welding  
area as practical. Work cables connected to the building  
framework or other locations away from the welding area  
increase the possibility of the welding current passing  
through lifting chains, crane cables or other alternate cir-  
cuits. This can create fire hazards or overheat lifting chains  
or cables until they fail.  
8.b. Install equipment in accordance with the U.S. National  
Electrical Code, all local codes and the manufacturer’s  
recommendations.  
8.c. Ground the equipment in accordance with the U.S. National  
Electrical Code and the manufacturer’s recommendations.  
6.h. Also see item 1.c.  
6.I. Read and follow NFPA 51B “ Standard for Fire Prevention  
During Welding, Cutting and Other Hot Work”, available  
from NFPA, 1 Batterymarch Park, PO box 9101, Quincy, Ma  
022690-9101.  
6.j. Do not use a welding power source for pipe thawing.

SAFETY  
PRÉCAUTIONS DE SÛRETÉ  
6. Eloigner les matériaux inflammables ou les recouvrir afin de  
prévenir tout risque d’incendie dû aux étincelles.  
Pour votre propre protection lire et observer toutes les instructions  
et les précautions de sûreté specifiques qui parraissent dans ce  
manuel aussi bien que les précautions de sûreté générales suiv-  
antes:  
7. Quand on ne soude pas, poser la pince à une endroit isolé de  
la masse. Un court-circuit accidental peut provoquer un  
échauffement et un risque d’incendie.  
Sûreté Pour Soudage A L’Arc  
8. S’assurer que la masse est connectée le plus prés possible  
de la zone de travail qu’il est pratique de le faire. Si on place  
la masse sur la charpente de la construction ou d’autres  
endroits éloignés de la zone de travail, on augmente le risque  
de voir passer le courant de soudage par les chaines de lev-  
age, câbles de grue, ou autres circuits. Cela peut provoquer  
des risques d’incendie ou d’echauffement des chaines et des  
câbles jusqu’à ce qu’ils se rompent.  
1. Protegez-vous contre la secousse électrique:  
a. Les circuits à l’électrode et à la piéce sont sous tension  
quand la machine à souder est en marche. Eviter toujours  
tout contact entre les parties sous tension et la peau nue  
ou les vétements mouillés. Porter des gants secs et sans  
trous pour isoler les mains.  
b. Faire trés attention de bien s’isoler de la masse quand on  
soude dans des endroits humides, ou sur un plancher  
metallique ou des grilles metalliques, principalement dans  
les positions assis ou couché pour lesquelles une grande  
partie du corps peut être en contact avec la masse.  
c. Maintenir le porte-électrode, la pince de masse, le câble  
de soudage et la machine à souder en bon et sûr état  
defonctionnement.  
9. Assurer une ventilation suffisante dans la zone de soudage.  
Ceci est particuliérement important pour le soudage de tôles  
galvanisées plombées, ou cadmiées ou tout autre métal qui  
produit des fumeés toxiques.  
10. Ne pas souder en présence de vapeurs de chlore provenant  
d’opérations de dégraissage, nettoyage ou pistolage. La  
chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs  
du solvant pour produire du phosgéne (gas fortement toxique)  
ou autres produits irritants.  
d.Ne jamais plonger le porte-électrode dans l’eau pour le  
refroidir.  
e. Ne jamais toucher simultanément les parties sous tension  
des porte-électrodes connectés à deux machines à souder  
parce que la tension entre les deux pinces peut être le  
total de la tension à vide des deux machines.  
11. Pour obtenir de plus amples renseignements sur la sûreté,  
voir le code “Code for safety in welding and cutting” CSA  
Standard W 117.2-1974.  
f. Si on utilise la machine à souder comme une source de  
courant pour soudage semi-automatique, ces precautions  
pour le porte-électrode s’applicuent aussi au pistolet de  
soudage.  
PRÉCAUTIONS DE SÛRETÉ POUR  
LES MACHINES À SOUDER À  
TRANSFORMATEUR ET À  
REDRESSEUR  
2. Dans le cas de travail au dessus du niveau du sol, se protéger  
contre les chutes dans le cas ou on recoit un choc. Ne jamais  
enrouler le câble-électrode autour de n’importe quelle partie  
du corps.  
3. Un coup d’arc peut être plus sévère qu’un coup de soliel,  
donc:  
1. Relier à la terre le chassis du poste conformement au code de  
l’électricité et aux recommendations du fabricant. Le dispositif  
de montage ou la piece à souder doit être branché à une  
bonne mise à la terre.  
a. Utiliser un bon masque avec un verre filtrant approprié  
ainsi qu’un verre blanc afin de se protéger les yeux du ray-  
onnement de l’arc et des projections quand on soude ou  
quand on regarde l’arc.  
2. Autant que possible, I’installation et l’entretien du poste seront  
effectués par un électricien qualifié.  
b. Porter des vêtements convenables afin de protéger la  
peau de soudeur et des aides contre le rayonnement de  
l‘arc.  
3. Avant de faires des travaux à l’interieur de poste, la debranch-  
er à l’interrupteur à la boite de fusibles.  
c. Protéger l’autre personnel travaillant à proximité au  
soudage à l’aide d’écrans appropriés et non-inflammables.  
4. Garder tous les couvercles et dispositifs de sûreté à leur  
place.  
4. Des gouttes de laitier en fusion sont émises de l’arc de  
soudage. Se protéger avec des vêtements de protection libres  
de l’huile, tels que les gants en cuir, chemise épaisse, pan-  
talons sans revers, et chaussures montantes.  
5. Toujours porter des lunettes de sécurité dans la zone de  
soudage. Utiliser des lunettes avec écrans lateraux dans les  
zones où l’on pique le laitier.

