1 SAFETY

Users of ESAB welding equipment have the ultimate responsibility for ensuring that

anyone who works on or near the equipment observes all the relevant safety pre-

cautions. Safety precautions must meet the requirements that apply to this type of

welding equipment. The following recommendations should be observed in addition

to the standard regulations that apply to the workplace.

All work must be carried out by trained personnel well-acquainted with the oper-

ation of the welding equipment.

Incorrect operation of the equipment may lead to hazardous situations which can

result in injury to the operator and damage to the equipment.

1. Anyone who uses the welding equipment must be familiar with:

its operation

location of emergency stops

its function

relevant safety precautions

welding

2. The operator must ensure that:

no unauthorised person is stationed within the working area of the

equipment when it is started up.

no-one is unprotected when the arc is struck

3. The workplace must:

be suitable for the purpose

be free from draughts

4. Personal safety equipment

Always wear recommended personal safety equipment, such as safety

glasses, flame-proof clothing, safety gloves. Note! Do not use safety

gloves when replacing wire.

Do not wear loose-fitting items, such as scarves, bracelets, rings, etc.,

which could become trapped or cause burns.

5. Protection against other risks

Dust particles of a certain size can be harmful to man. A ventilation system

and extractor should therefore be provided to eliminate this risk.

6. General precautions

Make sure the return cable is connected securely.

Work on high voltage equipment may only be carried out by a qualified

electrician.

Appropriate fire extinquishing equipment must be clearly marked and close

WARNING, RISK OF CRUSHING!

Do not use safety gloves when replacing wire, feed rollers and wire bobbins.

WARNING

ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND

OTHERS. TAKE PRECAUTIONS WHEN WELDING. ASK FOR YOUR

EMPLOYER'S SAFETY PRACTICES WHICH SHOULD BE BASED ON MANU-

ELECTRIC SHOCK - Can kill

Install and earth the welding unit in accordance with applicable standards.

Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet

clothing.

Insulate yourself from earth and the workpiece.

Ensure your working stance is safe.

FUMES AND GASES - Can be dangerous to health

Keep your head out of the fumes.

Use ventilation, extraction at the arc, or both, to keep fumes and gases from

your breathing zone and the general area.

ARC RAYS - Can injure eyes and burn skin

Protect your eyes and body. Use the correct welding screen and filter lens and

wear protective clothing.

Protect bystanders with suitable screens or curtains.

FIRE HAZARD

Sparks (spatter) can cause fire. Make sure therefore that there are no inflam-

mable materials nearby.

NOISE - Excessive noise can damage hearing

Protect your ears. Use ear defenders or other hearing protection.
