1.2 Safety precautions
WARNING!
These Safety Precautions are for your protection. They summarise precautionary
information from the references listed in Additional Safety Information section. Before
performing any installation or operating procedures, be sure to read and follow the
safety precautions listed below as well as all other manuals, material safety data
sheets, labels, etc. Failure to observe Safety Precautions can result in injury or death.
PROTECT YOURSELF AND OTHERS
Some welding, cutting and gouging processes are noisy and require
ear protection. The arc, like the sun, emits ultraviolet (UV) and other
radiation and can injure skin and eyes. Hot metal can cause burns.
Training in the proper use of the processes and equipment is essential
to prevent accidents. Therefore:
1. Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes
when welding or watching.
2. Always wear safety glasses with side shields in any work area, even if welding
helmets face shields and goggles are also required.
3. Use a face shield fitted with the correct filter and cover plates to protect your eyes,
face, neck and ears from sparks and rays of the arc when operating or observing
operations. Warn bystanders not to watch the arc and not to expose themselves to the
rays of the electric-arc or hot metal.
4. Wear flameproof gauntlet type gloves, heavy long-sleeve shirt, cuff less trousers,
high-topped shoes and a welding helmet or cap for protection, to protect against arc
rays and hot sparks or hot metal. A flameproof apron may also be desirable as
protection against radiated heat and sparks.

5. Hot sparks or metal can lodge in rolled up sleeves, trouser cuffs, or pockets. Sleeves
and collars should be kept buttoned and open pockets eliminated from the front of
clothing.
6. Protect other personnel from arc rays and hot sparks with a suitable non-flammable
partition or curtains.
7. Use goggles over safety glasses when chipping slag or grinding. Chipped slag may be
hot and can fly far. Bystanders should also wear goggles over safety glasses.
FIRES AND EXPLOSIONS
Heat from flames and arcs can start fires. Hot slag or sparks can also
cause fires and explosions. Therefore:
1. Protect yourself and others from flying sparks and hot metal.
2. Remove all combustible materials well away from the work area or cover the materials
with a protective non-flammable covering. Combustible materials include wood, cloth,
sawdust, liquid and gas fuels, solvents, paints and coatings paper, etc.
3. Hot sparks or hot metal can fall through cracks or crevices in floors or wall openings
and cause a hidden smoldering fire or fires on the floor below. Make certain that such
openings are protected from hot sparks and metal.
4. Do not weld, cut or perform other hot work until the work piece has been completely
cleaned so that there are no substances on the work piece which might produce
flammable or toxic vapors. Do not do hot work on closed containers, they may
explode.
5. Have fire extinguishing equipment handy for instant use, such as a garden hose,
water pail, sand bucket, or portable fire extinguisher. Be sure you are trained in its
use.
6. Do not use equipment beyond its ratings. For example, an overloaded welding cable
can overheat and create a fire hazard.
7. After completing operations, inspect the work area to make certain there are no hot
sparks or hot metal which could cause a later fire. Use fire watchers when necessary.
ELECTRICAL SHOCK
Contact with live electrical parts and ground can cause severe injury
or death. DO NOT use AC welding current in damp areas, if movement
is confined, or if there is danger of falling. Therefore:
1. Be sure the power source frame (chassis) is connected to the ground system of the
input power.
2. Connect the workpiece to a good electrical ground.
3. Connect the work cable to the workpiece. A poor or missing connection can expose
you or others to a fatal shock.
4. Use well-maintained equipment. Replace worn or damaged cables.
5. Keep everything dry, including clothing, work area, cables, torch/electrode holder and
power source.
6. Make sure that all parts of your body are insulated from both the work piece and from
the ground.
7. Do not stand directly on metal or the earth while working in tight quarters or a damp
area; stand on dry boards or an insulating platform and wear rubber-soled shoes.
8. Put on dry, hole-free gloves before turning on the power.
9. Turn off the power before removing your gloves.
10. Refer to ANSI/ASC Standard Z49.1 for specific grounding recommendations. Do not
mistake the work lead for a ground cable.

ELECTRIC AND MAGNETIC FIELDS
May be dangerous. Electric current flowing through any conductor
causes localized Electric and Magnetic Fields (EMF). Welding and
cutting current creates EMF around welding cables and welding
machines. Therefore:
1. Welders having pacemakers should consult their physician before welding. EMF may
interfere with some pacemakers.
2. Exposure to EMF may have other health effects which are unknown.
3. Welders should use the following procedures to minimise exposure to EMF:
a) Route the electrode and work cables together. Secure them with tape when
possible.
b) Never coil the torch or work cable around your body.
c) Do not place your body between the torch and work cables. Route cables on
the same side of your body.
d) Connect the work cable to the workpiece as close as possible to the area being
welded.
e) Keep welding power source and cables as far away from your body as
possible.
FUMES AND GASES
Fumes and gases, can cause discomfort or harm, particularly in
confined spaces. Shielding gases can cause asphyxiation. Therfore:
1. Keep your head out of the fumes. Do not breathe the fumes and gases.
2. Always provide adequate ventilation in the work area by natural or mechanical means.
Do not weld, cut or gouge on materials such as galvanized steel, stainless steel,
copper, zinc, lead beryllium or cadmium unless positive mechanical ventilation is
provided. Do not breathe fumes from these materials.
3. Do not operate near degreasing and spraying operations. The heat or arc can react
with chlorinated hydrocarbon vapors to form phosgene, a highly toxic gas and other
irritant gases.
4. If you develop momentary eye, nose or throat irritation while operating, this is an
indication that ventilation is not adequate. Stop work and take necessary steps to
improve ventilation in the work area. Do not continue to operate if physical discomfort
persists.
5. Refer to ANSI/ASC Standard Z49.1 for specific ventilation recommendations.
6. WARNING: This product when used for welding or cutting, produces fumes or gases
which contain chemicals known to the State of California to cause birth defects and in
some cases cancer (California Health & Safety Code §25249.5 et seq.)
CYLINDER HANDLING
Cylinders, if mishandled, can rupture and violently release gas. A
sudden rupture of cylinder valve or relief device can injure or kill.
Therefore:
1. Locate cylinders away from heat, sparks and flames. Never strike an arc on a cylinder.
2. Use the proper gas for the process and use the proper pressure reducing regulator
designed to operate from the compressed gas cylinder. Do not use adaptors. Maintain
hoses and fittings in good condition. Follow manufacturer's operating instructions for
mounting regulator to a compressed gas cylinder.

3. Always secure cylinders in an upright position by chain or strap to suitable hand
trucks, undercarriages, benches, wall, post or racks. Never secure cylinders to work
tables or fixtures where they may become part of an electrical circuit.
4. When not in use, keep cylinder valves closed. Have valve protection cap in place if
regulator is not connected. Secure and move cylinders by using suitable hand trucks.
MOVING PARTS
Moving parts, such as fans, rotors and belts can cause
injury. Therefore:
1. Keep all doors, panels, guards and covers closed and securely in place.
2. Stop engine or drive systems before installing or connecting unit.
3. Have only qualified people remove covers for maintenance and troubleshooting as
necessary
4. To prevent accidental starting of equipment during service, disconnect negative (-)
battery cable from battery.
5. Keep hands, hair, loose clothing and tools away from moving parts.
6. Reinstall panels or covers and close doors when service is finished and before
starting engine.
