Safety instructions

Safety/1

For Your Safety:

Warning: Observe accident prevention regulations!

Ignoring the following safety procedures can be fatal.

•

Before undertaking welding tasks, put on prescribed dry protective clothing, e.g. gloves.

•

Protect eyes and face with protective visor.

Electric shocks can be fatal

•

The machine may only be connected to correctly earthed sockets.

•

Only operate with intact connection lead including protective conductor and safety plug.

•

An improperly repaired plug or damaged mains cable insulation can cause electric shocks.

•

The machine may only be opened by qualified and authorised personnel.

•

Before opening, pull out the mains plug. Switching off is not sufficient. Wait for 2 minutes

until capacitors are discharged.

•

Always put down welding torch, stick electrode holder in an insulated condition.

Even touching low voltages can cause you to jump and lead to accidents, so:

•

Secure yourself from falls before working on platforms or scaffolding.

•

When welding, operate handle earth tongs, torch and workpiece properly, not in ways for

which they are not intended. Do not touch live parts with bare skin.

•

When welding, operate handle earth tongs, torch and workpiece properly, not in ways for

which they are not intended. Do not touch live parts with bare skin.

•

Never use torches or earth cables with damaged insulation.

Smoke and gases can lead to breathing difficulties and poisoning.

• Do not breathe in smoke and gases.

• Ensure that there is sufficient fresh air.

• Keep solvent vapours away from the arc radiation area. Chlorinated hydrocarbon fumes can

be converted into poisonous phosgene by ultraviolet radiation.

Workpiece, flying sparks and droplets are hot

• Keep children and animals well away from the working area. Their behaviour is unpredictable.

• Move containers with inflammable or explosive liquids away from the working area.

There is a danger of fire and explosion.

• Never heat explosive liquids, dust or gases by welding or cutting. There is also a danger of

explosions when apparently harmless substances develop high pressures in enclosed

containers by heating.

Take care to avoid fire hazards

• Any kind of fire hazards must be avoided. Flames can form e.g. when sparks are flying, when

parts are glowing or hot slag is present.

• A constant check must be kept on whether fire hazards have been created in the working area.

• Highly inflammable objects, such as matches and cigarette lighters for example, must not be

carried in trouser pockets.

• You must ensure that fire extinguishing equipment - appropriate to the welding process - is

available close to the welding work area and that easy access is possible.

Safety instructions

Safety/2

Take care to avoid fire hazards

•

Containers in which fuels or lubricants have been present must be thoroughly cleaned before

welding begins. It is not sufficient simply for the receptacle to be empty.

•

After a workpiece has been welded, it must only be touched or brought into contact with

inflammable material when it has cooled down sufficiently.

•

Loose welding connections can completely destroy protective conductor systems of interior

installations and cause fires. Before beginning welding work, ensure that the handle earth

tongs are properly fixed to the workpiece or welding bench and that there is a direct electrical

connection from the workpiece to the power source.

Noise exceeding 70 dBA can cause permanent hearing damage

•

Wear suitable earmuffs or plugs.

•

Ensure that other people who spend time in the working area are not inconvenienced by the

noise.

Secure gas cylinder

•

Place shielding gas cylinders in the holders provided for them and secure with safety chains.

•

Take care when handling cylinders; do not throw or heat, guard against them toppling over!

•

When moving by crane, take off the gas cylinder from the welding machine.

Caution: Interference by electric and electromagnetic fields can be caused by the welding

machine or by the high-voltage pulses of the ignition unit..

•

As laid down in Electromagnetic Compatibility Standard EN 50199, the machines are intended f

use in industrial areas; if they are operated e.g. in residential environments problems can occur

ensuring electromagnetic compatibility.

• The functioning of heart pacemakers can be adversely affected when you are standing near th

e

welding machine.

• Malfunctioning of electronic equipment (e.g. EDP, CNC equipment) in the vicinity of the

welding location is possible.

• Other mains supply leads, trip leads, signal and telecommunications leads above, under and

near the welding device may be subject to interference.

Warning: Electromagnetic interference must be reduced to such a level that it no longer

constitutes interference.

Possible reduction measures:

• Welding equipment should be serviced regularly. (see Sect. Maintenance and care)

• Welding leads should be as short as possible and run closely together on or near to the

ground.

• Selective shielding of other leads and equipment in the environment can reduce radiation

Caution: Repairs and modifications may only be carried out by authorised, trained,

specialist personnel.

The warranty becomes null and void in the event of unauthorised interference.

Our operating instructions will provide you with an introduction into the safe use of the

machine.

Therefore please read them closely and only start work when you are familiar with them.
