tions.
SAFETY INFORMATION
Please note

IMPORTANT

Only use this appliance for the purpose for which it
is designed and as described in these instructions:
Manual 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 constricted or placed next to a wall while it
is operating. Make sure that the appliance is cor-
rectly connected to the mains supply (see 6.). Do
not subject the mains lead to any tensile stress.
Unplug the appliance before you change its posi-
tion.
• Check the condition of the welding cables, the
electrode tongs and the earth terminals; wear on
the insulation and the live parts may result in dan-
gerous 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
voltage between the electrode tongs and the earth
terminal 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
clothing 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 mol-
ten 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
unprotected.
• 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 suf-
fer 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 dan-
ger. 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 ex-
ample on cables, plugs, sockets, etc., performed
only by trained electricians. This particularly ap-
plies 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
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.
