OPERATING AND MAINTENANCE MANUAL
EXTINGUISHER
Place an approved and appropriately-sized
fi re extinguisher in the work environment.
Check its working order regularly (carry out scheduled
inspections) and ensure that all parties involved know
how to use one.
work environment.
vehicle, a cistern or a storeroom etc.) where toxic,
infl ammable or explosive materials are, or have been,
located or stored. Cisterns, in particular, may still
contain toxic, fl ammable or explosive gases and
vapours years after they have been emptied.
SERIOUS DANGER ! 2
NEVER weld a cistern that con-
tains (or has stored) toxic, infl am-
mable or explosive materials. They could still contain
toxic, fl ammable or explosive gases and vapours ye-
ars after they have been emptied. If you are obliged
to weld a cistern, ALWAYS passivate it by fi lling it with
sand or a similar inert substance before starting any
work.
VENTILATION
Together with the previous instructions, the following
precautions should be strictly observed.
WELDING ENVIRONMENT
VENTILATION
Ventilate the welding environment
carefully. Maintain suffi cient air-fl ow to avoid toxic or
explosive gas accumulation.
Welding processes on certain kinds or combinations
of metals can generate toxic fumes. In the event of
this happening, use air-supply respirators. BEFORE
welding, read and understand the welding alloy sa-
fety provisions.

SERIOUS DANGER! 3
NEVER use the Welder to
melt frozen water pipes.
PROTECTIVE WELDING GASES
Together with the previous instructions, the fol-
lowing precautions should be strictly observed
when welding with protective gases
GAS TYPES
These welders use only inert
(nonfl ammable) gases for wel
ding arc protection. It is important that the appro-
priate type of gas is chosen for the type of welding
being performed.
NUNIDENTIFIED GAS
CYLINDERS
NEVER use unidentifi ed gas
cylinders.
PRESSURE REGULATOR 1
NEVER connect the cylinder di-
rectly to the Welder. Always
use a pressure regulator.
PRESSURE REGULATOR 2
Check the regulator is perfor-
ming its function properly. Read
the regulator instructions carefully .
PRESSURE REGULATOR 3
Never lubricate any part of the
regulator.
PRESSURE REGULATOR 4
All regulators are designed for a
specifi c type of gas.
Check the regulator is appropriate for the protective
gas to be used.
DAMAGED GAS CYLINDERS
NEVER use damaged or faulty
cylinders.
CYLINDER RELOCATION
NEVER lift a gas cylinder by hol-
ding the regulator.
GAS CYLINDERS
Non esporre le bombole ad un
calore eccessivo, a scintille, a
scorie o alla fi amma.
GAS HOSE 1-2
Assicurarsi che il tubo del gas sia
in buono stato.
