WORK-AREA SURFACES
Work benches or tables used during welding
MUST have fireproof surfaces.
WALL AND FLOOR PROTECTION
The walls and flooring surrounding the cut envi-
ronment must be shielded using non-flamma-
ble materials. This not only reduces the risk of fire but also avoids
damage to the walls and floors during cut processes.
EXTINGUISHER
Place an approved and appropriately-sized fire 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.
CLEAN ENVIRONMENT
Remove all flammable materials away from
the work environment.
SERIOUS DANGER ! 1
NEVER cut in confined spaces (e.g. in a container vehicle, a cistern
or a storeroom etc.) where toxic, inflammable or explosive materials
are, or have been, located or stored. Cisterns, in particular, may still
contain toxic, flammable or explosive gases and vapours years after
they have been emptied.
SERIOUS DANGER ! 2
NEVER cut a cistern that contains (or has stored) toxic, inflam-
mable or explosive materials. They could still contain toxic,
flammable or explosive gases and vapours years after they
have been emptied. If you are obliged to weld a cistern, ALWAYS
passivate it by filling it with sand or a similar inert substance
before starting any work.
SERIOUS DANGER! 3
NEVER use the Welder to melt frozen water
pipes.
VENTILATION
VENTILATION
Together with the previous instructions, the following pre-
cautions should be strictly observed
WELDING ENVIRONMENT VENTILATION
Ventilate the cut environment carefully. Maintain sufficient air-flow
to avoid toxic or explosive gas accumulation. Cut processes on
certain kinds or combinations of metals can generate toxic fumes.
In the event of this happening, use air-supply respirators. BEFO-
RE cut, read and understand the welding alloy safety provisions.

ELECTRIC SHOCK
Together with the previous instructions, the following pre-
cautions should be strictly observed to reduce the risk of
electric shock
ELECTRIC SHOCK INJURY
DO NOT touch a person suffering from electric shock if
he/she is still in contact with the cables. Switch the mains
power source off immediately THEN provide assistance.
CABLE CONTACT
Do not tamper with power cables if the mains power is still
switched on.
CABLE AND PLUG PRECAUTIONS
Check the power supply cable, plug and wall-socket regularly.
This is particularly important if the equipment is relocated often.
REPAIRS
Never attempt to repair the Welder yourself. The result would
not only cause warranty cancellation but also high danger risks.
OPENING OF THE AREAS ACCESSIBLE TO THE OPERATOR
Always make sure that the machine is disconnected from the
mains before performing the maneuvers of ordinary mainte-
nance procedures contained in this manual.
ELECTROMAGNETIC COMPATIBILITY
Check no power supply cables, telephone cables or other
electrical items (e.g. computer cables, control lines etc.) are
in the vicinity of the cut.
Check there are no telephones, televisions, computers or other
transmission devices close to the equipment.
Make sure that people with pace-makers are not in the imme-
diate vicinity of the equipment.
Do not use the equipment in hospitals or medical environ-
ments (including veterinary surgeries). Make especially sure
there is no electrical medical equipment being used close to whe-
re equipment is being done.
Should the equipment interfere with other apparatus, take the
following precautionary measures:
1. Check the equipment 's side panels are securely fastened.
2. Shorten the power supply cables.
Place EMC filters between the Welder and the power source.
EMC compatibility : CISPR 11, Group 2, Class A.
