• Ensure adequate ventilation for welding, particular-
ly 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 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.
• The fuses on the supply cables to the mains sock-
ets must comply with the relevant regulations. To
comply with these regulations, only fuses or circuit
breakers suitable for the cross-section of the ca-
bles may be used. 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 as
slip-on gloves made of leather or other nonconduc-
tive materials to insulate your body against the floor,
walls, conductive parts of the machine and the like.
If you use small welding transformers for welding in
places with an increase electrical risk, for example
in constricted areas with conductive walls, (tanks,
pipes, etc.), in wet areas (which make work clothes
wet) and in hot areas (perspiration on work clothes),
the output voltage of the welding set when idling must
not exceed 85 V (effective value). Therefore, the ap-
pliance may not be used for these purposes because
its output voltage is higher than this.

Safety clothing
• While working, the welder must protect his entire
body from radiation and burns by wearing suitable
clothing and a face guard.
• Slip-on gloves made of a suitable material (leather)
must be worn on both hands. They must be in per-
fect condition.
• 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.
• The protective clothing used as well as all acces-
sories must be in compliance with the "Personal
safety equipment" EU Directive.
Protection from radiation and burns
• 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. Unauthor-
ized persons are to be kept away from the welding
work.
• The walls in the immediate vicinity of station-
ary workplaces should not have a light color or a
sheen. Windows up to head height are to be pro-
tected against radiation passing through them or
reflecting off them, for example by coating them
with a suitable paint.
Important information about the power connec-
tion
This equipment falls under Class A of the standard
EN 60974-10, i.e. it is not designed for use in resi-
dential areas in which the power supply is based on
a public low-voltage supply system because given
unfavorable conditions in the power supply the equip-
ment may cause interference. If you want to use the
equipment in residential areas in the which the power
supply is based on a public low-voltage supply sys-
tem, you must use an electromagnetic filter which re-
duces the electromagnetic interference to the point
where the user no longer notices any disturbance.
In industrial parks or other areas in which the power
supply is not based on a public low-voltage supply
system the equipment can be used without such a
filter.
General safety information
It is the user's responsibility to install and use the
equipment properly in accordance with the instruc-
tions issued by the manufacturer. If electromagnetic
interference is noticed, it is the user's responsibility
to eliminate said interference with the technical de-
vices mentioned in the section "Important information
about the power connection".
