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

fumes and gases 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.

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.

SAFETY  
PRÉCAUTIONS DE SÛRETÉ  
6. Eloigner les matériaux inflammables ou les recouvrir afin de  
prévenir tout risque d’incendie dû aux étincelles.  
Pour votre propre protection lire et observer toutes les instructions  
et les précautions de sûreté specifiques qui parraissent dans ce  
manuel aussi bien que les précautions de sûreté générales suiv-  
antes:  
7. Quand on ne soude pas, poser la pince à une endroit isolé de  
la masse. Un court-circuit accidental peut provoquer un  
échauffement et un risque d’incendie.  
Sûreté Pour Soudage A L’Arc  
8. S’assurer que la masse est connectée le plus prés possible  
de la zone de travail qu’il est pratique de le faire. Si on place  
la masse sur la charpente de la construction ou d’autres  
endroits éloignés de la zone de travail, on augmente le risque  
de voir passer le courant de soudage par les chaines de lev-  
age, câbles de grue, ou autres circuits. Cela peut provoquer  
des risques d’incendie ou d’echauffement des chaines et des  
câbles jusqu’à ce qu’ils se rompent.  
1. Protegez-vous contre la secousse électrique:  
a. Les circuits à l’électrode et à la piéce sont sous tension  
quand la machine à souder est en marche. Eviter toujours  
tout contact entre les parties sous tension et la peau nue  
ou les vétements mouillés. Porter des gants secs et sans  
trous pour isoler les mains.  
b. Faire trés attention de bien s’isoler de la masse quand on  
soude dans des endroits humides, ou sur un plancher  
metallique ou des grilles metalliques, principalement dans  
les positions assis ou couché pour lesquelles une grande  
partie du corps peut être en contact avec la masse.  
c. Maintenir le porte-électrode, la pince de masse, le câble  
de soudage et la machine à souder en bon et sûr état  
defonctionnement.  
9. Assurer une ventilation suffisante dans la zone de soudage.  
Ceci est particuliérement important pour le soudage de tôles  
galvanisées plombées, ou cadmiées ou tout autre métal qui  
produit des fumeés toxiques.  
10. Ne pas souder en présence de vapeurs de chlore provenant  
d’opérations de dégraissage, nettoyage ou pistolage. La  
chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs  
du solvant pour produire du phosgéne (gas fortement toxique)  
ou autres produits irritants.  
d.Ne jamais plonger le porte-électrode dans l’eau pour le  
refroidir.  
e. Ne jamais toucher simultanément les parties sous tension  
des porte-électrodes connectés à deux machines à souder  
parce que la tension entre les deux pinces peut être le  
total de la tension à vide des deux machines.  
11. Pour obtenir de plus amples renseignements sur la sûreté, voir  
le code “Code for safety in welding and cutting” CSA Standard  
W 117.2-1974.  
f. Si on utilise la machine à souder comme une source de  
courant pour soudage semi-automatique, ces precautions  
pour le porte-électrode s’applicuent aussi au pistolet de  
soudage.  
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.  
PRÉCAUTIONS DE SÛRETÉ POUR  
LES MACHINES À SOUDER À  
TRANSFORMATEUR ET À  
REDRESSEUR  
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 ray-  
onnement de l’arc et des projections quand on soude ou  
quand on regarde l’arc.  
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.  
b. Porter des vêtements convenables afin de protéger la  
peau de soudeur et des aides contre le rayonnement de  
l‘arc.  
2. Autant que possible, I’installation et l’entretien du poste seront  
effectués par un électricien qualifié.  
c. Protéger l’autre personnel travaillant à proximité au  
soudage à l’aide d’écrans appropriés et non-inflammables.  
3. Avant de faires des travaux à l’interieur de poste, la debranch-  
er à l’interrupteur à la boite de fusibles.  
4. Des gouttes de laitier en fusion sont émises de l’arc de  
soudage. Se protéger avec des vêtements de protection libres  
de l’huile, tels que les gants en cuir, chemise épaisse, pan-  
talons sans revers, et chaussures montantes.  
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 l’on pique le laitier.