SAFETY PRECAUTIONS  
WARNING  
LOADING THE WIRE REEL  
ELECTRIC SHOCK can kill.  
• Do not touch electrically live parts  
such as output terminals or internal  
wiring.  
(For machines that have code numbers Lower  
than 11383.)  
• When inching with gun trigger, electrode and  
drive mechanism are “hot” to work and ground  
and could remain energized several seconds  
after the gun trigger is released.  
Lay the LN™-23P flat with the wire reel cover up,  
unclip the rubber retaining strap, and remove the  
cover.  
Remove the center clamping nut and the cover plate  
from the wire reel.  
Unpack the 14-pound coil of wire. Be sure not to  
bend the side tangs of the coil liner and straighten  
any tangs that may have been bent.  
Place the coil on the wire reel so the coil will unwind  
when it rotates in a clockwise direction.  
Remove the start end of the coil from its holding slot  
in the coil liner, cut off the bent end, straighten the  
first few inches and thread it through the wire feed  
conduit connected to the wire enclosure until several  
inches of electrode are exposed. Be careful not to  
release the electrode until it is through the wire feed  
conduit; otherwise, it will unwind and tangle.  
Be sure all the lower tangs of the coil liner are flush  
against the back half of the wire reel and that none  
of the upper tangs are bent in against the coil.  
Replace the reel cover plate and the center clamping  
nut.  
Replace the cover of the wire reel enclosure and clip  
the retaining strap in place.  
Pull about 2 feet of the exposed end of the electrode  
through the wire feed conduit. Slide the insulator all  
the way up on the wire feed conduit.  
Make a single, free loop in the electrode and feed  
the end into the section of wire feed conduit connect-  
ed to the gearbox. Press the gun trigger and push  
the electrode into the drive rolls. Release the elec-  
trode as soon as it is picked up by the drive rolls.  
Continue feeding electrode until the excess length is  
fed through the drive rolls. Watch the single loop and  
guide it if necessary to make certain it untwists with-  
out kinking. Do not feed electrode through the gun  
cable at this time. Slide the insulator down on wire  
feed conduit until it slips over section of conduit con-  
nected to gearbox.  
• Turn OFF input power at welding power source  
before installation or changing drive roll and/or  
guide tubes.  
• Welding power source must be connected to  
system ground per the National Electrical Code  
or any applicable local codes.  
• Only qualified personnel should perform this  
installation.

