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. 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.

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.

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.

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.
POWER SOURCE