SAFETY  
Electromagnetic Compatibility (EMC)  
Conformance  
Products displaying the CE mark are in conformity with European Community Council Directive of 3 May  
1989 on the approximation of the laws of the Member States relating to electromagnetic compatibility  
(89/336/EEC). 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 applications.

OPERATION  
This figure closely resembles what is actually seen  
during welding. The “arc stream’’ is seen in the middle  
of the figure. This is the electric arc created by the  
electric current flowing through the space between the  
end of the electrode and the work.  
STICK-WELDING CIRCUIT  
(See Figure B.3)  
FIGURE B.3  
The temperature of this arc is about 6000°F (3315°C),  
which is more than enough to melt metal. The arc is  
very bright, as well as hot, and cannot be looked at  
with the naked eye without risking painful injury. A very  
dark lens, specifically designed for arc welding, must  
be used with a hand or face shield whenever viewing  
the arc. The arc melts the base metal and actually  
digs into it, much as water through a nozzle on a gar-  
den hose digs into the earth. The molten metal forms  
a pool or crater and tends to flow away from the arc.  
As it moves away from the arc, it cools and solidifies.  
A slag forms on top of the weld to protect it during  
cooling.  
Current flows through the electrode cable and elec-  
trode holder to the electrode and across the arc. On  
the work side of the arc, the current flows through the  
base metal to the work cable and back to the welding  
machine. The circuit must be complete for the current  
to flow.  
The function of the covered electrode is much more  
than simply to carry current to the arc. The electrode  
is composed of a core rod of metal with an extruded  
chemical covering. The core rod melts in the arc and  
tiny droplets of molten metal shoot across the arc into  
the molten pool. The electrode provides additional  
filler metal for the joint to fill the groove or gap  
between the two pieces of the base metal. The cover-  
ing also melts or burns in the arc. It has several func-  
tions. It makes the arc steadier, provides a shield of  
smoke-like gas around the arc to keep oxygen and  
nitrogen in the air away from the molten metal, and  
provides a flux for the molten pool. The flux picks up  
impurities and forms the protective slag.  
To weld, the work clamp must be tightly connected to  
clean base metal. Remove paint, rust, etc. as neces-  
sary to get a good connection. Connect the work  
clamp as close as possible to the area you wish to  
weld. Avoid allowing the welding circuit to pass  
through hinges, bearings, electronic components or  
similar devices that can be damaged.  
An electric arc is made between the work and the end  
of a small metal rod, the electrode, which is clamped  
in a holder and the holder is held by the person doing  
the welding. A gap is made in the welding circuit (see  
Figure B.3) by holding the tip of the electrode 1/16-  
1/8” away from the work or base metal being welded.  
The electric arc is established in this gap and is held  
and moved along the joint to be welded, melting the  
metal as it is moved.  
MAKING A WELD  
Insert the bare part of the electrode into the electrode  
holder jaws and connect the work clamp to the weld-  
ing piece. Make sure to have good electrical contact.  
1. Turn the welder on.  
2. Lower your welding helmet to protect your face and  
eyes.  
3. Strike the electrode at the work point on the work-  
piece as if striking a match. Do not hit the electrode  
on the workpiece, which will damage the stick elec-  
trode and make striking an arc difficult. Scratch the  
electrode slowly over the metal and you will see  
sparks. While scratching, lift the electrode 1/8"  
(3.2mm) and the arc will establish.  
ELECTRIC ARC (Stick-Welding)  
(See Figure B.4)  
Action that takes place in the electric arc.  
FIGURE B.4  
NOTE: If you stop moving the electrode while scratch-  
ing, the electrode will stick.  
NOTE: Most beginners try to strike the arc by a fast  
jabbing motion down on the plate. Result:  
They either stick or their motion is so fast that  
they break the arc immediately.

