This group of symbols means Warning! Watch Out! possible
ELECTRIC SHOCK, MOVING PARTS, and HOT PARTS hazards.
Consult symbols and related instructions below for necessary actions
to avoid the hazards.
1-2. Arc Welding Hazards
Y The symbols shown below are used throughout this manual to
call attention to and identify possible hazards. When you see
the symbol, watch out, and follow the related instructions to
avoid the hazard. The safety information given below is only
a summary of the more complete safety information found in
the Safety Standards listed in Section 1-4. Read and follow all
Safety Standards.
D If earth grounding of the workpiece is required, ground it directly
with a separate cable.
Y Only qualified persons should install, operate, maintain, and
repair this unit.
D Wear a safety harness if working above floor level.
D Keep all panels and covers securely in place.
Y During operation, keep everybody, especially children, away.
D Clamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The electrode and work circuit is
electrically live whenever the output is on. The input
power circuit and machine internal circuits are also
live when power is on. In semiautomatic or automatic wire welding, the
wire, wire reel, drive roll housing, and all metal parts touching the
welding wire are electrically live. Incorrectly installed or improperly
grounded equipment is a hazard.
D Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
D Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
D Insulate work clamp when not connected to workpiece to prevent
contact with any metal object.
D Do not connect more than one electrode or work cable to any
single weld output terminal.
SIGNIFICANT DC VOLTAGE exists after removal of
input power on inverters.
D Turn Off inverter, disconnect input power, and discharge input
capacitors according to instructions in Maintenance Section
before touching any parts.
D Do not touch live electrical parts.
D Wear dry, hole-free insulating gloves and body protection.
D Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the work
or ground.
D Do not use AC output in damp areas, if movement is confined, or if
there is a danger of falling.
D Use AC output ONLY if required for the welding process.
D If AC output is required, use remote output control if present on
unit.
D Disconnect input power or stop engine before installing or
servicing this equipment. Lockout/tagout input power according to
OSHA 29 CFR 1910.147 (see Safety Standards).
D Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.
D Keep your head out of the fumes. Do not breathe the fumes.
D Always verify the supply ground – check and be sure that input
power cord ground wire is properly connected to ground terminal in
disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
D When making input connections, attach proper grounding conductor first – double-check connections.
D Frequently inspect input power cord for damage or bare wiring –
replace cord immediately if damaged – bare wiring can kill.
D Turn off all equipment when not in use.
D Do not use worn, damaged, undersized, or poorly spliced cables.
D Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react with vapors to form
highly toxic and irritating gases.
D Do not drape cables over your body.
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
D If inside, ventilate the area and/or use exhaust at the arc to remove
welding fumes and gases.
D If ventilation is poor, use an approved air-supplied respirator.
D Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instructions for metals, consumables, coatings,
cleaners, and degreasers.
D Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watchperson nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the breathing air is safe.
D Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the weld
area, the area is well ventilated, and if necessary, while wearing an
air-supplied respirator. The coatings and any metals containing
these elements can give off toxic fumes if welded.
OM-2233 Page 1
ARC RAYS can burn eyes and skin.
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Sparks fly off from the
weld.
D Wear a welding helmet fitted with a proper shade of filter to protect
your face and eyes when welding or watching (see ANSI Z49.1
and Z87.1 listed in Safety Standards).
D Wear approved safety glasses with side shields under your
helmet.
D Use protective screens or barriers to protect others from flash and
glare; warn others not to watch the arc.
D Wear protective clothing made from durable, flame-resistant material (leather and wool) and foot protection.
BUILDUP OF GAS can injure or kill.
D Shut off shielding gas supply when not in use.
D Always ventilate confined spaces or use
approved air-supplied respirator.
HOT PARTS can cause severe burns.
D Do not touch hot parts bare handed.
D Allow cooling period before working on gun or
torch.
MAGNETIC FIELDS can affect pacemakers.
WELDING can cause fire or explosion.
Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up. Sparks
can fly off from the welding arc. The flying sparks, hot
workpiece, and hot equipment can cause fires and
burns. Accidental contact of electrode to metal objects can cause
sparks, explosion, overheating, or fire. Check and be sure the area is
safe before doing any welding.
D Protect yourself and others from flying sparks and hot metal.
D Do not weld where flying sparks can strike flammable material.
D Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
D Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
D Watch for fire, and keep a fire extinguisher nearby.
D Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
D Do not weld on closed containers such as tanks, drums, or pipes,
unless they are properly prepared according to AWS F4.1 (see
Safety Standards).
D Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
D Do not use welder to thaw frozen pipes.
D Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
D Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
D Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
FLYING METAL can injure eyes.
D Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
D Wear approved safety glasses with side
shields even under your welding helmet.
OM-2233 Page 2
D Pacemaker wearers keep away.
D Wearers should consult their doctor before
going near arc welding, gouging, or spot
welding operations.
NOISE can damage hearing.
Noise from some processes or equipment can
damage hearing.
D Wear approved ear protection if noise level is
high.
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode. Since
gas cylinders are normally part of the welding
process, be sure to treat them carefully.
D Protect compressed gas cylinders from excessive heat, mechanical shocks, slag, open flames, sparks, and arcs.
D Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
D Keep cylinders away from any welding or other electrical circuits.

