WARNING

Read and understand the instruction manual before installing or operating.

Arc welding and cutting can be injurious to yourself and others. Take precausions when welding and
cutting. Ask for your employer's safety practices which should be based on manufacturers' hazard
data.

ELECTRIC SHOCK - Can kill

 Install and earth the 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 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.

FIRE HAZARD

 Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.

NOISE - Excessive noise can damage hearing

 Protect your ears. Use earmuffs or other hearing protection.
 Warn bystanders of the risk.

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

PROTECT YOURSELF AND OTHERS!

CAUTION

Read and understand the instruction manual before
installing or operating.

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.

ESAB can provide you with all necessary welding protection and accessories.

4 INSTALLATION

The installation must be executed by a professional.

Note

Mains supply requirements

High power equipment may, due to the primary current drawn from the mains supply, influence the
power quality of the grid. Therefore connection restrictions or requirements regarding the
maximum permissible mains impedance or the required minimum supply capacity at the interface
point to the public grid may apply for some types of equipment (see technical data). In this case it
is the responsibility of the installer or user of the equipment to ensure, by consultation with the
distrubution network operator if necessary, that the equipment may be connected.

4.1 Location

Position the power source such that its cooling air inlets and outlets are not
obstructed.

4.2 Mains power supply

Check that the welding power source is connected
to the correct voltage and that the correct fuse size
is used. A protective earth connection must be
made in accordance with regulations
