training before using this equipment. Some of these practices apply to equipment
connected to power lines; other practices apply to engine driven equipment. Anyone not having extensive
training in welding and cutting practices should not attempt to weld.
Safe practices are outlined in the American National Standard Z49.1 entitled: SAFETY IN WELDING AND CUTTING. This publication and other
guides to what you should learn before operating this equipment are listed at the end of these safety precautions. HAVE ALL INSTALLATION,
OPERATION, MAINTENANCE, AND REPAIR WORK PERFORMED ONLY BY QUALIFIED PEOPLE.
1.01 Arc Welding Hazards
WARNING
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.
1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body protection.
3. Insulate yourself from work and ground using dry insulating mats
or covers.
7. Use fully insulated electrode holders. Never dip holder in water to
cool it or lay it down on the ground or the work surface. Do not
touch holders connected to two welding machines at the same
r touch other people with the holder or electrode.

8. Do not use worn, damaged, undersized, or poorly spliced cables.
9. Do not wrap cables around your body.
10. Ground the workpiece to a good electrical (earth) ground.
11. Do not touch electrode while in contact with the work (ground)
circuit.
12. Use only well-maintained equipment. Repair or replace damaged
parts at once.
13. In confined spaces or damp locations, do not use a welder with
AC output unless it is equipped with a voltage reducer. Use
equipment with DC output.
14. Wear a safety harness to prevent falling if working above floor
level.
15. Keep all panels and covers securely in place.
WARNING
4. Disconnect input power or stop engine before installing or
servicing this equipment. Lock input power disconnect switch
open, or remove line fuses so power cannot be turned on
accidentally.
5. Properly install and ground this equipment according to its Owner’s
Manual and national, state, and local codes.
6. Turn off all equipment when not in use. Disconnect power to
equipment if it will be left unattended or out of service.
Manual No. 0-4838 1-1 SAFETY
ARC RAYS can burn eyes and skin; NOISE can damage
hearing. Arc rays from the welding process produce
intense heat and strong ultraviolet rays that can burn
eyes and skin. Noise from some processes can damage
hearing.
1. Wear a welding helmet fitted with a proper shade of filter (see
ANSI Z49.1 listed in Safety Standards) to protect your face and
eyes when welding or watching.
2. Wear approved safety glasses. Side shields recommended.

3. Use protective screens or barriers to protect others from flash
and glare; warn others not to watch the arc.
4. Wear protective clothing made from durable, flame-resistant
material (wool and leather) and foot protection.
5. Use approved ear plugs or ear muffs if noise level is high.
WARNING
WARNING
WELDING can cause fire or explosion.
Sparks and spatter fly off from the welding arc. The flying
sparks and hot metal, weld spatter, hot workpiece, and
hot equipment can cause fires and burns. Accidental
contact of electrode or welding wire to metal objects
can cause sparks, overheating, or fire.
FUMES AND GASES can be hazardous to your health.
Welding produces fumes and gases. Breathing these
fumes and gases can be hazardous to your health.
1. Keep your head out of the fumes. Do not breath the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to remove
welding fumes and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instruction for metals, consumables, coatings, and
cleaners.
5. Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Shielding gases used for
welding can displace air causing injury or death. Be sure the
breathing air is safe.
6. 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.
7. 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.

Considerations About Welding And The Effects of Low
Frequency Electric and Magnetic Fields
The following is a quotation from the General Conclusions Section of
the U.S. Congress, Office of Technology Assessment, Biological Effects
of Power
Frequency Electric & Magnetic Fields - Background Paper, OTA-BP-E63 (Washington, DC: U.S. Government Printing Office, May 1989):
“...there is now a very large volume of scientific findings based on
experiments at the cellular level and from studies with animals and
people which clearly establish that low frequency magnetic fields and
interact with, and produce changes in, biological systems. While most
of this work is of very high quality, the results are complex. Current
scientific understanding does not yet allow us to interpret the evidence
in a single coherent framework. Even more frustrating, it does not yet
allow us to draw definite conclusions about questions of possible risk
or to offer clear science-based advice on strategies to minimize or
avoid potential risks.”
To reduce magnetic fields in the workplace, use the following
procedures.
1. Keep cables close together by twisting or
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cable around the body.
4. Keep welding power source and cables as far away from
body as practical.

et aux produits nettoyants.
5. Ne travaillez dans un espace confiné que s’il est bien ventilé; sinon,
portez un respirateur à adduction d’air. Les gaz protecteurs de
soudage peuvent déplacer l’oxygène de l’air et ainsi causer des
malaises ou la mort. Assurez-vous que l’air est propre à la respiration.
6. Ne soudez pas à proximité d’opérations de dégraissage, de
nettoyage ou de pulvérisation. La chaleur et les rayons de l’arc
peuvent réagir avec des vapeurs et former des gaz hautement
toxiques et irritants.

2.09 Duty Cycle
Duty Cycle is the amount of arc-on time (actual welding
or cutting time) during any 10 minute period that a
machine can operate at it’s rated output without damaging
internal components. For example, the Fabricator 190 is
designed for 15% duty cycle at 190 amps. This means
that it has been designed and built to provide the rated
amperage, 190 amps, for 1 minute and 30 seconds out
of every 10 minute period. During the other 8 minutes 30
seconds of the 10 minute period the Fabricator 190 must
idle and be allowed to cool. The thermal cutout will operate
if the duty cycle is exceeded.
