The Above For Gasoline Engines

i

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 ventthe 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 fumeshave 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 engineis 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 arenow 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 tapewhen 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. Ifthe electrode cable is on your right
side, the work cable should also be on your right side.

___________________________________________________

1.g. To prevent accidentally starting gasolineengines while
turning the engine or welding generator during maintenance
work, disconnect the spark plug wires, distributor cap or
magneto wire asappropriate.

2.d.4. Connect the work cable to the workpiece as close as
possible to thearea being welded.

2.d.5. Do not work next to welding power source.

ELE CTRIC SHOC K 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-f ree

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
mu s t be pe r for m ed un d er el e ctr i cal l y haz a rdou s
con ditions (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,
elect rode reel, weldin g head, n ozzle or semiauto matic
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 simultan eo usly t ouch e lectric al ly “ ho t” p ar ts o f
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 prod uce fumes and gases
hazardous to health. Avoid breathing these
fumes and gas es. 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

ventilation. In confined s pa ce s or in so me circum­st a nce s, ou t doo r s, a r e spi rato r may b e req u ire d.
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

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 L’Arc

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 isolerles 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 desgrilles metalliques, principalement dans
les positions assis ou couché pour lesquelles une grande
partie du corpspeut 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 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 latension 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 s’applicuent aussi au pistolet de
soudage.

6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risqued’incendie 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 unrisque d’incendie.

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 lev­age, câbles de grue, ou autres circuits. Cela peut provoquer
des risques d’incendie ou d’echauffement des chaines et des
câbles jusqu’à cequ’ils 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 fumeéstoxiques.

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 produitsirritants.

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.

PRÉCAUTIONS DE SÛRETÉ POUR

2. Dans lecas de travail au dessus du niveau du sol, seprotéger
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:

a. Utiliser un bon masque avec un verre filtrant approprié

ainsi qu’un verre blanc afin de se protéger les yeux du ray­onnement de l’arc et des projections quand on soude ou
quand on regardel’arc.

b. Porter des vêtements convenables afin de protéger la

peau de soudeur et des aides contre le rayonnement de
l‘arc.

c. Protéger l’autre personnel travaillant à proximité au

soudage à l’aided’écrans appropriés et non-inflammables.

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, 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
zones où l’onpique le laitier.

LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR

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 àla terre.

2. Autant que possible, I’installation et l’entretien du poste seront
effectués par unélectricien qualifié.

3. Avant de faires des travaux à l’interieur de poste, la debranch­er à l’interrupteurà la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

SAFETY PRECAUTIONS

WARNING

OPERATION

The LN™-23P includes a voltage control which con­trols the power source output. Also included is an ana­log voltmeter which allows easy setting of the proce­dure arc voltage at the LN™-23P.

B-1

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 a 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 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 and 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,
which is mounted on the gun and a reduced speed cir­cuit, allows selection of 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.

LOADING THE WIRE REEL

(For machines that have code numbers Lower
than 11383.)

• 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 may 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 plat 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 cable at this time. Slide 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
though the gun and cable assembly.

DRIVE ROLL PRESSURE

• Do not adjust the drive roll pressure. If the idle roll
tension must be relieved temporarily, see
(Maintenance Section).

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 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.

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 strikeout equal to the electrical
strikeout 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 screw on the side of the gun,
rotate the gun nozzle to the position most convenient
for the particular application, and retighten the insulat­ed screw.

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
working near moving parts.

------------------------------------------------------------------------

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 drawing below.)

Loosen idle roll tension screw (Item 1) to release pres­sure 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).

REMOVING IDLE ROLL ASSEMBLY

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).

To re-assemble, replace idle roll assembly, tension
spring, retainer, and tension screw. Tighten the ten­sion screw until it bottoms, and then back it out two
complete turns.

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°.

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 pro­cedure until no further dirt comes out.

Remove drive rolls from shaft.
Wipe the drive roll surfaces clean. Then install drive
rolls. If reversing drive rolls, turn drive rolls over so
unworn teeth face each other.

Replace clamping collar and hex head screw.
Tighten the idle roll tension screw until it bottoms and

then back it out two complete turns.

LN™-23P

Before any gun is disassembled, remove unit from the
wire feeder or shut off the power source.

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.

Replace drive rolls as required. Drive rolls should be
worn on both sides before replacing. See “A” of this
section.

Check the motor brushes every six months. Replace if
they are less than 1/4" long.

Every year examine the gear box and paint the gear
teeth with moly-disulfide filled grease.

MAINTENANCE

D-2

CIRCUIT PROTECTION

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 compo­nents. 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.

NAMEPLATES

Whenever routine maintenance is performed on this
machine — or at least yearly — inspect all name­plates and labels for legibility. Replace those which
are no longer clear. Refer to the parts list for the
replacement item number.
