FOR ENGINE
powered equipment.
1.a. Turn the engine off before troubleshooting and maintenance
work unless the maintenance work requires it to be running.
____________________________________________________
1.b. Operate engines in open, well-ventilated
areas or vent the engine exhaust fumes
outdoors.
____________________________________________________
1.c. Do not add the fuel near an open flame welding arc or when the engine is running. Stop
the engine and allow it to cool before refueling to prevent spilled fuel from vaporizing on
contact with hot engine parts and igniting. Do
not spill fuel when filling tank. If fuel is spilled,
wipe it up and do not start engine until fumes
have been eliminated.
____________________________________________________
1.d. Keep all equipment safety guards, covers and devices in position and in good repair.Keep hands, hair, clothing and tools
away from V-belts, gears, fans and all other moving parts
when starting, operating or repairing equipment.
____________________________________________________
1.e. 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 working near moving
parts.
___________________________________________________
1.f. Do not put your hands near the engine fan.
Do not attempt to override the governor or
idler by pushing on the throttle control rods
while the engine is running.
1.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.
ELECTRIC AND
MAGNETIC FIELDS
may be dangerous
2.a. Electric current flowing through any conductor causes
localized Electric and Magnetic Fields (EMF). Welding
current creates EMF fields around welding cables and
welding machines
2.b. EMF fields may interfere with some pacemakers, and
welders having a pacemaker should consult their physician
before welding.
2.c. Exposure to EMF fields in welding may have other health
effects which are now not known.
2.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:
2.d.1.
Route the electrode and work cables together - Secure
them with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode and
work cables. If the electrode cable is on your right
side, the work cable should also be on your right side.

ELECTRIC SHOCK can 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.
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.
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:
• Semiautomatic DC Constant Voltage (Wire) Welder.
• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
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.
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.
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.
ARC RAYS can burn.
4.a. Use a shield with the proper filter and cover
plates to protect your eyes from sparks and
the rays of the arc when welding or observing
open arc welding. Headshield and filter lens
should conform to ANSI Z87. I standards.
4.b. Use suitable clothing made from durable flame-resistant
material to protect your skin and that of your helpers from
the arc rays.
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.
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 below Threshold Limit Values (TLV)
using local exhaust or mechanical ventilation. In
confined spaces or in some circumstances, outdoors, a
respirator may be required. Additional precautions are
also required when welding on galvanized steel.
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 specific
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.
5.c.
Do not weld in locations near chlorinated hydrocarbon
coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors
form phosgene, a highly toxic gas, and other irritating products.
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.

WELDING SPARKS can
cause fire or explosion.
6.a.
Remove fire hazards from the welding area.
If this is not possible, cover them to prevent
the welding sparks from starting a fire.
materials from welding can easily go through small cracks
and openings to adjacent areas. Avoid welding near
hydraulic lines. Have a fire extinguisher readily available.
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.
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.
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
been “cleaned”. For information, purchase “Recommended
Safe Practices for the
Containers and Piping That Have Held Hazardous
Substances”, AWS F4.1 from the American Welding Society
(see address above).
6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
Sparks and spatter are thrown from the welding arc. Wear oil
6.f.
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.
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 circuits.
This can create fire hazards or overheat lifting chains or
cables until they fail.
6.h. Also see item 1.c.
Remember that welding sparks and hot

PRÉCAUTIONS DE SÛRETÉ
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 suivantes:
Sûreté Pour Soudage A LʼArc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à lʼélectrode 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 sʼisoler 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.
d.Ne jamais plonger le porte-électrode dans lʼeau 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.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions
pour le porte-électrode sʼapplicuent aussi au pistolet de
soudage.
zones où lʼon pique le laitier.
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque dʼincendie dû aux étincelles.
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 dʼincendie.
8. Sʼassurer que la masse est connectée le plus prés possible de
la zone de travail quʼil est pratique de le faire. Si on place la
masse sur la charpente de la construction ou dʼautres endroits
éloignés de la zone de travail, on augmente le risque de voir
passer le courant de soudage par les chaines de levage,
câbles de grue, ou autres circuits. Cela peut provoquer des
risques dʼincendie ou dʼechauffement des chaines et des
câbles jusquʼà ce quʼils se rompent.
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
dʼopérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de lʼarc peuvent réagir avec les vapeurs
du solvant pour produire du phosgéne (gas fortement toxique)
ou autres produits irritants.
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.
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 nʼimporte quelle partie du
corps.
3. Un coup dʼarc peut être plus sévère quʼun coup de soliel, donc:
a. Utiliser un bon masque avec un verre filtrant approprié ainsi
quʼun verre blanc afin de se protéger les yeux du rayonnement de lʼarc et des projections quand on soude ou
quand on regarde lʼarc.
b. Porter des vêtements convenables afin de protéger la peau
de soudeur et des aides contre le rayonnement de lʻarc.
c. Protéger lʼautre personnel travaillant à proximité au
soudage à lʼaide dʼécrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de lʼarc de
soudage. Se protéger avec des vêtements de protection libres
de lʼhuile, tels que les gants en cuir, chemise épaisse, pantalons 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
PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR
1. Relier à la terre le chassis du poste conformement au code de
lʼélectricité et aux recommendations du fabricant. Le dispositif
de montage ou la piece à souder doit être branché à une
bonne mise à la terre.
2. Autant que possible, Iʼinstallation et lʼentretien du poste seront
effectués par un électricien qualifié.
3. Avant de faires des travaux à lʼinterieur de poste, la debrancher à lʼinterrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur place.

SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts
such as output terminals or internal
wiring.
• 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.
• 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 an arc voltage powered,
lightweight, portable wire feed unit which includes calibrated wire speed control, voltage control, 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 general 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 type DC power Source. When
shipped, it is internally 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 setting of the procedure 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.
A low voltage gun trigger circuit turns both the power
source output and wire feed on and off. The gun trigger
circuit is interlocked by a weld current sensing reed
switch so that while welding, 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 operated
again.
The LN-23Pvoltage control is used to adjust the power
source output. Also included is an analog voltmeter
which allows easy setting of the arc voltage at the LN23P once the arc is established.
LOADING THE WIRE REEL
• 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 connected to the gearbox. Press the gun trigger and
push the electrode into the drive rolls. Release the
electrode 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 without 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 connected to gearbox.
• Set the unit upright on floor, straighten the gun
cable, press the gun trigger, and feed electrode
through the gun and cable assembly.

DRIVE ROLL PRESSURE
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.
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.
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.
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.
NEVER set the power source open circuit voltage
higher than 50
when the voltage is higher than 50
(1)
volts. The LN-23P will not feed wire
(1)
volts.
convenient for the particular application, and retighten
the screw.
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 avoid sharp bends and keep the gun cable
as straight as practical.
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 stickout specified in the procedures for the wire being used.
Position the gun with the wire just off or lightly touching 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 circuit
automatically keeps the welding process on. At the end
of the weld, pull the gun away from the work.
When not welding, always store the gun in the insulated tube on the front of wire feeder.
While welding with one feeder of a two-feeder installation 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.

When using the CV Converter or the DC-600 and inching wire (not welding) 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 protective bars crossing the meter face in a different location.
MAKING THE WELD
Be sure the proper contact tip for either .068" or 5/64"
wire, as appropriate, is in the gun. The thread protector should cover the external threads on the nozzle.
Loosen the insulated socket head screw on the side of
the gun, rotate the gun nozzle to the position most
(1)
45 volts on DC-600.
