BEFORE INSERTING THE MAINS PLUG, IN ORDER TO
AVOID THE FAIL OF POWER SOURCE, CHECK IF THE MAINS
CORRESPONDS TO THE WISHED MAIN SUPPLY.
CAUTION:
- Before making any electrical connections, check that
the machine's rated data correspond to the mains volt-
age and frequency available at the place of installation.
- The machine must be supplied by three conductors,
plus a fourth separate conductor used specifically for
connecting to protective earth (PE); it can therefore be
connected solely to three-phase distribution systems.
- Depending on the mains voltage available, set the volt-
age switch using the interlock screw (see figure).
- Connect the power cable to a standardized plug (3p +
E) of adequate capacity, fitted with an earth terminal to
which the yellow-green cable conductor will be connect-
ed.
- Prepare a standardized mains socket equipped with
fuses or a circuit breaker of adequate capacity; the spe-
cific terminal must be connected to the earth network of
the distribution network (when sizing the supply line, ca-
pacity and power, refer to the data given on the genera-
tor's data plate).
CAUTION: FAILURE TO OBSERVE THE ABOVE RULES
MAKES THE MANUFACTURER'S SAFETY SYSTEM (CLASS I)
INEFFECTIVE, WHICH COULD CREATE SEVERE HAZARDS
FOR PEOPLE (E.G., ELECTRIC SHOCK) AND PROPERTY
(E.G., FIRE).

HANDLING AND TRANSPORTING THE GENERATOR
OPERATOR PROTECTION: HELMET - GLOVES - SAFETY
SHOES.
THE WELDING MACHINE WEIGHS MORE THAN 25 KG AND
IT MUST NOT BE LIFTED BY THE OPERATOR. READ THE
FOLLOWING PRECAUTIONS CAREFULLY.
The welding machine is easy to lift and transport. Transporting the
equipment is easy but must be done respecting the following rules:
1.
Always disconnect the generator and all the accessories
from the mains supply before lifting or handling operations.
2.
Do not lift, drag or pull the equipment by the welding or power
cables.
3.
To lift this machine, pass an appropriate nylon belt under-
neath it or use the specific eyebolts provided.
2.3
POSITIONING THE WELDING MACHINE
SPECIAL INSTALLATION MAY BE REQUIRED WHERE
THERE IS OIL OR COMBUSTIBLE FLUIDS OR GASES. CON-
TACT THE COMPETENT AUTHORITIES.
When positioning the welding machine, ensure that the following
precautions are observed:
1.
The operator must have unobstructed access to controls and
equipment connections.
2.
Check that the power cable and fuse of the socket for welding
machine connection are adequate for the current required by
the machine.
3.
Do not position the welding machine in confined places. Ven-
tilation of the welding machine is extremely important. Al-
ways make sure that the ventilation slots are not obstructed
and there is no danger of obstruction during welding. Addi-
tionally, always avoid very dusty or dirty places where dust or

other objects can get drawn in by the welding machine, caus-
ing it to overheat and get damaged.
4.
The welding machine, including the welding and power ca-
bles, must not obstruct passageways or the work of others
5.
Always position the welding machine securely to avoid falling
or overturning.
6.
When the welding machine is located in a raised position,
there is the risk it might fall.

CONNECTION AND PREPARATION OF EQUIPMENT
FOR COATED ELECTRODE WELDING.
SWITCH OFF THE WELDING MACHINE BEFORE CARRYING
OUT THE CONNECTIONS.
CONNECT THE WELDING ACCESSORIES CAREFULLY IN
ORDER TO AVOID POWER LOSSES.
1.
CLAMP cable (electrode holder):
to the POSITIVE (+) terminal (see "WELDING" paragraph).
2.
EARTH return cable:
to the NEGATIVE (-) terminal (see "WELDING" paragraph).
CAUTION:
1.
Tighten the terminals carefully so that the ends of the
welding cables are secured; otherwise, the terminals
would overheat and quickly deteriorate, making the gen-
erator less efficient.
2.
Use the shortest possible clamp and earth leads (_ 10
m.); where it is absolutely necessary to increase the dis-
tance between the generator and the place of work, use
cables of cross-section immediately greater than the
normal recommendation for every 10 metre increase in
length (e.g., pass from 25 mm2 to 35 mm2). Do not use
welding cables longer than 30 metres.
3.
Using metal structures that are not part of the workpiece,
such as the welding current return conductor, can be
dangerous and produce unsatisfactory welding results.

WELDING
Almost all coated electrodes must be connected to the generator's
positive pole (+); exceptionally to the negative pole (-) (acid coating).
The welding current must be adjusted according to the diameter
of the electrode used and the type of joint you want to make; by
way of example, the currents that can be used for the various elec-
trode diameters are:
Ø electrode (mm)
1,6
2
2,5
3,2

It is anyhow always essential to refer to the instructions given on
the package of electrodes used. Bear in mind that for the same
electrode diameter, high currents will be used for horizontal weld-
ing and low currents must be used for vertical or overhead weld-
ing. The mechanical characteristics of the welded joint are
determined, not only by the current, but also by welding parame-
ters such as the diameter and quality of the electrode, length of
the arc, speed of execution and also the conservation of the elec-
trodes that must be kept sheltered from moisture protected in spe-
cial packages or containers.
