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

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

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

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

SAFETY  
PRÉCAUTIONS DE SÛRETÉ  
6. Eloigner les matériaux inflammables ou les recouvrir afin de  
prévenir tout risque dʼincendie 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 dʼincendie.  
Sûreté Pour Soudage A LʼArc  
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 lev-  
age, câbles de grue, ou autres circuits. Cela peut provoquer  
des risques dʼincendie ou dʼechauffement des chaines et des  
câbles jusquʼà ce quʼils se rompent.  
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.  
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.  
PRÉCAUTIONS DE SÛRETÉ POUR  
LES MACHINES À SOUDER À  
TRANSFORMATEUR ET À  
REDRESSEUR  
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 ray-  
onnement 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.  
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 debranch-  
er à lʼinterrupteur à la boite de fusibles.  
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, pan-  
talons sans revers, et chaussures montantes.  
4. Garder tous les couvercles et dispositifs de sûreté à leur  
place.  
5. Toujours porter des lunettes de sécurité dans la zone de  
soudage. Utiliser des lunettes avec écrans lateraux dans les  
zones où lʼon pique le laitier.

SAFETY  
Electromagnetic Compatibility (EMC)  
Conformance  
Products displaying the CE mark are in conformity with European Community Council Directive of 15 Dec  
2004 on the approximation of the laws of the Member States relating to electromagnetic compatibility,  
2004/108/EC. It was manufactured in conformity with a national standard that implements a harmonized  
standard: EN 60974-10 Electromagnetic Compatibility (EMC) Product Standard for Arc Welding Equipment.  
It is for use with other Lincoln Electric equipment. It is designed for industrial and professional use.  
Introduction  
All electrical equipment generates small amounts of electromagnetic emission. Electrical emission may be  
transmitted through power lines or radiated through space, similar to a radio transmitter. When emissions  
are received by other equipment, electrical interference may result. Electrical emissions may affect many  
kinds of electrical equipment; other nearby welding equipment, radio and TV reception, numerical controlled  
machines, telephone systems, computers, etc. Be aware that interference may result and extra precautions  
may be required when a welding power source is used in a domestic establishment.  
Installation and Use  
The user is responsible for installing and using the welding equipment according to the manufacturer’s  
instructions. If electromagnetic disturbances are detected then it shall be the responsibility of the user of the  
welding equipment to resolve the situation with the technical assistance of the manufacturer. In some cases  
this remedial action may be as simple as earthing (grounding) the welding circuit, see Note. In other cases it  
could involve construction of an electromagnetic screen enclosing the power source and the work complete  
with associated input filters. In all cases electromagnetic disturbances must be reduced to the point where  
they are no longer troublesome.  
Note: The welding circuit may or may not be earthed for safety reasons according to national codes.  
Changing the earthing arrangements should only be authorized by a person who is compe-  
tent to access whether the changes will increase the risk of injury, e.g., by allowing parallel  
welding current return paths which may damage the earth circuits of other equipment.  
Assessment of Area  
Before installing welding equipment the user shall make an assessment of potential electromagnetic prob-  
lems in the surrounding area. The following shall be taken into account:  
a) other supply cables, control cables, signaling and telephone cables; above, below and adjacent to the  
welding equipment;  
b) radio and television transmitters and receivers;  
c) computer and other control equipment;  
d) safety critical equipment, e.g., guarding of industrial equipment;  
e) the health of the people around, e.g., the use of pacemakers and hearing aids;  
f) equipment used for calibration or measurement  
g) the immunity of other equipment in the environment. The user shall ensure that other equipment being  
used in the environment is compatible. This may require additional protection measures;  
h) the time of day that welding or other activities are to be carried out.

