TECHNICAL DAT A
Technical data relative to the performance of the machine
may be found on a plate (back panel) with the following
symbols, whose meaning is explained below.
1-
EUROPEAN Norm of reference, for safety and
construction of arc welding machines.
2-
Symbol for internal machine structure: inverter
transformer -rectifier.
3-
Symbol of planned welding procedure: welding with
continuous flow of welding wire.
4-
Symbol for power supply line: 3ph alternating voltage.
5-
Protection rating of casing: IP21 or IP22: it is protected
against solid foreign bodies of diam. 12.5mm (e.g.
fingers) and against drops of water falling vertically
(IP21) or with an inclination to the vertical of up to 15°
(IP22).
6 - Performance of welding circuit:
- U : maximum peak no-load voltage (welding circuit
0
open).
- I /U : current and corresponding normalised voltage
2

[U2 = (14+0,05 I ) V] that the machine can deliver during
2
welding.
- X: Duty cycle: indicates the time for which the machine
can deliver the corresponding current (same column).
Expressed in %,on the basis of a 10min cycle (e.g. 60%
= 6 minutes work, 4 minutes wait; and so on).
- A/V-A/V: Indicates the welding current adjustment
range (minimum - maximum) at the corresponding arc
voltage.
7-
Technical specifications for power supply line:
- U : Alternating voltage and power supply frequency of
1
machine (limit allowed ±15%):
- I
: Maximum current consumed by the line.
1max
- I : maximum effective current consumed

:
Value of delayed action fuses to be used to
protect the power line.
- Symbols referring to safety standards
9-
Manufacturer's serial number. Machine identification
(indispensable for technical assistance, requesting
spare parts, discovering product origin).
10- Symbol S: indicates that welding operations may be
carried out in environments with heightened risk of
electric shock (e.g. very close to large metallic
volumes).
Note: The plate example given shows the meaning
of the symbols and figures; the exact rating values
for the machine in your possession should be read
directly on the rating plate of the machine it self.
EARTH OF WELDING MACHINE (Table 1)
WARNING: none of the welding machines described in this
manual is equipped with a lifting device.
INSTALLATION
SITE
Locate the machine in an area where openings for cooling
air are not obstructed (forced circulation with fan); check that
conductive dusts, corrosive vapours, humidity etc., will not
enter machine.
POWER CONNECTION
Connection to the mains should be carried out using the
cable supplied.
The machines operate using single-phase.
The machine should be set up so that the voltage on the
plate corresponds to the mains voltage. Correct connection
Fig. A
Fig. B
is obtained by removing the side panel of the generator and
connecting the jumpers to the relevant terminal block
following the diagrams provided, (Fig.C).
PLUG: CONNECT TO THE MAINS CABLE A
STANDARDIZED PLUG OF ADEQUATE CAPACITY
( 3P+T) AND SET A MAINS SOCKET EQUIPPED WITH
FUSES OR AN AUTO MA TIC SWITCH.THE CORRECT
TERMINAL IS TO BE CONNECTED TO THE GROUND
CONDUCTOR (YELLOW-GREEN) OF THE MAINS
VOLTAGE SUPPLY (TAB.1).
WARNING
Failure to observe the above rules will make ineffective
the safety system installed by the manufacturer (Class
1) with resulting risks for persons (eg. electric shock)
and objects (eg. fires).
REPLACING THE POWER SUPPLY CABLE
THIS OPERATION MUST BE CARRIED OUT BY
SKILLED PERSONNEL!
OPTIONALS
- Electronic control box for pulse-welding
In addition to the adjustments and controls of the standard
electronic board, this board allows pulse-welding. The
welding and interval times can be set by two timers which
can be adjusted by means of two knobs which are marked
with appropriate symbols.
- Accessory for aluminium welding
Teflon wire guide hose for torch Ø 1-1.2 mm.
Roller for aluminium Ø 1.0-1.2 mm.
Contact tips for aluminium Ø 1.0 mm.
Contact tip for aluminium Ø 1.2. mm
Gas cylinder attachment
In order to achieve safe transportation, only one small or
medium-sized gas cylinder should be placed on the rear
support. Secure the gas cylinder by fastening chain, with
which it is wound, tightly to the hooks. Do not transport the
welder with large gas cylinders. Remove the cap from the
cylinder, clean the thread of the connection and open the
valve for a few seconds to let some of the gas escape. This
will prevent impurities from entering into the pressure
regulator and damaging it. Check that the connection of the
pressure regulator is fitted with a gasket and tighten it
securely. Connect the gas hose by tightening the metal hose
clamp well. Make sure that when the cylinder valve is open,
there are no gas leaks. The valve must be kept closed when
not using the welder to avoid wasting gas.
WIRE REEL ATTACHMENT (FIG. D-E )
- Open the side panel of the generator and remove the
locking screw and fit the wire reel onto the spindle so that
the end of the wire is facing upwards. Make sure that none
of the loops of wire on the reel are overlapping and that the
wire unwinds smoothly. Then re-tighten the screw.
- Make sure that the towing roller is suited to the wire used.
To replace this, simply remove the locking handwheel.
- Take the end of the wire and cut it, rounding off the point,
and thread it through the two wire guides; the wire should
not be bent and should be guided for a few centimetres,
making sure that it runs without implanting itself in the
guide hose of the torch.
- Make sure that the groove of the rollers is in line with the
wire guides.
- Adjust the lever of the pressure spring in order to provide
the towing rollers with sufficient pressure. Depending on
the wire used, the lever should be tightened accordingly;
excessive pressure could twist the wire and make wire
feeding irregular and if there is insufficient pressure, the
wire tends to slide on the roller.
- Adjust the brake with the knob on the spindle in order to
reduce the inertia of the wire reel without overloading the