PRODUCT DESCRIPTION  
The K316L-[ ] / LN™-23P is a lightweight, portable wire feed  
unit which includes calibrated wire speed control, voltage con-  
trol, wire drive with enclosed 14 lb. wire reel, analog voltmeter  
and various input control and electrode cable lengths.  
The LN™-23P was designed specifically for Innershield pipe  
welding, but, with the proper electrode, can be utilized for gen-  
eral purpose welding.  
The feeder is designed for welding with 14 pound coils of .068  
and 5/64 Innershield self-shielding electrodes using a constant  
voltage (CV) type DC power Source. When shipped, it is inter-  
nally connected for welding with electrode negative polarity  
(DC–). Depending upon which gun and cable is used, its rating  
is either 350 amps or 250 amps at 60% duty cycle.  
The wire speed control has a calibrated dial plate with a range  
of 30 to 170 inches per minute which allows quick and easy set-  
ting of the required wire feed speed. The wire speed is not  
affected by changes in the arc voltage setting even though the  
wire feed circuit is powered by arc voltage. A two-position  
switch, mounted on the gun provides a reduced speed circuit.  
This allows selection of either the preset wire speed or 83% of  
the preset speed.  
Set the unit upright on floor, straighten the gun  
cable, press the gun trigger, and feed electrode  
though the gun and cable assembly.  
A low voltage gun trigger circuit turns both the power source  
output and wire feed on and off. The gun trigger circuit is inter-  
locked by a weld current sensing reed switch so that while weld-  
ing, the gun trigger switch does not have to be held closed. The  
welding process is stopped by pulling the gun away from the  
work. The electrode remains cold until the gun trigger is operat-  
ed again.

OPERATION  
DRIVE ROLL PRESSURE  
Loosen the insulated socket head screw on the side of  
the gun, rotate the gun nozzle to the position most  
convenient for the particular application, and retighten  
the screw.  
The drive roll pressure is pre-set at the factory for  
proper feeding. If the idle roll tension must be relieved  
temporarily, see the Maintenance Section for proper  
adjustment procedure.  
When welding, set the wire feeder on the floor or hang  
it near the work area as convenient. Place the LN™-  
23P to minimize the amount of spatter falling onto it.  
Always keep the gun cable as straight as practical  
and avoid sharp bends.  
ADJUSTING WIRE FEED SPEED AND  
VOLTAGE  
Set the wire feed as specified in the procedures using  
the calibrated dial on the back of the LN™-23P control  
box. When the reduced wire speed switch (mounted  
on the gun handle) is in Position No. 1, the wire feed  
speed will be that which is indicated on the dial. In  
Position No. 2, the wire feed speed will be 83% of the  
figure indicated on the dial.  
Be sure the electrode cable, work cable, and control  
lead are connected and the power source is on.  
Press the gun trigger to feed the electrode out of the  
gun. Use a visible stickout equal to the electrical stick-  
out specified in the procedures for the wire being  
used.  
Set the voltage by adjusting the voltage control while  
welding until the voltage specified in the procedures is  
indicated on the meter. The meter reading with the  
power source on but not welding is the open circuit  
voltage. With some power sources, this voltage may  
be significantly higher than welding voltage.  
Position the gun with the wire just off or lightly touch-  
ing the work. Press the gun trigger to start the arc.  
Once the arc is established, the gun trigger can be  
released while welding. The gun trigger interlock cir-  
cuit automatically keeps the welding process on. At  
the end of the weld, pull the gun away from the work.  
When establishing initial procedures, start with the  
voltage control set near minimum. Strike an arc on  
scrap steel. If the electrode gets hot but the arc fails to  
start, increase the voltage settings until the arc can be  
established.  
When not welding, always store the gun in the insulat-  
ed tube on the front of wire feeder.  
While welding with one feeder of a two-feeder installa-  
tion the electrode of the second feeder is “HOT”. Only  
one feeder at a time can be used for welding. Do not  
press the gun trigger of the idle feeder while the other  
feeder is being used since this can shut down the  
feeder being used for welding.  
For older Code units (9805), never set the power  
source open circuit voltage higher than 50(1) volts. The  
LN™-23P will not feed wire if the voltage is higher  
than 50(1) volts. When using these older units with a  
CV Converter or a DC-600 and inching wire (not weld-  
ing) at open circuit voltages below 20 volts or above  
25 volts, feeding may be unsteady or the wire speed  
may vary from that set on the dial. This condition does  
not exist while welding. Minimum usable arc voltage is  
14 volts.  
NOTE: For improved readability of the voltmeter in  
some applications, the voltmeter guard may be  
installed rotated end for end. This will result in the pro-  
tective bars crossing the meter face in a different loca-  
tion.  
MAKING THE WELD  
Be sure the proper contact tip for either .068" or 5/64"  
wire, as appropriate, is in the gun. The thread protec-  
tor should cover the external threads on the nozzle.

