• Protect your eyes with specially designed protective
glass (DIN grade 9-10). Use gloves and dry protec-
tive clothing that is free from oil and grease so that
the skin is not exposed to the ultraviolet rays from
the arc.
• Do not use the welding machine to thaw pipes.
Note!
• The light rays from the arc can damage the eyes and
cause burns to the skin.
• Arc welding creates sparks and droplets of melted
metal, the welded work piece begins to smoulder
and remains very hot for a relatively long time.
• Arc welding releases vapours that are potentially
harmful. Any electric shock can be potentially fatal.
• Do not come within 15 m of the arc.
• Protect yourself (and bystanders) in the vicinity from
the potentially hazardous effects of the electric arc.
• Warning: Depending on the conditions of the mains
power connection at the welding machine connec-
tion point, this can lead to disturbances in the mains
for other consumers.
Attention!
Overloaded mains supplies and circuits can cause dis-
turbances for other consumers while welding.
In case of doubt, the electricity supplier is to be con-
sulted.
Sources of danger when arc welding
A series of hazard sources can arise when arc welding.
It is therefore particularly important for the welder to
observe the following rules in order not to endanger
themselves and others and to avoid injuring persons
and damaging the device.
• Work on the mains voltage side, e.g. on cables, con-
nectors, sockets, etc., may only be carried out by a
specialist. This applies in particular when creating
intermediate cables.
• In the event of an accident, disconnect the welding
power source from the mains immediately.
• If electrical contact voltages occur, switch off the de-
vice immediately and have it checked by a specialist.
• Always ensure that the electrical contacts on the
welding current side are good.
• Always wear insulated gloves on both hands when
welding. These protect rays electric shocks (off-load
voltage of the welding current circuit), harmful rays
(heat and UV rays) and smouldering metal and slag
splashes.
• Wear sturdy, insulated footwear; the shoes should
also insulate when wet. Low shoes are not suitable
as smouldering metal drops that fall cause burns.
• Wear suitable clothing, no synthetic clothing.
• Do not look into the arc with unprotected eyes, only
use a welding shield with protective glass in accord-
ance with DIN. The arc also emits UV rays in ad-
dition to light and heat rays which cause glare and
burns. These invisible ultraviolet rays cause very
painful conjunctivitis that is only noticeable a few
hours later if the protection is insufficient. Further-
more, UV rays cause harmful, sunburn-like effects
to unprotected parts of the body.
• Also, persons in the vicinity of the electric arc must
be advised of the hazard and equipped with the nec-
essary protective equipment. Protective partitions or
walls may have to be erected.
• When welding, especially in small rooms, ensure
that there is a sufficient supply of fresh air as smoke
and harmful gases form.
• Welding work may not be carried out on containers
in which gases, fuels, mineral oils or the like are
stored, even if they have been empty for a long pe-
riod as there is a risk of explosion due to residues.
• Special regulations apply in areas where there is a
risk of fire and explosion.
• Welded joints that are exposed to high stresses and
must meet safety requirements may only be carried
out by specially trained and certified welders. Exam-
ples are: Pressure vessels, rails, trailer couplings,
etc.
• Arc rays can damage the eyes and the skin. Wear a
hat and safety goggles.
• Wear hearing protection and shirts with high, closed
collars.
• Wear welding helmets and ensure that the filter set-
tings are appropriate.
• Wear full body protection.
m Attention
• It must be ensured that the protective conductor in
electrical systems or devices can be destroyed by
the welding current in the event of negligence, e.g.
the earth clamp is placed on the welding machine
housing which is connected to the protective con-
ductor of the electrical system. The welding work is
carried out on a machine with a protective conduc-
tor connection. It is therefore possible to weld to the
machine without having to attach the earth clamp to
it.
