SAFETY INFORMATION
Please note
IMPORTANT
Only use this appliance for the purpose for which it is de-
signed 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 regu-
lations.
• Repairs and/or maintenance work may only be carried
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 correctly connected to the mains
supply (see 6.). Do not subject the mains lead to any
tensile stress. Unplug the appliance before you change
its position.
• 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 dangerous conditions
and reduce the quality of the welding work.
• Arc welding generates sparks, molten metal particles
and smoke, so the following is required: Remove all in-
fl ammable substances and/or materials from the work-
ing area.
• Ensure that there is adequate ventilation.
• Do not weld on tanks, vessels or pipes that have con-
tained infl ammable liquids or gases. Avoid all direct con-
tact with the welding circuit; the idling voltage between
the electrode tongs and the earth terminal may be dan-
gerous.
• Do not weld in dusty places.
6
• Do not store or use the appliance in wet or damp condi-
tions or in the rain.
• Protect your eyes with specially designed goggles (DIN
level 9-10), which you can attach to the supplied 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 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 unpro-
tected.
• Protect yourself (and others around you) against the
possible hazardous effects of the arc.
• Warning: Depending on the mains connection condi-
tions 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 con-
sumers 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 exam-
ple on cables, plugs, sockets, etc., performed only by
trained electricians. This particularly applies to confi g-
uring 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 weld-
ing current side.
5. Wear insulating gloves on both hands for welding.
These offer protection from electric shocks (idling volt-
age 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 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 con-
junctivitis, 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 notifi ed of the dangers and provided with the
required protection; if necessary install safety walls.
