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-

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
