• 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 should al-
so protect you in wet conditions. Opentoed footwear
is not suitable since falling droplets of glowing metal
will cause burns.
• 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 addi-
tion 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 radia-
tion will cause sunburn-type symptoms on unpro-
tected 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 necessary 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 dan-
ger of explosion.
• Special regulations apply in areas where there 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 com-
pleted by specially trained and approved welders.
Examples of such welds include pressure vessels,
rails, trailer hitches, etc.
• Note: It must be noted that the protective conduc-
tor in electrical systems of appliances may be de-
stroyed by the welding current in the event of neg-
ligence, for example if the earth terminal is placed
on the welding set casing to which the protective
conductor of the electrical system is connected. The
welding work is completed on a machine with a pro-
tective conductor connection. It is therefore possible
to weld on the machine without having connected
the earth terminal to it. In this case the welding cur-
rent will flow from the earth terminal through the pro-
tective conductor to the machine. The high welding
current may cause the protective conductor to melt.
• The fuses on the supply cables to the mains sock-
ets must comply with the relevant regulations (VDE
0100). To comply with these regulations, only fuses
or circuit breakers suitable for the cross-section of
the cables may be used (for earthing contact sock-
ets max. 16 A fuses or 16 A circuit breakers). The
use of too high a fuse may result in the cable burn-
ing and fire damage to the building.

Constricted and wet areas
When working in constricted, wet or hot areas, use
insulating supports and intermediate layers as well as
slip-on gloves made of leather or other nonconductive
materials to insulate your body against the floor, walls,
conductive parts of the machine and the like.
Safety clothing
1. While working, the welder must protect his entire
body from radiation and burns by wearing suitable
clothing and a face guard.
2. Slip-on gloves made of a suitable material (leather)
must be worn on both hands. They must be in per-
fect condition.
3. Suitable aprons must be worn to protect clothing
from sparks and burns. A safety suit and, if neces-
sary, head protection must be worn if required by the
type of work in question, e.g. overhead welding.
4. The protective clothing used as well as all accesso-
ries must be in compliance with the "Personal safety
equipment" EU Directive.
Protection from radiation and burns
1. Provide information about the risk to eyes at the
working site in the form of a poster with the wording
"Caution – do not look at the flames". Workplaces
are to be screened off wherever possible so that
personnel in the vicinity are protected. Unauthorized
persons are to be kept away from the welding work.
2. The walls in the immediate vicinity of stationary work-
places should not have a light color or a sheen. Win-
dows up to head height are to be protected against
radiation passing through them or reflecting off them,
for example by coating them with a suitable paint.
