1 SAFETY PRECAUTIONS

1.1 Meaning of symbols

As used throughout this manual: Means Attention! Be Alert!

DANGER!

Means immediate hazards which, if not avoided, will result in immediate,

serious personal injury or loss of life.

WARNING!

Means potential hazards which could result in personal injury or loss of

life.

CAUTION!

Means hazards which could result in minor personal injury.

1.2 Safety guidance and information

WARNING!

Before use, read and understand the instruction manual

and follow all labels, employer's safety practices and Safety

Data Sheets (SDSs).

WARNING!

These Safety Precautions are for your protection. They summarise 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 the Safety Precautions could

result in injury or death.

PROTECT YOURSELF AND OTHERS

Some welding, cutting and gouging processes are noisy and require

hearing 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/or 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.

1 SAFETY PRECAUTIONS

0463 479 001

- 6 -

4. Wear flameproof gauntlet-type gloves, heavy long-sleeve shirt, cuffless pants,

high-topped shoes, and a welding helmet or cap for personal protection; in order to

protect against arc rays and hot sparks or hot metal. A flameproof apron may also be

desirable as additional 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 (closed) and open pockets should be 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. Post warning signs advising others not to watch the welding arc

or be in direct exposure to the active arc without proper protection.

7. Use goggles or face shields 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.

FIRES AND EXPLOSIONS

The 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 an approved 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. Follow the "hot work" procedures for the location. This can include a fire watch person

who monitors the sparks during the work, the requirement for a formal work permit and

the surveillance of the scene for an extended period of time to ensure no smoldering

fires are developing.

5. Do not weld, cut, or perform other hot work until the work piece has been completely

cleaned so that there are no substances on or in the work piece which might produce

flammable or toxic vapors. Do not perform hot work on closed containers, they may

explode.

6. 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.

7. Do not use equipment beyond its ratings. For example, an overloaded welding cable

can overheat and create a fire hazard.

8. 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 between live electrical parts and earth 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. All ground points should be verified with periodic testing by an electrician.

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.

1 SAFETY PRECAUTIONS

0463 479 001

- 7 -

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 an effective insulation layer, such as dry boards, 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. Welders with medical 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

together 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, smoke, and vapors. Do not breathe the smoke,

fumes, and gases that are generated by welding processes.

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. Orient the ventilation to draw smoke, fumes, and vapors in a direction away from the

welding operator. Position ventilation suction to pull welding fumes and smoke from

the far side of the work area if possible

4. Provide general ventilation for the surrounding work area if there is a risk of workers or

other persons beyond the immediate work area getting exposed to significant welding

fumes. Monitor the fugitive fumes and smoke for potential collateral exposures. Install

appropriate ventilation controls or cease surrounding activity if fumes become an

exposure issue outside of the immediate work area

5. Do not operate near degreasing and spraying operations. The heat or arc can react

with chlorinated hydrocarbon vapors or liquids to form phosgene, a highly toxic gas,

and other irritant gases.

1 SAFETY PRECAUTIONS

0463 479 001

- 8 -

6. 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.

7. Respiratory protection is required if worker respiratory exposures to fumes exceed

recommended thresholds. Those thresholds can only be accurately measured through

standardized industrial hygiene sampling protocols. Seek the assistance of specialists

if your work causes respiratory exposures or you have other exposure concerns.

8. Refer to ANSI/ASC Standard Z49.1 for specific ventilation recommendations.

9. WARNING: This product when used for welding or cutting, typically produces fumes or

gases which contain chemicals known to the State of California that can 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 the cylinder valve or relief device can injure or kill.

Therefore:

1. Locate cylinders away from heat, sparks and flames.

2. Inspect all connections before use to detect and correct any leaks or system defects.

Use soapy water as a test if you suspect a leak but have difficulty confirming its

location or existence.

3. Never strike an arc on a cylinder. Handle cylinders with care and avoid jolts and

impacts to cylinders; regardless of if they are empty, partial, or full.

4. Secure all cylinders in a way that prevents them from falling and potentially doing

damage to the valve, regulator, or attachments. Typically, this requires the use of a

secure strap or chain at an appropriate height that helps to prevent the cylinder from

falling over.

5. 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.

6. Never secure cylinders to work tables or fixtures where they may become part of an

electrical circuit.

7. 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 the engine or drive systems before installing or connecting a 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. Monitor the battery to prevent accidental reconnection

before the work is done and the area is clear for restarting.

5. Keep hands, hair, loose clothing and tools away from moving parts. Do not use gloves

near moving parts.

6. Reinstall panels or covers and close doors when service is finished and before starting

engine.
