GENERAL INFORMATION 1-2 Manual 0-5196
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.
TRANSMIG 2RT
2. Do not weld where flying sparks can strike flammable
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.
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 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.
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 current 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
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.
1. Protect yourself and others from flying sparks and hot
metal.
Manual 0-5196 1-3 GENERAL INFORMATION
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 equipment
cylinder rack to prevent falling or tipping.
TRANSMIG 2RT
!
3. Keep cylinders away from any welding or other electrical circuits.
4. Never allow a welding electrode to touch any cylinder.
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.
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 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 taping them.
2. Arrange cables to one side and away from the operator.
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.)
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 pacemaker
wearers. Consult your doctor for complete
information.

SECTION 3: INSTALLATION OPERATION AND SETUP
3.01 Environment
These units are designed for use in environments with
increased hazard of electric shock as outlined in IEC
60974.5.
A. Examples of environments with increased hazard of
electric shock are:
1. In locations in which freedom of movement is restricted, so that the operator is forced to perform the
work in a cramped (kneeling, sitting or lying) position
with physical contact with conductive parts.
2. In locations which are fully or partially limited by conductive elements, and in which there is a high risk of
unavoidable or accidental contact by the operator.
3. In wet or damp hot locations where humidity or perspiration considerably reduces the skin resistance
of the human body and the insulation properties of
