4. Be alert that welding sparks and hot materials from
welding can easily go through small cracks and open­ings to adjacent areas.

WARNING

FUMES AND GASES can be hazardous to
your health.

Welding produces fumes and gases. Breath

­ing 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 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.

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 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.

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. 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 equipment
cylinder rack to prevent falling or tipping.

3. Keep cylinders away from any welding or other electri­cal circuits.

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 10M of the welding
arc. If this is not possible, tightly cover them with
approved covers.

Manual 0-5231 1-3 GENERAL INFORMATION

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.

TRANSMIG VAF4

!

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.

NOTE

Considerations About Welding And The
Effects of Low Frequency Electric and Mag

-

netic 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 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.

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.)

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 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
accessories.

B. Environments with increased hazard of electric
shock do not include places where electrically conduc­tive parts in the near vicinity of the operator, which can
cause increased hazard, have been insulated.

3.02 Location

Be sure to locate the wirefeeder according to the fol­lowing guidelines:

A. In areas, free from moisture and dust.

B. Ambient temperature between 0° C to 40° C.

C. In areas, free from oil, steam and corrosive gases.

D. In areas, not subjected to abnormal vibration or

shock.

E. In areas, not exposed to direct sunlight or rain.

F. The enclosure design of this Wire Feeder meets the

requirements of IP23S as outlined in AS 60529. This
provides adequate protection against solid objects
(greater than 12mm), and direct protection from
vertical drops. Under no circumstances should the
unit be operated or connected in a micro environ­ment that will exceed the stated conditions. For
further information please refer to AS 60529.

G. Precautions must be taken against the Wire Feeder

toppling over. The Wire Feeder must be located on
a suitable horizontal surface in the upright position
when in use.

3.03 Ventilation

WARNING

Since the inhalation of welding fumes can
be harmful, ensure that the welding area is
effectively ventilated.

3.04 Mains Supply Voltage Requirements

CAUTION

This wirefeeder cannot be connected directly
to the mains supply. It must be connected
to a suitable wirefeeder control socket on a
power source.

3.05 Electromagnetic Compatibility

WARNING

Extra precautions for Electromagnetic
Compatibility may be required when this
Welding Power Source is used in a domestic
situation.

A. Installation and Use - Users Responsibility

The user is responsible for installing and using the
welding equipment according to the manufacturer’s
instructions. If electromagnetic disturbances are
detected then it shall be the responsibility of the user
of the welding equipment to resolve the situation with
the technical assistance of the manufacturer. In some
cases this remedial action may be as simple as earthing
the welding circuit, see NOTE below. In other cases it
could involve constructing an electromagnetic screen
enclosing the Welding Power Source and the work,
complete with associated input filters. In all cases,
electromagnetic disturbances shall be reduced to the
point where they are no longer Trouble-some.

NOTE

The welding circuit may or may not be
earthed for safety reasons. Changing the
earthing arrangements should only be au­thorised by a person who is competent to
assess whether the changes will increase the
risk of injury, e.g. by allowing parallel weld­ing current return paths which may damage
the earth circuits of other equipment. Further
guidance is given in IEC 60974-13 Arc Weld­ing Equipment - Installation and use (under
preparation).

Manual 0-5231 3-1 INSTALLATION, OPERATION AND SETUP

TRANSMIG VAF4

B. Assessment of Area

3. Welding Cables

Before installing welding equipment, the user shall make
an assessment of potential electromagnetic problems
in the surrounding area. The following shall be taken
into account.

1. Other supply cables, control cables, signalling and
telephone cables; above, below and adjacent to the
welding equipment.

2. Radio and television transmitters and receivers.

3. Computer and other control equipment.

4. Safety critical equipment, e.g. guarding of industrial
equipment.

5. The health of people around, e.g. the use of pace­makers and hearing aids.

6. Equipment used for calibration and measurement.

7. The time of day that welding or other activities are
to be carried out.

8. The immunity of other equipment in the environment:
the user shall ensure that other equipment being
used in the environment is compatible: this may
require additional protection measures.

The size of the surrounding area to be considered
will depend on the structure of the building and other
activities that are taking place. The surrounding area
may extend beyond the boundaries of the premises.

C. Methods of Reducing Electromagnetic Emissions

The welding cables should be kept as short as

possible and should be positioned close together
but never coiled and running at or close to the floor
level.

4. Equipotential Bonding

Bonding of all metallic components in the welding

installation and adjacent to it should be considered.
However, metallic components bonded to the work
piece will increase the risk that the operator could
receive a shock by touching the metallic components
and the electrode at the same time. The operator
should be insulated from all such bonded metallic
components.

5. Earthing/grounding of the Work Piece

Where the work piece is not bonded to earth for

electrical safety, nor connected to earth because
of its size and position, e.g. ship’s hull or building
steelwork, a connection bonding the work piece to
earth may reduce emissions in some, but not all
instances. Care should be taken to prevent the earth­ing of the work piece increasing the risk of injury
to users, or damage to other electrical equipment.
Where necessary, the connection of the work piece
to earth should be made by direct connection to
the work piece, but in some countries where direct
connection is not permitted, the bonding should be
achieved by suitable capacitance, selected according
to national regulations.

1. Mains Supply

Welding equipment should be connected to the

mains supply according to the manufacturer’s
recommendations. If interference occurs, it may
be necessary to take additional precautions such
as filtering of the mains supply. Consideration
should be given to shielding the supply cable
of permanently installed welding equipment in
metallic conduit or equivalent. Shielding should be
electrically continuous throughout its length. The
shielding should be connected to the Welding Power
Source so that good electrical contact is maintained
between the conduit and the Welding Power Source
enclosure.

2. Maintenance of Welding Equipment

The welding equipment should be routinely

maintained according to the manufacturer’s
recommendations. All access and service doors and
covers should be closed and properly fastened when
the welding equipment is in operation. The welding
equipment should not be modified in any way except
for those changes and adjustments covered in the
manufacturer’s instructions.

6. Screening and Shielding

Selective screening and shielding of other cables

and equipment in the surrounding area may alleviate
problems of interference. Screening the entire
welding installation may be considered for special
applications.
