1.2 Safety precautions
WARNING!
These Safety Precautions are for your protection. They summarize precautionary information
from the references listed in the 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 the 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 look at 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, cuffless pants, 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 the 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 for long distances. Bystanders should also wear goggles over safety glasses.

1  SAFETY
0447 954 001 -4- © ESAB AB 2023
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. Move 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 coating 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 perform 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 work, inspect the work area to make sure there are no hot sparks or hot metal that
could cause a fire later. 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 earth system of the input power.
2. Connect the workpiece to a good electrical earth.
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 ground 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 earth 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  SAFETY
0447 954 001 -5- © ESAB AB 2023
1. Welders with pacemakers fitted should consult their doctor 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 minimize 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 the 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. Therefore:
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 in the 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 the
ventilation is not adequate. Stop work and take the 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 adapters. Maintain hoses and fittings in good
condition. Follow the manufacturer's operating instructions for mounting a 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.
