Warning!

If the supply mains and circuits are overloaded,

other consumers may suffer interference during

the welding work. If you have any doubts, contact

your electricity supply company.

Sources of danger during arc welding

Hazard!

Arc welding results in a number of sources of

danger. It is therefore particularly important for

the welder to comply with the following rules so

as not to place himself or others in danger and to

avoid endangering people and equipment.

•

Have all work on the mains voltage system,

for example on cables, plugs, sockets, etc.,

performed only by trained electricians. This

particularly applies to configuring intermedia-

te cables.

•

If an accident occurs, disconnect the welding

power source from the mains immediately.

•

If electric touch voltages occur, switch off the

welding set immediately and have it checked

by an expert.

•

Always check for good electrical contacts on

the welding current side.

•

Wear insulating gloves on both hands for

welding. These offer protection from electric

shocks (idling voltage in the welding circuit),

harmful radiation (heat and UV radiation) and

from glowing metal and slag spatter.

•

Wear firm, insulated footwear. Your shoes

must also be suitable to protect you in wet

conditions. Open-toed footwear is not suita-

ble since falling droplets of glowing metal will

cause burns.

•

Wear suitable clothing, do not wear synthetic

clothes.

•

Do not look into the arc with unprotected

eyes, use only a welding screen with the

proper safety glass in compliance with DIN

standards. In addition to light and heat, which

may cause dazzling and burns, the arc also

gives off UV radiation. Without proper protec-

tion, this invisible ultraviolet radiation causes

very painful conjunctivitis, which will only be

noticeable several hours later. In addition,

UV radiation will cause harmful sunburn-type

symptoms on unprotected parts of the body.

•

Personnel or assistants in the vicinity of the

arc must also be notified of the dangers and

provided with the required protection; if ne-

cessary install safety walls.

•

Ensure adequate ventilation for welding,

particularly in small rooms since the process

causes smoke and harmful gases.

•

Do not carry out any welding work on tanks

that have been used to store gases, fuels,

mineral oil or the like, even if they have been

empty for a lengthy period of time, since any

residue will result in a danger of explosion.

•

Special regulations apply in areas where the-

re is a potential risk of fire and/or explosion.

•

Welds that are exposed to large stresses and

must comply with safety requirements may

only be completed by specially trained and

approved welders. Examples of such welds

include pressure vessels, rails, trailer hitches,

etc.

•

Notes:

It must be noted that the protective con-

ductor in electrical systems or equipment may

be destroyed by the welding current in the

event of negligence, for example if the earth

terminal is placed on the welding set casing

to which the protective conductor of the elec-

trical system is connected. The welding work

is completed on a machine with a protective

conductor connection. It is therefore possible

to weld on the machine without having con-

nected the earth terminal to it. In this case the

welding current will flow from the earth ter-

minal through the protective conductor to the

machine. The high welding current may cause

the protective conductor to melt.

•

The fuses on the supply cables to the mains

sockets must comply with the relevant regulati-

ons (VDE 0100). To comply with these regula-

tions, only fuses or circuit breakers suitable for

the cross-section of the cables may be used

(for earthing contact sockets max. 13 A fuses

or 13 A circuit breakers). The use of too high

a fuse may result in the cable burning and fire

damage to the building.