1-5. EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic Fields
Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such
fields. However, after examining more than 500 studies spanning 17
years of research, a special blue ribbon committee of the National
Research Council concluded that: “The body of evidence, in the
committee’s judgment, has not demonstrated that exposure to powerfrequency electric and magnetic fields is a human-health hazard.”
However, studies are still going forth and evidence continues to be
examined. Until the final conclusions of the research are reached, you
may wish to minimize your exposure to electromagnetic fields when
welding or cutting.
To reduce magnetic fields in the workplace, use the following
procedures:
OM-2233 Page 4
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away from operator as practical.
5. Connect work clamp to workpiece as close to the weld as possible.
About Pacemakers:
Pacemaker wearers consult your doctor first. If cleared by your doctor,
then following the above procedures is recommended.

LES FUMÉES ET LES GAZ peuvent
être dangereux.
Le soudage génère des fumées et des gaz. Leur
inhalation peut être dangereux pour votre santé.
D
D
D
D
D
D
D Eloigner votre tête des fumées. Ne pas respirer
les fumées.
A l’intérieur, ventiler la zone et/ou utiliser un échappement au niveau
de l’arc pour l’évacuation des fumées et des gaz de soudage.
Si la ventilation est insuffisante, utiliser un respirateur à alimentation d’air homologué.
Lire les spécifications de sécurité des matériaux (MSDSs) et les
instructions du fabricant concernant les métaux, les consommables, les revêtements, les nettoyants et les dégraisseurs.
Travailler dans un espace fermé seulement s’il est bien ventilé ou en
portant un respirateur à alimentation d’air. Demander toujours à un
surveillant dûment formé de se tenir à proximité. Des fumées et des
gaz de soudage peuvent déplacer l’air et abaisser le niveau d’oxygène provoquant des blessures ou des accidents mortels. S’assurer que l’air de respiration ne présente aucun danger.
Ne pas souder dans des endroits situés à proximité d’opérations de
dégraissage, de nettoyage ou de pulvérisation. La chaleur et les
rayons de l’arc peuvent réagir en présence de vapeurs et former des
gaz hautement toxiques et irritants.
Ne pas souder des métaux munis d’un revêtement, tels que l’acier
galvanisé, plaqué en plomb ou au cadmium à moins que le revêtement n’ait été enlevé dans la zone de soudure, que l’endroit soit bien
ventilé, et si nécessaire, en portant un respirateur à alimentation
d’air. Les revêtements et tous les métaux renfermant ces éléments
peuvent dégager des fumées toxiques en cas de soudage.
OM-2233 Page 5
LES RAYONS DE L’ARC peuvent provoquer des brûlures dans les yeux et
sur la peau.
Le rayonnement de l’arc du procédé de soudage
génère des rayons visibles et invisibles intenses
(ultraviolets et infrarouges) susceptibles de provoquer
des brûlures dans les yeux et sur la peau. Des étincelles sont projetées
pendant le soudage.

