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
○ 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!
Arc welding and cutting can be injurious to yourself and others. Take precautions
when welding and cutting.
ELECTRIC SHOCK - Can kill
• Install and ground the unit in accordance with instruction manual.
• 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
0460 742 001 -6- © ESAB AB 2017
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 that there are no inflammable
materials nearby.
• Do not use on closed containers.
MALFUNCTION - Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!
CAUTION!
This product is solely intended for arc welding.
WARNING!
Do not use the power source for thawing frozen pipes.
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.
