Cover flammable materials which can
not be moved. Only weld if the ambient
air contains no high concentrations of
dust, acidic vapours, gases or flamma-
ble substances. Special care must be
taken during repair work on pipe sys-
tems and tanks which contain or have
contained flammable liquids or gases.
Never touch live parts inside or outside
of the housing. Never touch welding
electrodes or live welding current parts
in a machine that is on.
Do not expose the machine to rain; do
not clean with sprays or steam jets.
Always use a protection shield when
welding. Warn anyone in the work area
about the dangers of arc rays.
Please use a suitable extraction system
for gases and cutting vapours.
Always wear breathing apparatus
whenever there is a risk of inhaling
welding or cutting fumes.
If the power cable is damaged or sev-
ered while working, do not touch the
cable, but immediately pull out the
mains plug. Never use a machine if the
mains cable is damaged.
Keep a fire extinguisher near the weld-
ing area.
Check the welding area for fire after
welding (see Accident prevention
Never try to disassemble the pressure
reducer. Replace the pressure reducer
if faulty.
The machine must be transported or
set up only on firm, level surfaces.
The maximum admissible angle of in-
clination for setting up or transporting
is 10°.
‰ Service and repair work may only be carried out
by a trained electrician.
‰ Ensure that there is good direct contact for the

chains, ball bearings, steel cables, grounding
conductors, etc., as it could cause these to melt.
‰ Secure yourself and the welding machine when
working in elevated or inclined areas.
‰ The machine should be connected only to a
