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 vent the engine exhaust fumes
outdoors.

____________________________________________________

1.c. Do not ad d 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. I n some cases it may be necessary t o 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.

___________________________________________________

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

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

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

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 within applicable OSHA PEL and
ACGIH TLV limits 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 and CUTTING
SPARKS can
cause fire or explosion.

6.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

Remember that welding sparks and hot
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.

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 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.

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.

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.

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.

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.

6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque d’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 un risque 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 ce qu’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 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.

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

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 regarde l’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’aide d’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.

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 à la terre.

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

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

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

water. The best practice is to keep the wire feeder in
a dry environment. When working outdoors in severe
wet weather, place the LN™-15 with the door facing
up.

If the work clip lead is not connected, the LN™-15 will
not operate.

The work clip lead also serves as a work sensing lead
for the LN™-15. If the work clip lead is extended by
the user beyond the standard 15' (4.6m) length, the
voltmeter reading will be lower than the actual arc
volts due to resistance in the extended lead. To mini­mize the error, the following lead size is recommend­ed for the maximum extended lengths shown.

AWG Max. Length
#14 25 ft (7.6m)
#12 50 ft (15.2m)
#10 100 ft (30.5m)

CONNECTION

The LN™-15 has an internal contactor and the elec­trode is not energized until the gun trigger is closed.
When the gun trigger is closed the wire will begin to
feed and the welding process is started.

1. Shut the welder off.

2. For electrode Positive polarity welding, connect the
electrode cable to the "+" terminal of the welder
and work cable to the "-" terminal of the welder. For
Electrode Negative welding, connect the electrode
cable to the "-" terminal of the welder and work
cable to the "+" terminal of the welder.

ELECTRODE CONNECTION

Route the electrode cable through the strain relief in
the rear of the case. Connect the electrode cable to
the LN™-15 input stud using the mounting hardware
provided. Secure the cable by tightening the strain
relief.

All domestic models are supplied with pigtail for cus­tomers that prefer to make a taped and bolted con­nection externally. CE models have a male twist con-
nector for the electrode connection.

WORK CONNECTION

Connect a work lead of sufficient size between the
proper output stud on the power source and the work.
Be sure the connection to the work makes tight metal
to metal electrical contact. Poor work lead connec­tions can result in poor welding performance.

3. Attach the work clip lead from the front of the LN™-

15 to work using the spring clip at the end of the
lead. This is a control lead to supply current to the
wire feeder motor; it does not carry welding current.

4. Set the MODE switch on the engine drive to CV-

WIRE.

5. Set the WELD TERMINALS switch to WELD TER-

MINALS ON.

6. Set the WIRE FEEDER VOLTMETER switch to

either "+" or "-" as required by the electrode polarity
being used.

7. Set the ARC CONTROL knob to "0" initially and

adjust to suit.

8. Set the IDLE switch to the AUTO position.

Important: Some older engine drives may require
the IDLE switch to be in the HIGH position for prop­er LN™-15 operation.

POWER SOURCE CONNECTION

The LN™-15 can be used with any DC welding power
source. A constant voltage power source is recom­mend; however, the LN™-15 can also be used with a
constant current power source as long as the open
circuit voltage is less than 110VDC.

GENERAL DESCRIPTION

OPERATION

DUTY CYCLE

B-2

The LN™-15 is a light weight, portable, durable semi­automatic wire feeder.

The LN™-15 accommodates spools 8" (200mm)
diameter up to 4" (100mm) wide.

The domestic feeders comes factory equipped with a
K1500-2 Magnum Tweco-compatible style #2-#4 gun
bushing. Other K1500 series gun bushings are avail­able as field installed options. European models are
factory equipped with a Fast-Mate adapter.

The wire drive is capable of operating in either a "CV"
or "CC" mode. A constant voltage (CV) power source
is recommended for flux-cored arc welding (FCAW)
and gas metal arc welding (GMAW) to obtain code
quality results. However, the LN™-15 may also be
used with a constant current (CC) power source to
obtain passable results for non-critical quality applica­tions.

The “dual procedure” mode drops the WFS to 83% of
the original set point. The voltage setting remains the
same.

The LN™-15 wire feeders are intended for semi-auto­matic use. The maximum rating of the LN™-15 is
based upon a 60% duty cycle; welding 6 minutes of
welding followed by 4 minutes of idling within a 10
minute period.

