Important!
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.
Proper use
The machine is to be used only for its prescribed
purpose. Any other use is deemed to be a case of
misuse. The user / operator and not the
manufacturer will be liable for any damage or injuries
of any kind caused as a result of this.
Please note that our equipment has not been
designed for use in commercial, trade or industrial
applications. Our warranty will be voided if the
machine is used in commercial, trade or industrial
businesses or for equivalent purposes.
Sources of danger during arc welding
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.
1.
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.
2.
If an accident occurs, disconnect the welding
power source from the mains immediately.
3.
If electric touch voltages occur, switch off the
welding set immediately and have it checked by
an expert.
4.
Always check for good electrical contacts on the
welding current side.
5.
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.
6.
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.
7.
Wear suitable clothing, do not wear synthetic
clothes.
8.
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.
9.
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.
10. Ensure adequate ventilation for welding,
particularly in small rooms since the process
causes smoke and harmful gases.
11. 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.
12. Special regulations apply in areas where there is
a potential risk of fire and/or explosion.
13. 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.
14. Note: It must be noted that the protective
conductor in electrical systems of appliances
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 electrical
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 connected
the earth terminal to it. In this case the welding
current will flow from the earth terminal through
the protective conductor to the machine. The
high welding current may cause the protective
conductor to melt.
15. The fuses on the supply cables to the mains
sockets 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 sockets max. 16 A
fuses or 16 A circuit breakers). The use of too
high a fuse may result in the cable burning 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