SAFETY  
Electromagnetic Compatibility (EMC)  
The size of the surrounding area to be considered will depend on the structure of the building and other  
activities that are taking place. The surrounding area may extend beyond the boundaries of the premises.  
Methods of Reducing Emissions  
Mains Supply  
Welding equipment should be connected to the mains supply according to the manufacturer’s recommenda-  
tions. If interference occurs, it may be necessary to take additional precautions such as filtering of the mains  
supply. Consideration should be given to shielding the supply cable of permanently installed welding equip-  
ment, in metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. The  
shielding should be connected to the welding power source so that good electrical contact is maintained  
between the conduit and the welding power source enclosure.  
Maintenance of the Welding Equipment  
The welding equipment should be routinely maintained according to the manufacturer’s recommendations.  
All access and service doors and covers should be closed and properly fastened when the welding equip-  
ment is in operation. The welding equipment should not be modified in any way except for those changes  
and adjustments covered in the manufacturers instructions. In particular, the spark gaps of arc striking and  
stabilizing devices should be adjusted and maintained according to the manufacturer’s recommendations.  
Welding Cables  
The welding cables should be kept as short as possible and should be positioned close together, running at  
or close to floor level.  
Equipotential Bonding  
Bonding of all metallic components in the welding installation and adjacent to it should be considered.  
However, metallic components bonded to the work piece will increase the risk that the operator could  
receive a shock by touching these metallic components and the electrode at the same time. The operator  
should be insulated from all such bonded metallic components.  
Earthing of the Workpiece  
Where the workpiece is not bonded to earth for electrical safety, not connected to earth because of its size  
and position, e.g., ships hull or building steelwork, a connection bonding the workpiece to earth may reduce  
emissions in some, but not all instances. Care should be taken to prevent the earthing of the workpiece  
increasing the risk of injury to users, or damage to other electrical equipment. Where necessary, the connec-  
tion of the workpiece to earth should be made by a direct connection to the workpiece, but in some countries  
where direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected  
according to national regulations.  
Screening and Shielding  
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate prob-  
lems of interference. Screening of the entire welding installation may be considered for special

voltages less than 110 VDC.  
WELD CABLE SIZE  
------------------------------------------------------------------------  
Table A.1 located below are copper cable sizes rec-  
ommended for different currents and duty cycles.  
Lengths stipulated are the distance from the welder to  
work and back to the welder again. Cable sizes are  
increased for greater lengths primarily for the purpose  
of minimizing cable drop.  
LOCATION  
For best wire feeding performance, place the LN-  
25™ IRONWORKER on a stable and dry surface.  
Keep the wire feeder in a vertical position. Do not  
operate the wire feeder on an angled surface of  
more than 15 degrees.  
Do not submerge the LN-25™ IRONWORKER.  
The LN-25™ IRONWORKER is rated IP23 and is  
suitable for outdoor use.

Install the shielding gas supply as follows:  
1. Secure the cylinder to prevent it from falling.  
2. Remove the cylinder cap. Inspect the cylinder valves  
and regulator for damaged threads, dirt, dust, oil or  
grease. Remove dust and dirt with a clean cloth. DO  
NOT ATTACH THE REGULATOR IF OIL, GREASE  
OR DAMAGE IS PRESENT! Inform your gas supplier  
of this condition. Oil or grease in the presence of high  
pressure oxygen is explosive.  
3. Stand to one side away from the outlet and open the  
cylinder valve for an instant. This blows away any dust  
or dirt which may have accumulated in the valve out-  
let.  
4. Attach the flow regulator to the cylinder valve and  
tighten the union nut(s) securely with a wrench. Note:  
if connecting to 100% CO cylinder, insert regulator  
2
adapter between regulator and cylinder valve. If  
adapter is equipped with a plastic washer, be sure it is  
seated for connection to the CO cylinder.

5. Attach one end of the inlet hose to the outlet fitting of  
the flow regulator. Attach the other end to the welding  
system shielding gas inlet. Tighten the union nuts with  
a wrench.  
6. Before opening the cylinder valve, turn the regulator  
adjusting knob counterclockwise until the adjusting  
spring pressure is released.  
7. Standing to one side, open the cylinder valve slowly a  
fraction of a turn. When the cylinder pressure gage  
stops moving, open the valve fully.  
8. The flow regulator is adjustable. Adjust it to the flow  
rate recommended for the procedure and process  
being used before making a weld.