RECOMMENDED PROCESSES

The LN™-15 wire drive feeds electrode for various
processes as follows:(See Table B.1)

The Across the Arc Model is suitable for GMAW,
GMAW-Pulse and FCAW semi-automatic applications
within the rated duty cycle.

PROCESS LIMITATIONS

• The across the arc model is not recommended for
spot or stitch welding.

• The across the arc model is not recommended for
GMAW-STT, SAW, SMAW, GTAW or CAG.

EQUIPMENT LIMITATIONS

• Burn-back is adjustable from 0.0 to 0.25 seconds,
with a default of 0.00 seconds.

• The preflow time is adjustable from 0.00 to 25.0 sec­onds, with a default of 0.00 seconds.

• The postflow time is adjustable from 0.0 to 25.0 sec­onds, with a default setting of 0.0 seconds.

The Across the Arc Model is capable of operating with
Lincoln DC power sources supplying between 15VDC
and 110 VDC. Simply attach the work clip to the work
piece and then connect the LN™-15 to the electrode
cable to the power source and it is ready to weld.

An internal contactor in Across the Arc Models ener­gizes the electrode output in response to the gun trig­ger.

SHIELDING GAS CONNECTION

WARNING

2 Step Trigger

2 Step trigger operation is the most common. When
the gun trigger is pulled, the welding power source
energizes the electrode output and the wire feeder
feeds wire for welding. The power source and wire
feeder continue welding until the trigger is released.

Trigger Interlock

Trigger Interlock operation provides for operator com­fort when making long welds. When the gun trigger is
first pulled, the welding power source energizes the
output and the wire feeder feeds wire for welding.
The gun trigger is then released while the weld is
made. To stop welding, the gun trigger is pulled again,
and when it is released the welding power source out­put turns off and the wire feeder stops feeding wire.

CAUTION

If the arc goes out while welding with trigger inter­lock operation, the electrode output from the
welding power source remains energized and the
wire feeder will continue to feed wire until the gun
trigger is again pulled and then released.

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

FLOW METER

The flowmeter shows the flow rate of shielding gas
and has a valve to adjust the flow. The flow meter is
calibrated for CO2, Ar, and CO2/Ar blends. The mid­dle of the ball indicates the flow rate of shielding gas.

CYLINDER may explode if

damaged.

• Keep cylinder upright and
chained to support.

• Keep cylinder away from areas where it may be
damaged.

• Never lift welder with cylinder attached.

• Never allow welding electrode to touch cylinder.

• Keep cylinder away from welding or other live
electrical circuits.

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

WARNING

• BUILD UP OF SHIELDING GAS MAY HARM

HEALTH OR KILL.

• Shut off shielding gas supply when not in use.

• See American National Standard Z-49.1, "Safety

in Welding and Cutting” Published by the

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

Customer must provide a cylinder of shielding gas,
a pressure regulator, a flow control valve and a hose
from the flow valve to the gas inlet fitting of the
LN™-15.

Adjust the flow rate by turning the valve at the bottom
of the meter. Most weld procedures require 25-40 scfh
(11.8 - 18.9 lpm) for sufficient shielding gas coverage.
Gun angle, nozzle diameter, joint configuration and
wind conditions may effect the amount of shielding
gas required.

OPERATION

CONSTANT CURRENT OPERATION

CAUTION

( See Figure B.3)

Lincoln Electric does NOT recommend constant
current semiautomatic welding for applications
which need to meet specified weld metal chemical
or mechanical property requirements or weld
quality requirements.

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

Most semiautomatic welding processes perform better
using constant voltage power sources.

Welding codes usually do not address the power source
selection or specifically, whether the welding process is
to be operated in the constant voltage or constant current
mode. Instead, codes typically specify limitations on the
current, voltage, heat input and preheat temperature
based on the material to be welded. The intention is to
assure that proper weld material properties will develop.

B-8

If the contact tip to work distance is properly main­tained, a satisfactory operating voltage range may be
achieved, and a sound weld may result. However,
when a welder uses a longer contact tip to work dis­tance, an arc-sensing wire feeder compensates by
increasing the wire feed speed to regulate the voltage.
Even if the voltage and current remain unchanged, the
increased wire feed speed may result in a deposition
rate well beyond the specified range of the electrode.
Under these conditions, the specified weld metal prop­erties may not be achieved.

