2. GENERAL PRECAUTIONS

Welding, if not opportunely carried out, represent a risk for the safe-
ty of the operator and of all the people which are within the imme-
diate vicinities. It is recommended therefore, to observe some fun-
damental safety rules such as:
-Limit the exposed area to smoke and radiation coming from the
welding area by using special welding light screens (ANTI
REFLEX) or, if possible, reserve a proper room for these industrial
processes.
-Protect the body, in all its parts, with protective clothing and acces-
sories (masks, helmets, etc...) and if possible, clothing needs to be
adherent to the operator's body; use shoes with rubber soles in
order to be opportunely isolates.
-Limit the fumes and gas formation by using clean, not rusted and
not treated metal pieces; contrary, if not possible to operate as
above, is recommended the use of masks in order to favour the
operator's breathing. Vacuums and ventilation systems should be
built in order to grant a continuos air flow.
3. ELECTRICAL EMERGENCY NORMATIVES
-Avoid to work with cables that are in any way deteriorated and
make sure to correctly connect the AC phases and earth on a cer-
tified plug.
-Never wrap ground and/or torch cables around the operator's
body.
-Avoid to operate in humid or wet places without the proper pre-
cautions.
-Avoid to operate with the generator if machine protective panels
(sides and cover) have been removed in order to grant the safety
of both, the operator and the system.
4. ANTIFIRE EMERGENCY NORMATIVES
- Equip the workspace with proper fire extinguishers and periodi-
cally check the efficiency.
- Position on a solid and horizontal surface the generator, making
sure of the presence of a good aeration, do not obstruct the rear
panel, this will let the machine overheat.
- Follow all the regulations applicable when welding has to be car-
ried out on containers of lubricants or flammable substances.
5. MAIN LINE CONNECTIONS
Before connecting the system to the net, check that the input
voltage (V) and work frequency (Hz) correspond to the values that
are printed on the machine serial number sticker and make sure
that the main switch is on the "0" position.
The electrical connection to the net can be operated trough the
equipped cable as follows:
- yellow-green cable to earth;
- Remaining 3 cables to the 3 phases.
Connect to the input cable a certified plug with the correct capaci-
ty, predispose a net socket with safety fuses or with an automatic
safety switch OFF. Make sure that the earth cable is securely con-
nected to the earth conductor (YELLOW-GREEN) of the input net
line.
Note:
if input cable extensions are needed, make sure to use the
correct size, which does not have to be smaller then the one that
the machine is equipped with.