OPERATION  
8. Turn the machine off and remove the stub by open-  
ing the jaws of the electrode holder and insert a  
new electrode.  
Note: The welded work piece and electrode stub are  
hot after welding. Allow them to cool down  
before touching or use pliers to move. Always  
make sure the welder is turned off before set-  
ting down the Electrode Holder.  
4. Immediately after striking the arc try to maintain a  
distance from the workpiece that is equivalent to  
the diameter of the electrode used. Maintain this  
distance as constantly as possible during the weld.  
Whenever possible, weld from left to right (if right-  
handed). Hold the electrode at a slight angle as  
shown. (See Figure B.5)  
FIGURE B.5  
TIG Welding (Tungsten Inert Gas Welding)  
This machine is capable of direct current (DC) TIG  
welding which is suitable for hard metals such as  
steel, stainless steel, copper & brass. The TIG  
process is good for welding thin materials requiring  
very good cosmetic appearance with low heat input  
and low spatter. TIG welding uses a tungsten elec-  
trode which delivers electrical current to the work  
piece by way of an electric arc. Unlike stick welding in  
which the electrode is consumed in the arc, the tung-  
sten electrode is not consumed. Instead filler metal is  
added to the weld by manually dipping a filler rod into  
the weld puddle. TIG welding requires a higher skill  
level than stick welding and practice is required to  
master the technique. For best results a TIG welding  
class is suggested or obtaining a book on how to TIG  
weld.  
5. As the electrode burns off the electrode must be fed  
to the work to maintain correct arc length. The easi-  
est way to tell whether the arc has the correct  
length is by listening to its sound. A nice, short arc  
has a distinctive, “crackling” sound, very much like  
eggs frying in a pan. The incorrect, long arc has a  
hollow, blowing or hissing sound.  
6. The important thing to watch while welding is the  
puddle of molten metal right behind the arc. Do  
NOT watch the arc itself. It is the appearance of the  
puddle and the ridge where the molten puddle  
solidifies that indicate correct welding speed. The  
ridge should be approximately 3/8" (9.5mm) behind  
the electrode. (See Figure B.6)  
TIG welding also requires 100% Argon shielding gas  
to shield the arc, preventing porosity in the weld. This  
is different than stick welding which has a coating on  
the electrode to produce its own shielding. In addi-  
tion, a gas regulator, a manual gas valve TIG torch,  
torch parts kit, torch adapter and filler metal are  
required. Refer to the accessories section of this  
manual for an appropriate optional TIG torch, parts kit  
and torch adapter. A gas regulator, filler metal and a  
bottle of shielding gas are readily available from a  
welding gas distributor.  
FIGURE B.6  
Figure B.7 shows the basic TIG welding set-up:  
FIGURE B.7  
GAS BOTTLE  
WITH REGULATOR  
Most beginners tend to weld too fast, resulting in a  
thin, uneven, “wormy” looking bead. They are not  
watching the molten metal.  
IMPORTANT: For general welding it is not necessary  
to weave the arc; neither forwards and backwards nor  
sideways. Weld along at a steady pace. You will find it  
easier.  
TIG TORCH  
ADAPTER  
NOTE: When welding on thin plate, you will find that  
you will have to increase the welding speed, whereas  
when welding on heavy plate, it is necessary to go  
more slowly in order to get good penetration.

OPERATION  
Making a TIG Weld:  
1. Connect the work cable to the positive “+” output  
terminal.  
2. Connect the TIG torch to the negative “-“ output ter-  
minal.  
3. Connect the gas line from the TIG torch adapter to  
the gas regulator connected to the gas bottle.  
4. Open the gas valve on the gas bottle and adjust the  
gas regulator to approximately 20-30 cfm.  
5. Set the amperage based on material thickness:

(3/16) 4.8mm  
Amperage Setting  
60-90 Amps  
75-120 Amps  
125-150 Amps  
6. Turn machine on.  
7. Turn the gas valve on the torch to start shielding  
gas flowing.  
8. Touch the tungsten to the work piece and pause for  
a second.  
9. Slowly lift the tungsten off the work piece to estalish  
the arc. (Note: Rocking the torch back onto the  
ceramic shielding cup is an easy way to do this  
steadily.)  
10. With the torch pointed in the direction of travel  
angled about 75 degrees to the work piece slowly  
move the torch in the direction of travel. Maintain  
about a 1/4” distance from the tungsten to the  
work piece while moving. Apply filler metal to the  
weld puddle by dipping the filler rod into the weld  
puddle allowing it to melt off and being careful not  
to touch the filler metal to the tungsten electrode.  
11. At the end of the weld lift the TIG torch quickly  
away from the work piece to break the arc.  
12. Turn off torch gas valve.  
13. Turn machine off.