Constant voltage power sources deliver large current
surges to stabilize the arc when the electrode is short­ed or the arc length is very short. However, a constant
current power source does not provide such a
response to stabilize the arc. It may be difficult to
achieve required weld metal properties, or to achieve
the required quality of welds needed to pass nonde­structive tests, when such welds are made under con­stant current operation.

Welding is sometimes performed using constant current
power sources. The operation can be more convenient
because it may allow the use of an existing stick (SMAW)
power source and the power source can be placed at a
distant location without any provision for adjusting the
output settings.

For constant current operation, the power source is set to
deliver the specified current. The power source regulates
this current regardless of changes in the welding circuit,
including cable length, electrode diameter, wire feed
speed, contact tip to work distance, etc.

Changes in the wire feed speed (WFS) or contact tip
to work distance (CTWD) affect the arc voltage when
constant current power sources are used. Lowering
the wire feed speed raises the voltage, raising the
wire feed speed lowers the voltage. Lengthening the
contact tip to work distance raises the voltage, short­ening the contact tip to work distance lowers the volt­age.

OPERATION

SETTING ARC SENSING WIRE FEED SPEED
FOR CONSTANT CURRENT OPERATION

When using a constant current (formerly variable voltage)
power source, welding performance is im proved using arc
sensing wire feed speed (CC operation). In this wire feed
mode the wire speed increases if arc voltage increases,
and decreases if arc voltage de creases, but remains con­stant at any specific voltage level.

The LN™-15 permits accurate presetting of the desired
wire feed speed, for the desired arc voltage to be used,
by setting the Wire Feed Speed in the fol lowing manner
before welding:

a. Activate press and spin during power up and change

to the CC mode. See “Changing the CV/CC mode
or WFS units” in this Operation Section.

B-9

The wire will feed at the DESIRED IN/MIN speed when the welding
power source is set to the arc
procedure (375 in/min. at 29V for example used).

The CC wire speed setting graph is shown in TABLE B.1, giving

the Wire Speed dial setting required for the DESIRED IN/MIN
and ARC VOLTS used for the welding procedures:

OPERATION

MAKING A WELD

The serviceability of a product or structure utilizing the
LN™-15 wire feeder is and must be the sole responsi­bility of the builder/user. Many variables beyond the
control of The Lincoln Electric Company affect the
results obtained in using the LN™-15 wire feeder.
These variables include, but are not limited to, welding
procedure, plate chemistry and temperature, weld­ment design, fabrication methods and service require­ments. The available range of the LN™-15 wire feed­er may not be suitable for all applications, and the
builder/user is and must be solely responsible for
welding settings.

• Close the door on the LN™-15.

• Connect the work cable to the metal to be welded.
The work cable must make good electrical contact to
the work. The work must also be grounded as stated
in "Arc Welding Safety Precautions".

• Connect the LN™-15 electrode cable to the power
source for the polarity and process to be used.
Check that the appropriate power source settings
are made for the procedure to be used. (Refer to the
power source operating and connection instructions.)

B-10

• Place the LN™-15 conveniently near the work area
in a safe location to minimize exposure to weld spat­ter and to avoid sharp bends in the gun cable.

• Connect the LN™-15 work clip to the work.

• Be sure the proper contact tip for the wire size being
used is in the gun.

• Turn on the welding power source, as well as the
shielding gas supply (if used.)

• Cut the electrode within approximately 3/8" (10mm)
of the end of the contact tip for solid wire and within
3/4" (19mm) of the extension guide for cored wire.

• Position the electrode over the joint. The end of the
electrode should be slightly off the work.

• Lower welding helmet, close the gun trigger and
begin welding. Hold the gun so the contact tip to
work distance gives the correct electrical stickout as
required for the procedure being used.

• To stop welding, release the gun trigger and the pull
the gun away from the work.

• Load a spool of .045 (1.2mm) electrode and thread
the electrode through the wire drive.

• Adjust the wire feed speed to 300 in/min
(7.62m/min).

• Press the COLD FEED switch and measure the
actual wire feed speed with a calibrated wire feed
speed tachometer.

• The measured wire feed speed should be within 2%
of the set value.

To verify the voltage display:

• Set the welding power source and LN™-15 to a CV
procedure that gives steady "spray" transfer in the
arc.

• While a weld is being made, measure the voltage
from the feed plate to work.

• The displayed voltage on the LN™-15 should be
within 2% of the measured value.
