Use only correct fuses or circuit breakers. Do not oversize or by-
pass them.
D
D
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.
Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B
for hot work and have a fire watcher and extinguisher nearby.
D
Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watch-
person nearby. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the breath-
ing air is safe.
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
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
Wear approved safety glasses with side
shields even under your welding helmet.
Do not weld on coated metals, such as galvanized, lead, or
cadmiumplated steel, unless the coating is removed from the weld
area, the area is well ventilated, and while wearing an air-supplied

1-6. EMF Information
Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic Fields
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.
Welding current, as it flows through welding cables, will cause electro-
magnetic 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 power-
frequency 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.
4. Keep welding power source and cables as far away from opera-
tor as practical.
5. Connect work clamp to workpiece as close to the weld as possi-
ble.
About Implanted Medical Devices:
ImplantedMedical 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 recom-
mended.
To reduce magnetic fields in the workplace, use the following
procedures:

Considérationssur le soudage et les effets de basse fréquence et des
champs magnétiques et électriques.
1. Garder les câbles ensemble, les torsader, les scotcher, ou les
recouvrir d’une housse.
2. Disposer les câbles d’un côté et à distance de l’opérateur.
3. Ne pas courber pas et ne pas entourer pas les câbles autour de
votre corps.
4. Garder le poste de soudage et les câbles le plus loin possible de
vous.
Le courant de soudage, pendant son passage dans les câbles de sou-
dage, causera des champs électromagnétiques. Il y a eu et il y a encore
un certain souci à propos de tels champs. Cependant, après avoir exa-
miné 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
magnétiqueset 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
souhaitablede réduire votre exposition aux champs électromagnéti-
ques pendant le soudage ou le coupage.
5. Connecter la pince sur la pièce aussi près que possible de la
soudure.
En ce qui concerne les implants médicaux :
Les porteurs d’implants doivent d’abord consulter leur médecin avant
de s’approcher des opérations de soudage à l’arc, de soudage par
points, de gougeage, du coupage plasma ou de chauffage par induc-
tion. Si le médecin approuve, il est recommandé de suivre les
procédures précédentes.
Pour réduire les champs magnétiques sur le poste de travail, appliquer
les procédures suivantes :

Welding Status
Gun Selection
When either a MIG gun or spool gun trigger
is pressed and a welding arc is established,
the voltmeter displays actual weld voltage.
When the gun trigger is released and
welding arc extinguished, the voltmeter
displays the last actual voltage for 5
seconds and then returns to preset voltage.
If welding resumes before unit displays
preset voltage, actual welding voltage will
appear on the voltmeter.
Wire Feed Speed Meter
The wire feed speed meter will display
preset wire feed speed (IPM) for the
appropriate gun selection either MIG,
Spool or Push/Pull gun. To preset desired
wire feed speed, connect desired gun,
press gun trigger for one second, and
release trigger. The meter preset will be
retainedby the meter board until a different
gun is connected and preset is performed
or the unit is turned off and back on. The
settings for the last active gun used will be
the default at initial power up of the unit.
Power Up Status
Both meters display 888 at unit power up.
After 0.5 seconds, preset values appear on
both meters. The settings for the last active
gun used will be the default at initial power
up of the unit. If the power is reset to quickly,
characters other than 888 may appear. To
reset, turn power off for at least 3 seconds,
then turn power back on.
The wire feed speed meter always displays
preset wire feed speed (IPM).
5-3. Jog Mode
If the trigger on either gun is held for more than 3 seconds without striking an arc, the unit will automatically shut off
weld power (and shielding gas output on MIG or push/pull gun), but will feed wire continuously at the preset wire feed
speed (which may be faster or slower than Run−in Speed) until trigger is released. Jog wire feed speed is the same as
weld wire feed speed, so any time jog speed is changed, be sure to change back to weld wire feed speed before weld-
ing. Jog wire feed speed for the spool gun and push/pull gun is limited to 300 ipm (7.6 m/min).