et de l’éblouissement; demander aux autres personnes de ne pas regarder l’arc.
D Porter des vêtements de protection constitué dans une matière durable, résistant au feu (cuir ou laine) et une protection des pieds.
LE SOUDAGE peut provoquer un
incendie ou une explosion.
Le soudage effectué sur des conteneurs fermés tels
que des réservoirs, tambours ou des conduites peut
provoquer leur éclatement. Des étincelles peuvent être
projetées de l’arc de soudure. La projection d’étincelles, des pièces chaudes et des équipements chauds peut provoquer des
incendies et des brûlures. Le contact accidentel de l’électrode avec des
objets métalliques peut provoquer des étincelles, une explosion, un
surchauffement ou un incendie. Avant de commencer le soudage, vérifier
et s’assurer que l’endroit ne présente pas de danger.
D Se protéger et d’autres personnes de la projection d’étincelles et de
métal chaud.
D Ne pas souder dans un endroit là où des étincelles peuvent tomber sur
des substances inflammables.
D Déplacer toutes les substances inflammables à une distance de 10,7
m de l’arc de soudage. En cas d’impossibilité les recouvrir soigneusement avec des protections homologués.
D Des étincelles et des matériaux chauds du soudage peuvent facilement passer dans d’autres zones en traversant de petites fissures et
des ouvertures.
D Surveiller tout déclenchement d’incendie et tenir un extincteur à proximité.
D Le soudage effectué sur un plafond, plancher, paroi ou séparation
peut déclencher un incendie de l’autre côté.
D Ne pas effectuer le soudage sur des conteneurs fermés tels que des
réservoirs, tambours, ou conduites, à moins qu’ils n’aient été préparés correctement conformément à AWS F4.1 (voir les normes de
sécurité).

Afin de réduire les champs électromagnétiques dans l’environnement
de travail, respecter les consignes suivantes :
1
Le courant de soudage, pendant son passage dans les câbles de soudage, causera des champs électromagnétiques. Il y a eu et il y a encore
un certain souci à propos de tels champs. Cependant, après avoir examiné plus de 500 études qui ont été faites pendant une période de
recherche de 17 ans, un comité spécial ruban bleu du National Research Council a conclu: “L’accumulation de preuves, suivant le
jugement du comité, n’a pas démontré que l’exposition aux champs
magnétiques et champs électriques à haute fréquence représente un
risque à la santé humaine”. Toutefois, des études sont toujours en cours
et les preuves continuent à être examinées. En attendant que les conclusions finales de la recherche soient établies, il vous serait
souhaitable de réduire votre exposition aux champs électromagnétiques pendant le soudage ou le coupage.

1
TIG Electrode
2
Workpiece
Turn gas on. Touch tungsten electrode to workpiece at weld start
point. Hold electrode to workpiece for 1-2 seconds, and slowly
lift electrode. Arc is formed when
electrode is lifted.
Normal open-circuit voltage is not
present before tungsten electrode
touches workpiece; only a low
sensing voltage is present between
electrode and workpiece. The
solid-state output contactor does
not energize until after electrode is
touching workpiece. This allows
electrode to touch workpiece without overheating, sticking, or getting
contaminated.
Application:
Lift-Arc is used for the DCEN
GTAW process when HF Start
method is not permitted, or to replace the scratch method.
Do NOT Strike Like A Match!

Y Grinding the tungsten electrode produces dust and flying sparks which can cause
injury and start fires. Use local exhaust (forced ventilation) at the grinder or wear an
approved respirator. Read
MSDS for safety information.
Consider using tungsten
containing ceria, lanthana,
or yttria instead of thoria.
Grinding dust from thoriated
electrodes contains low-level radioactive material.
Properly dispose of grinder
dust in an environmentally
safe way. Wear proper face,
hand, and body protection.
Keep flammables away.

