18/11/08 22262-GB
The engine driven welder is arranged as a single block composed of the engine and stainless steel box
structure where the front is the cover. All electrical components of the machine (except for the reactor
which is located on the base under the engine) are located inside, which are: an alternator with permanent
magnets, a high frequency chopper bridge, a control board for the welding current, an inverter which
generates alternating current of 50Hz with 230 or 110 volts and an electromagnet for the tick-over.
Main features:
•D.C. welding current 200A al 60%
•Continuous regulation of the welding current with "Chopper Technology"
•Suitable for basic and rutile electrodes. A reactance for cellulose electrodes is available as an option
•Antistick function (small arc force)
•Continuous auxiliary output 50Hz to 230V/3kVA to 110V/2kVA (50 Hz/60Hz)
•Engine accelerator at minimum/maximum at load take up
•Weight 57 Kg
•Acoustic Power 74 dBA to 7m
Electrical components of the machine:
•Permanent magnet alternator: the alternator has 2 galvanically separated windings, one for welding and
the other for the auxiliary output.
•Tick-over solenoid: an electromagnet in absence of load. When the load is present, welding or auxiliary
output, the electromagnet is not supplied any more and the engine speed goes to the maximum (4000
rpm rated open circuit).
•High frequency chopper diode bridge: it regulates the welding current using the “Chopper Technology”,
which chops the welding D.C. current at high frequency.
•Hall sensor: it measures with high precision the welding current and it’s completely isolated from the
welding circuit.
•Serie's reactance
•Welding current adjustment board: a board controls the welding process and supplies the engine acce-
lerator control electromagnet.
•Auxiliary in alternating current. An inverter generates alternating current 110/230V 50Hz with continuous
current (duty cycle 100%) of 1.8 kVA/ 2.5 kVA

user and under his direct responsibility to make a correct evaluation of the same risk and to adopt specific precautions (for
instance, adopting a I.P.D. -Individual Protection Device)
Acoustic Noise Level (LWA)- Measure Unit dB(A): it stands for acoustic noise released in a certain delay of time. This is not
submitted to the distance of measurement.
Acoustic Pressure (Lp) - Measure Unit dB(A): it measures the pressure originated by sound waves emission. Its value changes
in proportion to the distance of measurement.
The here below table shows examples of acoustic pressure (Lp) at different distances from a machine with Acoustic Noise Level
(LWA)of 95 dB(A)
Lp a 1 meter = 95 dB(A) - 8 dB(A) = 87 dB(A) Lp a 7 meters = 95 dB(A) - 25 dB(A) = 70 dB(A)
Lp a 4 meters = 95 dB(A) - 20 dB(A) = 75 dB(A) Lp a 10 meters = 95 dB(A) - 28 dB(A) = 67 dB(A)
PLEASE NOTE:the symbol when with acoustic noise values, indicates that the device respects noise emission limits
according to 2000/14/CE directive.

CONNECT WELDING CABLES
Insert the welding cable plugs completely in the
sockets, turning clockwise to lock them in place.
Connect the earth clamp to the negative pole
and the electrode holder to the positive.
☞Pay attention to the two polarities on the
welding circuit, which must not come into
electrical contact with each other.
- Carefully tighten the output cables to the
bushings; if loose, they can cause problems
of overheating and damage the bushings,
cables, etc.
- Make certain the grounding pincer is connec-
ted as near as possible to the work station.
ATTENTION
To reduce the risk of electromagnetic interfe-
rence, keep the welding cable length short and
keep them on or near the ground. If possible,
welding operations should not be done near
sensitive electronic devices. If interference
continues to occur, adopt additional measures:
shift the group, use shielded cables, line filters,
shield the entire work area.
If the above solutions do not suffice, consult
our Technical Servicing Department.
ADJUSTING THE WELDING CURRENT
The welding current is regulated by turning knob
“T” continuously. If set to the minimum (turned
fully in an anticlockwise direction) it provides
a current of approximately 30 A; if set to the
maximum (turned fully in a clockwise direction)
it gives a maximum current of approximately
200A.
RECOMMENDED ELECTRODES
All the electrodes on the market can be used.
