1 SAFETY

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.

WARNING!

Before use, read and understand the instruction manual and follow

all labels, employer´s safety practices and Safety Data Sheets

(SDSs).

1.2 Safety precautions

Users of ESAB equipment have the ultimate responsibility for ensuring that anyone who works on or

near the equipment observes all the relevant safety precautions. Safety precautions must meet the

requirements that apply to this type of 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 operation of the 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 equipment must be familiar with:

• its operation

• location of emergency stops

• its function

• relevant safety precautions

• welding and cutting or other applicable operation of the equipment

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 or work is started with the

equipment

3. The workplace must:

• be suitable for the purpose

• be free from drafts

4. Personal safety equipment:

• Always wear recommended personal safety equipment, such as safety

glasses, flame-proof clothing, safety gloves

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

which could become trapped or cause burns

5. General precautions:

• Make sure the return cable is connected securely

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

qualified electrician

1  SAFETY

0446 455 001 -5- © ESAB AB 2021

• Appropriate fire extinguishing equipment must be clearly marked and

close at hand

• Lubrication and maintenance must not be carried out on the equipment

during operation

WARNING!

Wire feeders are intended to be used with power sources in MIG/MAG mode only.

If used in any other welding mode, such as MMA, the welding cable between wire feeder and

power source must be disconnected, or else the wire feeder becomes live or energized.

If equipped with ESAB cooler

Use ESAB approved coolant only. Non-approved coolant might damage the equipment and jeopardize

product safety. In case of such damage, all warranty undertakings from ESAB cease to apply.

Recommended ESAB coolant ordering number: 0465720002.

For ordering information, see the "ACCESSORIES" chapter in the instruction manual.

WARNING!

Arc welding and cutting can be injurious to yourself and others. Take precautions when

welding and cutting.

ELECTRIC SHOCK - Can kill

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

or wet clothing

• Insulate yourself from work and ground.

• Ensure your working position is safe

ELECTRIC AND MAGNETIC FIELDS - Can be dangerous to health

• Welders having pacemakers should consult their physician before welding.

EMF may interfere with some pacemakers.

• Exposure to EMF may have other health effects which are unknown.

• Welders should use the following procedures to minimize exposure to

EMF:

○ Route the electrode and work cables together on the same side

of your body. Secure them with tape when possible. Do not

place your body between the torch and work cables. Never coil

the torch or work cable around your body. Keep welding power

source and cables as far away from your body as possible.

○ Connect the work cable to the workpiece as close as possible

to the area being welded.

FUMES AND GASES - Can be dangerous to health

• Keep your head out of the fumes

• Use ventilation, extraction at the arc, or both, to take fumes and gases

away 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

NOISE - Excessive noise can damage hearing

Protect your ears. Use earmuffs or other hearing protection.

1  SAFETY

0446 455 001 -6- © ESAB AB 2021

MOVING PARTS - Can cause injuries

• Keep all doors, panels and covers closed and securely in place. Have only

qualified people remove covers for maintenance and troubleshooting as

necessary. Reinstall panels or covers and close doors when service is

finished and before starting engine.

• Stop engine before installing or connecting unit.

• Keep hands, hair, loose clothing and tools away from moving parts.

FIRE HAZARD

• Sparks (spatter) can cause fire. Make sure therefore that there are no

inflammable materials nearby

• Do not use on closed containers.

HOT SURFACE - Parts can burn

• Do not touch parts bare handed.

• Allow cooling period before working on equipment.

• To handle hot parts, use proper tools and/or insulated welding gloves to

prevent burns.

MALFUNCTION - Call for expert assistance in the event of malfunction.

PROTECT YOURSELF AND OTHERS!

CAUTION!

This product is solely intended for arc welding.

CAUTION!

Class A equipment is not intended for use in residential locations

where the electrical power is provided by the public low-voltage

supply system. There may be potential difficulties in ensuring

electromagnetic compatibility of class A equipment in those

locations, due to conducted as well as radiated disturbances.

NOTE!

Dispose of electronic equipment at the recycling facility!

In observance of European Directive 2012/19/EC on Waste

Electrical and Electronic Equipment and its implementation in

accordance with national law, electrical and/or electronic equipment

that has reached the end of its life must be disposed of at a

recycling facility.

As the person responsible for the equipment, it is your

responsibility to obtain information on approved collection stations.

For further information contact the nearest ESAB dealer.

ESAB has an assortment of welding accessories and personal protection equipment for

purchase. For ordering information contact your local ESAB dealer or visit us on our website.
