Additional Safety
Instructions for welders
Welders have many sources of danger. It
is therefore particularly important for the
welder to comply with the following rules
so as not to place themselves or others in
danger and to avoid endangering people
and equipment.
a) 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 intermediate cables.
b) If an accident occurs, disconnect the
welding power source from the mains
immediately.
c) If electric touch voltages occur, switch
off the welding set immediately and have
it checked by an expert.
d) Always check for good electrical
contacts on the welding current side.
GENERAL POWER TOOL SAFETY WARNINGS
e) 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.
f) Wear firm, insulated footwear. Your
shoes should also protect you in wet
conditions. Open- toed footwear is not
suitable since falling droplets of glowing
metal will cause burns.
g) Wear suitable clothing, do not wear
synthetic clothes.
h) Do not look into the arc with
unprotected eyes, use only a welding
safety shield 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 protection, this
invisible ultraviolet radiation causes very
painful conjunctivitis, which will only be
noticeable several hours later. In addition,
UV radiation will cause sunburn-type
symptoms on unprotected parts of the
body.
i) Personnel or assistants in the vicinity of
the arc must also be notified of the
dangers and provided with the required
protection; if necessary install safety walls.
j) Ensure adequate ventilation for
welding, particularly in small rooms
since the process causes smoke and
harmful gases.
k) 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.
