1-2.Arc Welding Hazards
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 1-5. Read and
follow all Safety Standards.
Only qualified persons should install, operate, maintain, and
repair this unit.
During operation, keep everybody, especially children, away.
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
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.
Do not touch live electrical parts.
Wear dry, hole-free insulating gloves and body protection.
Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the work
or ground.
Do not use AC output in damp areas, if movement is confined, or if
there is a danger of falling.
Use AC output ONLY if required for the welding process.
If AC output is required, use remote output control if present on
unit.
Additional safety precautions are required when any of the follow-
ing electrically hazardous conditions are present: 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; or when there is a high risk of unavoidable or accidental contact with the workpiece or ground. For these
conditions, use the following equipment in order presented: 1) a
semiautomatic DC constant voltage (wire) welder, 2) a DC manual
(stick) welder, or 3) an AC welder with reduced open-circuit voltage. In most situations, use of a DC, constant voltage wire welder
is recommended. And, do not work alone!

This group of symbols means Warning! Watch Out! ELECTRIC
SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult symbols and related instructions below for necessary actions to avoid the
hazards.
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.
When making input connections, attach proper grounding conduc-
tor first − double-check connections.
Keep cords dry, free of oil and grease, and protected from hot metal
and sparks.
Frequently inspect input power cord for damage or bare wiring −
replace cord immediately if damaged − bare wiring can kill.
Turn off all equipment when not in use.
Do not use worn, damaged, undersized, or poorly spliced cables.
Do not drape cables over your body.
If earth grounding of the workpiece is required, ground it directly
with a separate cable.
Do not touch electrode if you are in contact with the work, ground,
or another electrode from a different machine.
Do not touch electrode holders connected to two welding ma-
chines at the same time since double open-circuit voltage will be
present.
Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
Wear a safety harness if working above floor level.
Keep all panels and covers securely in place.
Clamp work cable with good metal-to-metal contact to workpiece
or worktable as near the weld as practical.
Insulate work clamp when not connected to workpiece to prevent
contact with any metal object.
Do not connect more than one electrode or work cable to any
single weld output terminal.

FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
Keep your head out of the fumes. Do not breathe the fumes.
If inside, ventilate the area and/or use local forced ventilation at the
arc to remove welding fumes and gases.
If ventilation is poor, wear an approved air-supplied respirator.
Read and understand the Material Safety Data Sheets (MSDSs)
and the manufacturer’s instructions for metals, consumables,
coatings, cleaners, and degreasers.
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.
Do not weld in locations near degreasing, cleaning, or spraying op-
erations. The heat and rays of the arc can react with vapors to form
highly toxic and irritating gases.
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 while wearing an air-supplied
respirator. The coatings and any metals containing these elements
can give off toxic fumes if welded.
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.
Wear an approved welding helmet fitted with a proper shade of fil-
ter lenses to protect your face and eyes when welding or watching
(see ANSI Z49.1 and Z87.1 listed in Safety Standards).
Wear approved safety glasses with side shields under your
helmet.
Use protective screens or barriers to protect others from flash,
glare and sparks; warn others not to watch the arc.
Wear protective clothing made from durable, flame-resistant mate-
rial (leather, heavy cotton, or wool) and foot protection.
WELDING can cause fire or explosion.
Do not use welder to thaw frozen pipes.
Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
After completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.
Use only correct fuses or circuit breakers. Do not oversize or by-
pass them.
Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B
for hot work and have a fire watcher and extinguisher nearby.
FLYING METAL or DIRT can injure eyes.
Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
Wear approved safety glasses with side
shields even under your welding helmet.
BUILDUP OF GAS can injure or kill.
Shut off shielding gas supply when not in use.
Always ventilate confined spaces or use
approved air-supplied respirator.
MAGNETIC FIELDS can affect Implanted
Medical Devices.
Wearers of Pacemakers and other Implanted
Medical Devices should keep away.
Implanted Medical Device wearers should consult their doctor
and the device manufacturer before going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating
operations.
NOISE can damage hearing.
Noise from some processes or equipment can
damage hearing.
Wear approved ear protection if noise level is
high.
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
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.
Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
Do not weld where flying sparks can strike flammable material.
Protect yourself and others from flying sparks and hot metal.
Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
Watch for fire, and keep a fire extinguisher nearby.
Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
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).
Do not weld where the atmosphere may contain flammable dust,
gas, or liquid vapors (such as gasoline).
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, sparks, and fire
hazards.
OM-222 Page 2
workpiece, and hot equipment can cause fires and
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.
Protect compressed gas cylinders from excessive heat, mechani-
cal shocks, physical damage, slag, open flames, sparks, and arcs.
Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
Keep cylinders away from any welding or other electrical circuits.
Never drape a welding torch over a gas cylinder.
Never allow a welding electrode to touch any cylinder.
Never weld on a pressurized cylinder − explosion will result.

1-6.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:
1. Keep cables close together by twisting or taping them, or using a
cable cover.
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 Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and the
device manufacturer before performing or going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating operations.
If cleared by your doctor, then following the above procedures is recommended.

LE SOUDAGE peut provoquer un in
cendie ou une explosion.
Le soudage effectué sur des conteneurs fermés tel
que des réservoirs, tambours ou des conduites pe
provoquer leur éclatement. Des étincelles peuve
être projetées de l’arc de soudure. La projection d’étincelles, des pièce
chaudes et des équipements chauds peut provoquer des incendies
des brûlures. Le contact accidentel de l’électrode avec des objet
métalliques peut provoquer des étincelles, une explosion, un surchau
fement ou un incendie. Avant de commencer le soudage, vérifier
s’assurer que l’endroit ne présente pas de danger.
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.
Ne pas souder dans un endroit là où des étincelles peuvent tomber
sur des substances inflammables.
Se protéger et d’autres personnes de la projection d’étincelles et
de métal chaud.
Des étincelles et des matériaux chauds du soudage peuvent
facilement passer dans d’autres zones en traversant de petites
fissures et des ouvertures.
Surveiller tout déclenchement d’incendie et tenir un extincteur à
proximité.
Le soudage effectué sur un plafond, plancher, paroi ou séparation
peut déclencher un incendie de l’autre côté.
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).
Ne soudez pas si l’air ambiant est chargé de particules, gaz, ou va-
peurs inflammables (vapeur d’essence, par exemple).
Brancher le câble de masse sur la pièce le plus près possible de la
zone de soudage pour éviter le transport du courant sur une
longue distance par des chemins inconnus éventuels en provoquant des risques d’électrocution, d’étincelles et d’incendie.
Ne pas utiliser le poste de soudage pour dégeler des conduites ge-
lées.
En cas de non utilisation, enlever la baguette d’électrode du porte-
électrode ou couper le fil à la pointe de contact.
Porter des vêtements de protection dépourvus d’huile tels que des
gants en cuir, une chemise en matériau lourd, des pantalons sans
revers, des chaussures hautes et un couvre chef.
Avant de souder, retirer toute substance combustible de vos po-
ches telles qu’un allumeur au butane ou des allumettes.
Une fois le travail achevé, assurez−vous qu’il ne reste aucune
trace d’étincelles incandescentes ni de flammes.
Utiliser exclusivement des fusibles ou coupe−circuits appropriés.
Ne pas augmenter leur puissance; ne pas les ponter.
Une fois le travail achevé, assurez−vous qu’il ne reste aucune

2-6.Information EMF
Considérations sur le soudage et les effets de basse fréquence et des
champs magnétiques et électriques.
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.
Pour réduire les champs magnétiques sur le poste de travail, appliquer
