Potential hazards

There are a number of potential hazards that can occur during arc welding.

It is therefore particularly important for the welder to comply with the

following rules to avoid endangering himself or others and prevent injuries

or damage to the appliance.

▯ Do not use this ﬂux-core welder on a surface that is inclined by more

than 10°.

▯ Work on the voltage side, e.g. on cables, plugs, sockets, etc., may only

be carried out by qualiﬁed specialists. This applies especially to the

ﬁtting of intermediary cables.

▯ In the event of an accident, disconnect immediately from the welding

power source.

▯ If electrical contact voltages occur, switch oﬀ the appliance immediately

and have it checked by a qualiﬁed specialist.

▯ Always ensure good electrical contacts on the welding current side.

▯ Always wear insulating gloves on both hands during welding work.

These protect the user from electric shock (no-load voltage of the welding

current circuit), harmful radiation (heat and UV radiation) as well as

from incandescent metal and splashes of slag.

▯ Wear sturdy insulating shoes (should also be waterproof). Loafers are

not suitable as falling incandescent metal droplets can cause burns.

▯ Wear suitable clothing, no synthetic ﬁbres.

▯ Do not look into the electric arc without eye protection; always use the

welding mask with the prescribed protective glass as per DIN. In addition

to the light and heat radiation, which can dazzle and/or cause burns,

the electric arc also emits UV radiation. If not properly protected, this

invisible ultraviolet radiation can cause a very painful conjunctivitis that

is not apparent until several hours later. In addition, this UV radiation

can cause sunburn-like eﬀects on unprotected parts of the body.

▯ Any persons in the vicinity of the electric arc or helpers must be appraised

of the dangers and be equipped with the necessary protective equip-

ment. If necessary, put up protective walls.

▯ No welding work may be carried out on containers that have been

used for storing gases, fuels, mineral oils or similar – even if they have

been empty for a long time – as possible residues may present a risk of

explosion.

▯ Special regulations apply in rooms where there is a risk of ﬁre or

explosion.

▯ Welded joints that are subject to heavy stress loads and are required

to comply with safety requirements may only be carried out by trained

and qualiﬁed welders. Examples of this are: pressure vessels, running

rails, tow bars, etc.

Risk of injury due to electric shock

When there is no electric arc, there is a nominal no-load voltage of U

be-

tween the earth clamp and the ﬂow nozzle. This voltage can be potentially

fatal if the welder touches the ﬂow nozzle, torch nozzle, welding wire or

the workpiece with his/her bare hands.

▯ It is important to bear in mind that the protective conductor in electrical

systems or appliances can be damaged by negligence by the welding

current:

e.g. the earth clamp is placed on the welder housing which is connect-

ed to the protective conductor of the electrical system. The welding

work is carried out on a machine with a protective conductor connec-

tion. It is also possible to weld the machine without attaching the earth

clamp to it. In this case, the welding current ﬂows from the earth clamp

via the protective conductor to the machine. The high welding current

can cause the protective conductor to melt.

▯ The supply to the mains socket must be secured as per regulations

(VDE 0100). In accordance with these regulations, only fuses or circuit

breakers with a corresponding wire cross section may be used (16 amp

circuit breaker). A too high fuse amperage can cause cable ﬁres or

building ﬁre damage.

Conﬁned spaces and hot rooms

▯ When working in conﬁned spaces or hot rooms, use insulated underlays,

ﬁller layers and gauntlets made of leather or a diﬀerent non-conduc-

tive material to insulate your body against the ﬂoor, walls, conductive

appliance parts and similar.

▯ When using welding transformers to weld in environments with in-

creased electrical risks, e.g. in conﬁned rooms with electrically conduc-

tive walls (boilers, pipes, etc.), in hot rooms (sweating through the work

clothes), the output voltage of the ﬂux-core welder in no-load operation

may not be higher than 48 V~ (eﬀective value). Due to its output volt-

age in no-load operation, the appliance may be used in this case.

Accident risks due to poor air supply in conﬁned

spaces

▯ Considerable quantities of smoke and gases are produced during

welding. Ensure that there is a suitable opening for the extraction of

smoke and gases. Never feed oxygen into the room. This increases the

risk of ﬁre.

Protective clothing

▯ While working, the welder must protect all body parts from radiation

and against burns by means of clothing and the welding mask.

▯ Wear gauntlets made of a suitable material (leather) on both hands.

They must be in perfect condition.

▯ To protect your clothes from ﬂying sparks and burns, wear a suitable

apron. If the type of work requires it, e.g. overhead welding, wear a

protective suit and, if necessary, also the corresponding headgear.

▯ The clothing worn and all accessories must comply with the guideline

“Personal protective equipment” (89/686/EEC).
