Srelevant safety precautions

Swelding and cutting

2. The operator must ensure that:

Sno unauthorized person is stationed within the working area of the equipment when it is

started up.

Sno-one is unprotected when the arc is struck

3. The workplace must:

Sbe suitable for the purpose

Sbe free from drafts

4. Personal safety equipment

SAlways wear recommended personal safety equipment, such as safety glasses, flame-proof

clothing, safety gloves. Note! Do not use safety gloves when replacing wire.

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

SInstall and earth the unit in accordance with applicable standards.

SDo not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.

SInsulate yourself from earth and the workpiece.

SEnsure your working stance is safe.

FUMES AND GASES - Can be dangerous to health

SKeep your head out of the fumes.

SUse 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.

SProtect your eyes and body. Use the correct welding screen and filter lens and wear protective

clothing.

SProtect bystanders with suitable screens or curtains.

FIRE HAZARD

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

NOISE - Excessive noise can damage hearing

SProtect your ears. Use earmuffs or other hearing protection.

SWarn bystanders of the risk.

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

PROTECT YOURSELF AND OTHERS!

CAUTION

This product is solely intended for arc welding.

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.

4.3 Mains supply

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.
