FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
D Keep your head out of the fumes. Do not breathe the fumes.
D If inside, ventilate the area and/or use local forced ventilation at the
arc to remove welding fumes and gases.
D If ventilation is poor, wear an approved air-supplied respirator.
D Read and understand 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 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.
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 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.
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.
D After completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.
D Use only correct fuses or circuit breakers. Do not oversize or by-
pass them.
D 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.
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.
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.
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 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).
D Wear approved safety glasses with side shields under your
helmet.
D Use protective screens or barriers to protect others from flash,
glare and sparks; warn others not to watch the arc.
D Wear protective clothing made from durable, flame-resistant mate-
rial (leather, heavy cotton, or wool) and foot protection.
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
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 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 Do not weld where flying sparks can strike flammable material.
D Protect yourself and others from flying sparks and hot metal.
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 Do not weld where the atmosphere may contain flammable dust,
gas, or liquid vapors (such as gasoline).

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.

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
les procédures suivantes :

1 Voltage/Wire Speed Meter
2 Voltage/Wire Speed Switch
When switch is in Voltage position, and
operator is welding, meter displays arc
voltage. Cable resistance and poor
connections may cause displayed voltage to
vary slightly from actual voltage at welding
arc.
When switch is in Wire Speed position and
operator is welding, meter displays preset
wire speed in inches per minute. This wire
speed is the combined settings of the Weld
Speed Control on unit and Wire Speed Control
on gun.
During run-in portion of weld cycle, meter
displays run-in speed as selected on Run-In
Speed control on feeder.
When welding Direct Current Electrode
Negative (DCEN), meter does not display
accurate output voltages; however, meter
displays accurate wire speed values.
