This welding machine is intended for
welding metals.
It conforms to all relevant regulations at
the time of delivery.
This welding machine is intended for
operation by professional arc welders or
specialists of similar qualificationw.
Permissible welding processes:
− TIG DC (Tungsten-Inert-Gas),
for all metals, except aluminium
− Stick electrode welding
For TIG welding it must be ensured that
the shielding gas cover is not blown
away by air draft.
For machine performance see "Techni-
cal Specifications".
Any other use is not as specified and
prohibited.
Unspecified use, modification of the
machine or use of parts not tested and
approved by the equipment manufac-
turer could cause unforeseeable dam-

ENGLISH
B
Danger!
Electric potential!
•
Use the machine indoors and in dry
environment only.
•
Connect machine only to a properly
earthed outlet.
If in doubt check with a qualified
electrician!
•
Service and repairs to the machines
must only be made by qualified elec-
tricians.
•
Unplug before removing
machine's cover.
A
Danger!
•
Wear sufficient protective clothing
when welding.
•
Always use a welding shield or hel-
met and welder's gloves.
They provide protection against
sparks and arc radiation.
•
All metal fumes are detrimental to
health!
When working indoors ensure suffi-
cient ventilation and extraction in
order to not exceed the max. per-
missible workplace pollutant con-
centration.
The fumes of lead, cadmium, cop-
per, chromium, nickel, zinc and
beryllium are particularly harmful!
A
Caution!
•
Never weld earthed metal.
This will prevent possible damage to
the protective earth conductors by
stray welding currents.
•
Never use the welding machine for
thawing pipes.
•
Always attach the welding return
cable directly to the weld metal and
as close as possible to the welding
spot.
•
Always carry the welding machine at
the carrying strap when transport-
ing it.
•
Special care is required when work-
ing near computers, electronically
controlled equipment or in the prox-
imity of magnetic data media (sound
recording tapes, floppy disks, data
recording tapes, credit cards, etc.).
The arc start can cause misfunction
of this type of equipment or data
loss.