Wire Feed Speed, CV Operation  
When Across the Arc models are operated with CV  
power sources, the wire feed speed will remain a con-  
stant value, independent of arc voltage changes, as  
along as the arc voltage does not drop below the val-  
ues per the following table.

The 83% wire feed speed reduces the wire feed  
speed to 83% of the original set value when activated.  
For example, if the original wfs = 200 in/min, the feed-  
er will regulate to 0.83 x 200 = 166 in/min.

OPERATION  
THERMAL LED, MOTOR OVERLOAD  
After Welding  
The display continues to hold the value of the amper-  
age or WFS and arc voltage for five seconds after  
welding stops. The amperage or WFS and voltage  
displays flash.  
The thermal light illuminates when the wire  
drive motor draws too much current. If the  
thermal light illuminates, the wire drive will  
automatically shutdown for up to 30 seconds to allow  
the motor to cool. To start welding again, release the  
gun trigger, inspect the gun cable, liner (and conduit).  
Clean and make repairs as necessary. Start welding  
again when the problem has been safely resolved.  
Set-Up Menu  
Before entering the set-up menu:  
Set the display to the desired wire feed speed (exam-  
ple: 400 inches per minute)  
For best results, keep the gun cable and conduit as  
straight as possible. Perform regular maintenance  
and cleaning on the gun liner, conduit and gun.  
Always use quality electrode, such as L-50 or L-56  
from Lincoln Electric.  
Measure the actual wire feed speed (example: 405  
inches per minute)  
Place the WFS knob in the 12 oʼclock position.  
To enter the set-up menu, use paper clip to press the  
POWER-UP SEQUENCE  
small button located on the case front.  
All of the LEDʼs will briefly illuminate during power-up.  
If the gun trigger is activated during power up, the  
feeder will not operate until the gun trigger is released.  
Calibration of Amperage  
Connect the feeder to a power source and grid.  
Adjust the power source and grid to the desired  
amperage. (example: 220 Amps)

OPERATION  
LEFT DISPLAY SELECTION  
AMPERAGE CALIBRATION  
The left display can show either amperage or actual  
WFS during welding. Note that actual WFS is not the  
same as preset WFS. For example, the preset WFS  
may be set to 400 ipm, but the arc voltage is only 15V.  
The actual WFS will be approximately 280 ipm  
because there is not enough arc voltage to run at 400  
ipm.  
Measurements for adjusting the Amperage calibration  
must be made before entering the set-up menu. If no  
changes are being made to the calibration, then press  
the set-up button to enter Display Hold.  
While in the set-up menu, adjust the calibration factor

OPERATION  
INTERNAL CONTROLS DESCRIPTION  
COLD FEED PUSHBUTTON  
(See Figure B.2)  
(See Figure B.2)  
When cold feeding, the wire  
drive will feed electrode but  
neither the power source nor  
the gas solenoid will be ener-  
gized. Adjust the speed of cold  
feeding by rotating the WFS  
knob. Cold feeding, or "cold  
inching" the electrode is useful  
for threading the electrode  
through the gun.  
2 Step - Trigger Interlock Switch  
The 2 Step - Trigger Interlock  
switch changes the function of the  
gun trigger. 2 Step trigger opera-  
tion turns welding on and off in  
direct response to the trigger.  
Trigger Interlock operation allows  
welding to continue when the trig-  
ger is released for comfort on long  
welds.  
Place the toggle switch in the DOWN position for 2  
Step operation or in the UP position for Trigger  
Interlock operation.  
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 com-  
fort 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 feed-  
ing wire.  
CAUTION  
If the arc goes out while welding with  
trigger interlock operation, the elec-  
trode 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.
