WARNING
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause
fatal shocks or severe burns. The electrode
and work circuit is electrically live when-
ever the output is on. The input power cir-
cuit 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.

Manual 0-5242 1-3 GENERAL INFORMATION
WARNING
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 breathe
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 venti-
lated, 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 vapours 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 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 con-
tact of electrode or welding wire to metal
objects can cause sparks, overheating,
or fire.
1. Protect yourself and others from flying sparks and
hot metal.
2. Do not weld where flying sparks can strike flam-
mable material.
3. Remove all flammables within 10M of the welding
arc. If this is not possible, tightly cover them 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 for fire, and keep a fire extinguisher nearby.
6. Be aware that welding on a ceiling, floor, bulkhead,
or partition can cause fire on the hidden side.
7. Do not weld on closed containers such as tanks
or drums.
8. Connect work cable to the work as close to the
welding area as practical to prevent welding cur-
rent from travelling long, possibly unknown paths
and causing electric shock and fire hazards.
9. Do not use welder to thaw frozen pipes.
10.Remove stick electrode from holder or cut off
welding wire at contact tip when not in use.
WARNING
FLYING SPARKS AND HOT METAL can
cause injury.
Chipping and grinding cause flying metal.
As welds cool, they can throw off slag.
1. Wear approved face shield or safety goggles. Side
shields recommended.
2. Wear proper body protection to protect skin.
WARNING
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.
1. Protect compressed gas cylinders from excessive
heat, mechanical shocks, and arcs.
2. Install and secure cylinders in an upright position
by chaining them to a stationary support or equip-
ment cylinder rack to prevent falling or tipping.
3. Keep cylinders away from any welding or other
electrical circuits.
4. Never allow a welding electrode to touch any
cylinder.

TRANSTIG 170Pi
GENERAL INFORMATION 1-4 Manual 0-5242
5. Use only correct shielding gas cylinders,
regulators, hoses, and fittings designed for the
specific application; maintain them and associated
parts in good condition.
6. Turn face away from valve outlet when opening
cylinder valve.
7. Keep protective cap in place over valve except
when cylinder is in use or connected for use.
8. Read and follow instructions on compressed
gas cylinders, associated equipment, and CGA
publication P-1 listed in Safety Standards.
WARNING
MOVING PARTS can cause injury.
Moving parts, such as fans, rotors, and belts can cut
fingers and hands and catch loose clothing.
1. Keep all doors, panels, covers, and guards closed
and securely in place.
2. Stop engine before installing or connecting unit.
3. Have only qualified people remove guards or
covers for maintenance and troubleshooting as
necessary.
4. To prevent accidental starting during servicing,
disconnect negative (-) battery cable from battery.
5. Keep hands, hair, loose clothing, and tools away
from moving parts.
6. Reinstall panels or guards and close doors when
servicing is finished and before starting engine.
!
WARNING
This product, when used for welding or
cutting, produces fumes or gases which
contain chemicals know to the State of
California to cause birth defects and, in
some cases, cancer. (California Health &
Safety code Sec. 25249.5 et seq.)
NOTE
Considerations About Welding And The
Effects of Low Frequency Electric and
Magnetic Fields
The following is a quotation from the General Con-
clusions 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. Govern-
ment 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 coher-
ent 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 taping
them.
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.
ABOUT PACEMAKERS:
The above procedures are among those
also normally recommended for pace-
maker wearers. Consult your doctor for
complete information.

Manual 0-5242 1-9 GENERAL INFORMATION
1.05 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 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.
WARNING
