4 Safety precautions
Hazard-free working with the machine is only
possible if you read the operating and safety
instructions completely and strictly observe
them.
Please obtain practical training before using
the machine for the first time. Follow the ac
-
cident prevention regulations (UVV
1
).
Remove all solvents, degreasers, and other
flammable materials from the working area
before starting welding. Non-movable flam
-
mable materials must be covered. Only weld
if the ambient air contains no high concen-
trations of dust, acid vapours, gases or flam
-
mable substances. Special care must be
taken during repair work on pipe systems
and tanks which contain or have contained
flammable liquids or gases.
Never touch live parts inside or outside of the
housing.
Do not expose the machine to rain; do not
clean with sprays or steam jets.
Always use a protection shield when weld-
ing. 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 severed
while working, do not touch the cable, but im-
mediately pull out the mains plug. Never use
a machine if the mains cable is damaged.
Keep a fire extinguisher near the welding
area. Check the welding area for fire after
welding (see UVV
1)
).
Never try to disassemble the pressure re-
ducer. Replace the pressure reducer if faulty.

Only applicable for Germany. Can be ordered from
Carl Heymanns-Verlag, Luxemburger Str. 449,
50939 Köln.
The machine must be transported or set up
only on firm, level surfaces. The maximum
admissible angle of inclination 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 ground
cable immediately beside the weld point. Do not pass
the welding current through chains, ball bearings,
steel cables, grounding conductors, etc., as it could
cause these to melt.
Secure yourself and the welding machine when work-
ing in elevated or inclined areas.
The machine should be connected only to a properly
grounded mains supply. (Three-phase four-wire sys-
tem with grounded neutral conductor or single phase-
three-wire system with grounded neutral conductor)
socket and extension cable must have a functional
protective conductor.
Wear protective clothing, leather gloves and a leather
apron.
Protect the welding area with curtains or mobile
screens.
Do not use welding equipment to thaw out frozen wa-
ter pipes or lines.
In closed containers, under cramped conditions, and
in high electrical risk areas, only use machines with
the S sign.
When taking a break, switch off the machine and close
the valve on the gas cylinder.
Secure the gas cylinder with a chain to prevent it fall-
ing over.
Disconnect the mains plug from the mains before
changing the place of installation or making repairs to
the machine.
Please heed the safety regulations which apply to your
country. Subject to change.