MAINTENANCE  
SAFETY PRECAUTIONS  
WARNING  
Have qualified personnel do the maintenance  
work. Turn the engine off before working inside  
the machine. In some cases, it may be  
necessary to remove safety guards to perform  
required maintenance. Remove guards only  
when necessary and replace them when the  
maintenance requiring their removal is  
complete. Always use the greatest care when  
GUN AND CABLE MAINTENANCE  
Remove spatter from tip after each ten minutes of arc  
time or as required.  
Replace worn contact tips and thread protectors as  
required.  
Replace worn spring liners in nozzles. The life of the  
spring can be doubled by rotating it 180°.  
working near moving parts.  
Clean cables after using approximately 300 pounds of  
electrode. Remove the cable from the wire feeder and  
lay it out straight on the floor. Remove the contact  
nozzle tip from the gun. Using an air hose and only  
partial pressure, gently blow out the cable from the  
gun end. (Too much pressure at the start will cause  
the dirt to form a plug.) Flex the cable over its entire  
length and again blow out the cable. Repeat this pro-  
cedure until no further dirt comes out.  
-----------------------------------------------------------------------  
ELECTRIC SHOCK can kill.  
• Do not touch electrically live parts or  
electrode with skin or wet clothing.  
• Insulate yourself from work and  
ground  
• Always wear dry insulating gloves.

See additional warning information  
throughout this operator’s manual and  
the Engine manual as well.  
Figure D.1  
-----------------------------------------------------------  
REPLACING OR REVERSING DRIVE ROLLS (See  
Figure D.1).  
Loosen idle roll tension screw (Item 1) to release pres-  
sure between idle roll and drive rolls.  
Remove hex head screw (Item 2) with a 1/2" wrench  
and remove the drive roll clamping collar (Item 3).  
Remove drive rolls from shaft.  
Wipe the drive roll surfaces clean. Then install new  
drive rolls. If reversing drive rolls, turn drive rolls over  
so unworn teeth face each other.  
Before any gun is disassembled, remove unit from the  
wire feeder or shut off the power source.  
Replace clamping collar and hex head screw.  
Tighten the idle roll tension screw until it bottoms and  
then back it out two complete turns. If feeding prob-  
lems persist, do not increase the tension. check for  
other issues such as the wire spool binding or a dirty  
or damaged gun cable  
WIRE DRIVE ASSEMBLY MAINTENANCE  
Every 500 pound s of electrode, the drive roll section  
should be inspected and cleaned out if necessary. Do  
not use a solvent for cleaning the idle roll as it may  
wash lubricant out of the bearing.  
REMOVING IDLE ROLL ASSEMBLY  
Replace drive rolls as required. Drive rolls should be  
worn on both sides before replacing. See “A” of this  
section.  
Remove the idle roll tension screw (Item 1), tension  
spring retainer (Item 4), and tension spring (Item 5).  
Pivot the idle roll assembly away from the gearbox and  
lift it off the pivot pin (Item 6).  
Check the motor brushes every six months. Replace if  
they are less than 1/4" long.  
To re-assemble, replace idle roll assembly, tension  
spring, retainer, and tension screw. Adjust the tension  
screw as described above.  
Every year examine the gear box and paint the gear  
teeth with moly-disulfide filled grease.

MAINTENANCE  
CIRCUIT PROTECTION  
NAMEPLATES  
Circuit Breaker – The 3.5 amp circuit breaker located  
on the rear of the unit normally trips only when an  
overload occurs because of excessive loading in the  
wire feed cable or a defective motor or control compo-  
nents. After allowing a few minutes for cooling, push  
the reset button and weld. If it trips again, be sure the  
gun cable is not being excessively bent, is clean, and  
is the proper size for the wire diameter being fed. If it  
still trips, look for a defective electrical component.  
Whenever routine maintenance is performed on this  
machine — or at least yearly — inspect all name-  
plates and labels for legibility. Replace those which  
are no longer clear. Refer to the parts list for the  
replacement item number.
