the machine, its proper use and safety precautions.
SAFETY INFORMATION
Please note
IMPORTANT
Only use this appliance for the purpose for which it is
designed and as described in these instructions: Man-
ual arc welding with coated electrodes.
Handling this system incorrectly may be hazardous for
persons, animals and property. The user of this system
is responsible for his/her own safety and for the safety
of others.
Read these operating instructions and follow all the
regulations.
• Repairs and/or maintenance work may only be car-
ried out by qualifi ed personnel.
• Use only the welding cables supplied.
• Ensure that the appliance is looked after properly.
• To ensure that suffi cient air can be drawn in through
the ventilation slits, the appliance should not be con-
stricted or placed next to a wall while it is operating.
Make sure that the appliance is correctly connected
to the mains supply (see 6.). Do not subject the
mains lead to any tensile stress. Unplug the appli-
ance before you change its position.
• Check the condition of the welding cables, the elec-
trode tongs and the earth terminals; wear on the
insulation and the live parts may result in danger-
ous conditions and reduce the quality of the welding
work.
• Arc welding generates sparks, molten metal parti-
cles and smoke, so the following is required: Re-
move all infl ammable substances and/or materials
from the working area.
• Ensure that there is adequate ventilation.

• Do not weld on tanks, vessels or pipes that have
contained infl ammable liquids or gases. Avoid all
direct contact with the welding circuit; the idling volt-
age between the electrode tongs and the earth ter-
minal may be dangerous.
• Do not weld in dusty places.
• Do not store or use the appliance in wet or damp
conditions or in the rain.
• Protect your eyes with specially designed goggles
(DIN level 9-10), which you can attach to the sup-
plied safety shield. Wear gloves and dry safety cloth-
ing that are not contaminated by any oil or grease to
ensure that your skin is not exposed to ultraviolet
radiation from the arc.
REMEMBER.
• The radiation from the arc can damage your eyes
and cause burns on skin.
• Arc welding generates sparks and droplets of molten
metal; the welded workpiece may start to glow and will
remain very hot for a relatively long period of time.
• Arc welding releases vapors that may be harmful.
Every electric shock is potentially fatal.
• Do not approach the arc within a radius of 15 m un-
protected.
• Protect yourself (and others around you) against the
possible hazardous effects of the arc.
• Warning: Depending on the mains connection con-
ditions at the connection point of the welding set,
other consumers connected to the mains may suffer
faults.
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.
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 com-
ply 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 ex-
ample on cables, plugs, sockets, etc., performed
only by trained electricians. This particularly applies
to confi guring 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 weld-
ing set immediately and have it checked by an ex-
pert.
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 fi rm, insulated footwear. Your shoes should
also protect you in wet conditions. Open- toed foot-
wear is not suitable since falling droplets of glowing
metal will cause burns.
