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:

•Safeguard yourself against falls, e.g. from a platform or scaffolding.

•When welding, operate earth tongs, torch and workpiece properly, not in ways for which they

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

•Only replace electrodes when wearing dry gloves.

•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 exposive liquids away from the working area.

There is a danger of fire and explosion.

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

explosion if apparently harmless substances in closed containers are able to build up excess

pressure when they are heated.

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 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 electrical and electromagnetic fields is possible e.g. from the

welding machine or from the high-voltage pulses of the ignition unit.

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

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

occur in ensuring electromagnetic compatibility.

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

the 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 machines should be regularly maintained (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.

Safety instructions

Safety /3

Transport and set-up

•Machines may only be moved and operated in an upright position.

•Before moving, pull out mains plug and place on the machine.

•Secure high-pressure shielding gas cylinder with safety chain to prevent it from toppling

over.

Environmental conditions:

The welding machine can be operated in a location where there is no risk of explosion at

•an ambient temperature of -10°C (plasma machines 0°C) to +40°C and

•a relative air humidity up to 50% at 40°C.

•where the surrounding air is free of unusual amounts of dust, acids, corrosive gases or

substances etc., insofar as they do not occur during welding.

Examples of unusual operating conditions:

Unusual corrosive smoke, vapour, excessive oil vapour, unusual vibrations or jolts, excessive

quantities of dust such as grinding dust etc., severe weather conditions, unusual conditions near

the coast or on board ship.

•When setting up the machine, ensure that air inlets and outlets are unobstructed.

The machine is tested to Protection Standard IP23, i.e.:

•Protection against penetration of solid foreign bodies ∅> 12mm,

•Protection against water spray up to an angle of 60° to the vertical.

Notes on the use of these operating instructions

These operating instructions are arranged in Sections.

To help you find your way around more quickly, in the margins you will occasionally see, in addition

to sub-headings, icons referring to particularly important passages of text which are graded as

follows depending on their importance:

(Note): Applies to special technical characteristics which the user must note.

(Warning): Applies to working and operating procedures which must be followed

precisely to avoid damaging or destroying the machine.

(Caution): Applies to working and operating procedures which must be followed

precisely to avoid endangering people and includes the “Warning” symbol.

About this machine manufactured in inverter technology

Congratulations.

You have purchased a modern and efficient welding machine in inverter technology.

In contrast to conventional power sources, it does not operate with 50Hz but with a 25kHz primary

driven transistor current source.

The advantages of inverter technology:

•Less effort in changing to another workplace because the machine dimensions and weight are

substantially reduced.

•Lower power consumption and smaller mains ratings by high efficiency (no losses).

•No need for expensive compensating equipment by a high cos phi and a correspondingly

smaller reactive current draw from the mains.

•Functional safety by robust construction, highly integrated electronic circuitry.

•High operating safety by thermal monitors in the power circuit.

•High control dynamics for the welding process. Therefore excellent welding and ignition results

and absolute reproducibility of all welding parameters.

•Welding result independent of mains voltage fluctuations.

•Easily serviced design by the use of modern, modular technology.

The

powerSinus

– Series:

The machines with

powerSinus series

have a built-in electronic switching unit which restricts the

current spikes coming from the mains supply and produces a pure Sinus-form of mains current. As

a result 200Amps welding current can be achieved from a 230V plug fused at 16Amps with

a cos phi of 1.
