Caution: Access to the the working
area and near the welding/cutting
operation generators is forbidden to
anyone wearing pacemakers or other
such electric devices.
At least once every 6 months make sure that
all electric appliances and accessories are well
insulated. Contact your supplier for more infor-
mation on the maintenance and repair of such
equipment.
Warning: Never touch the welding
cable or the electrode and the piece
which is being welded at the same
time.

ELECTRIC SYSTEM

Any intervention on electrical and electronic
equipment must be entrusted to qualified tech-
nicians capable of performing such operations.
Prior to connecting your appliance to the power
grid, make sure that the counter, the overload
and short-circuit protection devices, the so-
ckets, the plugs and the electric system as a
whole are compatible with the maximum power
of the appliance and its voltage (please check
the information on the plate) and in conformity
with the norms and regulations in force.
The ground single-phase or three-phase con-
nection (yellow/green cable) must be protected
by a medium or high-intensity differential-resi-
dual current device (sensitivity between 1 and
30 mA).
If the power cable is connected, the earth cable
(when present) must not be interrupted by the
protection device against electric shock. The
switch, if present, must be at "O"; the power ca-
ble, if not supplied, must be of the harmonized
type.
Ground all metal parts near the operator, using
cables that are thicker or as thick as the wel-
ding cables.
The protection class of the appliance is IP22S,
which means it prevents:
- manual contact with internal parts in high tem-
perature, which are moving or live;
- the introduction of solid bodies with more than
12 mm of diameter;
- protection against rain with maximum inclina-
tion of 15°.

FIRE PREVENTION

The working area must be in conformity with
safety regulations. This means that fire extin-
guishers must be installed, compatible with the
type of fire which may happen.
The ceiling, the floor and the doors must be
non-flammable. All combustible material must
be moved away from the workplace (Fig. 10).
If this is not possible, cover it with a fireproof
cover.
Before you start welding, ventilate all areas that
are potentially flammable.
Do not use the equipment in places with signi-
ficant concentrations of dust, flammable gas or
combustible liquid vapor.
The generator must be placed on solid, smooth
floor, and should never lean against walls.
Do not weld or cut containers filled with gaso-
line, lubricant or other flammable substances.
Do not weld or cut near ventilation ducts, gas
ducts or any other installation which could ac-
celerate the spreading of a fire.
After concluding the welding operation, always
make sure that no incandescent or burning ma-
terial has been left in the area.
Make sure the ground connection is good; a
defective ground connection may result in an
electric arc which can become the cause of a
fire.

PROTECTION GAS

Strictly follow all instructions of use and handling
provided by the gas supplier. In particular: the
areas of storage and use must be open and
ventilated, sufficiently away from the working
area and from sources of heat (< 50°C). Fix the
cylinders, protect them from impact and from
any technical accident.
Make sure the cylinder and the pressure gauge
correspond to the gas required for the welding
operation.
Never lubricate the cylinder taps and do not
forget to remove all gas from the same before