Y Grinding the tungsten electrode produces dust and flying sparks which can cause
injury and start fires. Use local exhaust (forced ventilation) at the grinder or wear an
approved respirator. Read
MSDS for safety information.
Consider using cerium or
lanthanum based tungsten
instead of thoriated. Thorium dust contains low-level
radioactive material. Properly dispose of grinder dust in
an environmentally safe way.
Wear proper face, hand, and
body protection. Keep flammables away.

Bottom View Of Gas Cup
The inside diameter of the gas cup
should be at least three times the
tungsten diameter to provide adequate shielding gas coverage. (For
example, if tungsten is 1/16 in
diameter, gas cup should be a
minimum of 3/16 in diameter.
Tungsten extension is the distance
the tungsten extends out gas cup of
torch.
The tungsten extension should be
no greater than the inside diameter
of the gas cup.
Arc length is the distance from the
tungsten to the workpiece.

Miller’s True Blue Limited Warranty shall not apply to:
1.
Consumable components; such as contact tips,
cutting nozzles, contactors, brushes, slip rings,
relays or parts that fail due to normal wear.
2.
Items furnished by Miller, but manufactured by others,
such as engines or trade accessories. These items are
covered by the manufacturer’s warranty, if any.
3.
Equipment that has been modified by any party other
than Miller, or equipment that has been improperly
installed, improperly operated or misused based upon
industry standards, or equipment which has not had
reasonable and necessary maintenance, or equipment
which has been used for operation outside of the
specifications for the equipment.
MILLER PRODUCTS ARE INTENDED FOR PURCHASE
AND USE BY COMMERCIAL/INDUSTRIAL USERS AND
PERSONS TRAINED AND EXPERIENCED IN THE USE
AND MAINTENANCE OF WELDING EQUIPMENT.
In the event of a warranty claim covered by this warranty, the
exclusive remedies shall be, at Miller’s option: (1) repair; or (2)
replacement; or, where authorized in writing by Miller in
appropriate cases, (3) the reasonable cost of repair or
replacement at an authorized Miller service station; or (4)
payment of or credit for the purchase price (less reasonable
depreciation based upon actual use) upon return of the goods
at customer’s risk and expense. Miller’s option of repair or
replacement will be F.O.B., Factory at Appleton, Wisconsin, or
F.O.B. at a Miller authorized service facility as determined by
Miller. Therefore no compensation or reimbursement for
transportation costs of any kind will be allowed.
TO THE EXTENT PERMITTED BY LAW, THE REMEDIES
PROVIDED HEREIN ARE THE SOLE AND EXCLUSIVE
REMEDIES. IN NO EVENT SHALL MILLER BE LIABLE FOR
DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF
PROFIT), WHETHER BASED ON CONTRACT, TORT OR
ANY OTHER LEGAL THEORY.
ANY EXPRESS WARRANTY NOT PROVIDED HEREIN
AND ANY IMPLIED WARRANTY, GUARANTY OR
REPRESENTATION AS TO PERFORMANCE, AND ANY
REMEDY FOR BREACH OF CONTRACT TORT OR ANY
OTHER LEGAL THEORY WHICH, BUT FOR THIS
PROVISION,
MIGHT
ARISE
BY
IMPLICATION,
OPERATION OF LAW, CUSTOM OF TRADE OR COURSE
OF DEALING, INCLUDING ANY IMPLIED WARRANTY OF
MERCHANTABILITY OR FITNESS FOR PARTICULAR
PURPOSE, WITH RESPECT TO ANY AND ALL
EQUIPMENT FURNISHED BY MILLER IS EXCLUDED AND
DISCLAIMED BY MILLER.
Some states in the U.S.A. do not allow limitations of how long
an implied warranty lasts, or the exclusion of incidental,
indirect, special or consequential damages, so the above
limitation or exclusion may not apply to you. This warranty
provides specific legal rights, and other rights may be
available, but may vary from state to state.
In Canada, legislation in some provinces provides for certain
additional warranties or remedies other than as stated herein,
and to the extent that they may not be waived, the limitations
and exclusions set out above may not apply. This Limited
Warranty provides specific legal rights, and other rights may
be available, but may vary from province to province.
