and glare; warn others not to watch the arc.
4. Wearprotective clothing made from durable, flame-resistant
material (wool and leather) and foot protection.
5. Use approved earplugs orearmuffs if noise level is high.
WARNING
FUMES AND GASES can be hazardous to yourhealth.
Welding produces fumes and gases. Breathing these
fumes and gases can be hazardous to yourhealth.
1. Keep yourhead out of the fumes. Do not breath the fumes.
2. If inside, ventilate the area and/oruse 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 formetals, consumables, coatings, and
cleaners.
5. Work in a confined space only if it is well ventilated, orwhile
wearing an air-supplied respirator. Shielding gases used for
welding can displace aircausing injury ordeath. Be sure the
breathing airis safe.
6. Do not weld in locations neardegreasing, cleaning, orspraying
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.
WARNING
WELDING can cause fire orexplosion.
Sparks and spatterfly 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 orwelding wire to metal objects
can cause sparks, overheating, orfire.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material.
3. Remove all flammables within 35 ft (10.7 m) of the welding arc.
If this is not possible, tightly coverthem with approved covers.
4. Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
5. Watch forfire, and keep a fire extinguishernearby.
6. Be aware that welding on a ceiling, floor, bulkhead, orpartition
can cause fire on the hidden side.
7. Do not weld on closed containers such as tanks ordrums.
8. 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.
9. Do not use welderto thaw frozen pipes.
10. Remove stick electrode from holderorcut off welding wire at
contact tip when not in use.

NOTE
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-E-
63 (Washington, DC: U.S. Government Printing Office, May 1989):
“...there is now a very large volume of scientific findings based on
experiments at the cellularlevel 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
orto offerclearscience-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 togetherby twisting ortaping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil ordrape cable around the body.
4. Keep welding powersource and cables as faraway from
body as practical.
ABOUT PACEMAKERS:
The above procedures are among those also normally
recommended forpacemakerwearers. Consult your
doctorforcomplete information.

gun, work lead, and flow regulator. The following
instructions detail how to correctly set up the welderand
give guidelines on gaining the best production efficiency
from the PowerSupply. Please read these instructions
thoroughly before using yourFabricatorwelder.
2.05 Safety
The following basic safety rules should always be followed:
Ensure the machine is correctly installed, if necessary,
by a qualified electrician.
Ensure the PowerSupply is grounded correctly
(electrically) in accordance with local regulations.
Excessive heat in the welding cables may cause fire. Never
weld with poorelectrical connections, damaged welding
cables orexceed the welding cable current rating as this
will produce excessive heat and may cause a fire.
Always wearthe correct protective clothing forprotection
from sparks, molten particles and arc rays.
When welding in confined spaces, always ensure adequate
ventilation and constant observation of the operator.
Keep combustible materials away from the welding area.
Have a suitable fire extinguisherhandy.
Neverwatch the welding arc with naked eyes. Always use
and weara welding mask fitted with the correct filterlens.
Do not stand on damp ground when welding.
Formore complete safety advice, please read Section 1.
2.06 Protective Filter Lenses
Protective filterlenses are provided to reduce the intensity
of radiation entering the eye thus filtering out harmful
infrared, ultraviolet radiation and a percentage of the
visible light. Such filterlenses are incorporated within face
shields. To prevent damage to the filterlenses from molten
orhard particles an additional hard clearglass orspecial
plastic external coverlens should be used. This cover
lens should always be kept in place and replaced before
the damage impairs yourvision while welding.

2.09 Duty Cycle
Duty Cycle is the amount of arc-on time (actual welding
orcutting time) during any 10 minute period that a
machine can operate at it’s rated output without damaging
internal components. Forexample, the Fabricator190 is
designed for15% duty cycle at 190 amps. This means
that it has been designed and built to provide the rated
amperage, 190 amps, for1 minute and 30 seconds out
of every 10 minute period. During the other8 minutes 30
seconds of the 10 minute period the Fabricator190 must
idle and be allowed to cool. The thermal cutout will operate
if the duty cycle is exceeded.
