FOR ENGINE
powered equipment.
1.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.
1.a. Turn the engine off before troubleshooting and maintenance
work unless the maintenance work requires it to be running.
____________________________________________________
1.b. Operate engines in open, well-ventilated
areas or vent the engine exhaust fumes
outdoors.
____________________________________________________
1.c. Do not add the fuel near an open flame
welding arc or when the engine is running.
Stop the engine and allow it to cool before
refueling to prevent spilled fuel from vaporizing on contact with hot engine parts and
igniting. Do not spill fuel when filling tank. If
fuel is spilled, wipe it up and do not start
engine until fumes have been eliminated.
____________________________________________________
1.d. Keep all equipment safety guards, covers and devices in
position and in good repair.Keep hands, hair, clothing and
tools away from V-belts, gears, fans and all other moving
parts when starting, operating or repairing equipment.
____________________________________________________
1.e. In some cases it may be necessary to remove safety
guards to perform required maintenance. Remove
guards only when necessary and replace them when the
maintenance requiring their removal is complete.

___________________________________________________
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.
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.
2.d.4. Connect the work cable to the workpiece as close as
possible to the area being welded.
___________________________________________________
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.5. Do not work next to welding power source.

SAFETY
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.
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 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 products.
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.
5.f. Also see item 1.b.

SAFETY
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
the welding sparks from starting a fire.
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 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).
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.
6.g. Connect the work cable to the work as close to the welding
area as practical. Work cables connected to the building
framework or other locations away from the welding area
increase the possibility of the welding current passing
through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains
or cables until they fail.
6.h. Also see item 1.c.
CYLINDER may explode
if damaged.
7.a. Use only compressed gas cylinders
containing the correct shielding gas for the
process used and properly operating
regulators designed for the gas and
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.
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.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
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.
FOR ELECTRICALLY
powered equipment.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
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
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.
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.
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
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.

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 competent 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 problems 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 recommendations. 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 equipment, 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 equipment 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 connection 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 problems of interference. Screening of the entire welding installation may be considered for special applications.

STACKING
The INVERTER ARC™ 230 cannot be stacked.
Check the input voltage, phase, and frequency supplied to this machine before turning it on. The allowable input voltage is indicated in the technical specification section of this manual and on the rating plate of
the machine. Be sure that the machine is grounded.
Make sure the power available at the input connection
is adequate for normal operation of the machine. The
fuse rating and cable sizes are both indicated in the
technical specification section of this manual.
Fuse the input circuit with time delay fuses marked “D”
or delay type(1) circuit breakers. Using fuses or circuit
breakers smaller than recommended may result in
“nuisance” shut-offs from welder inrush currents even
if not welding at high currents.
(1)
Also called “inverse time” or “thermal/magnetic” circuit breakers.
These circuit breakers have a delay in tripping action that
decreases as the magnitude of the current increases.
The INVERTER ARC™ 230 is recommended for use
on an individual branch circuit.

OPERATION
STICK-WELDING CIRCUIT
B-3
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.
(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 garden 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 electrode 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.
To weld, the work clamp must be tightly connected to
clean base metal. Remove paint, rust, etc. as necessary 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 1/161/8” 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.
ELECTRIC ARC (Stick-Welding)
(See Figure B.4)
Action that takes place in the electric arc.
FIGURE B.4
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 covering also melts or burns in the arc. It has several functions. 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.
MAKING A WELD
Insert the bare part of the electrode into the electrode
holder jaws and connect the work clamp to the welding 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 workpiece as if striking a match. Do not hit the electrode
on the workpiece, which will damage the stick electrode 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.
NOTE: If you stop moving the electrode while scratching, 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.
INVERTER ARC™ 230

OPERATION
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 righthanded). Hold the electrode at a slight angle as
shown. (See Figure B.5)
FIGURE B.5
5. As the electrode burns off the electrode must be fed
to the work to maintain correct arc length. The easiest 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)
FIGURE B.6
8. Turn the machine off and remove the stub by opening 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 setting down the Electrode Holder.
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 electrode 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 tungsten 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.
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 addition, 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.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.
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 terminal.
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:
Steel Thickness
(1/16”) 1.6mm
(1/8”) 3.2mm
(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.
