The specific characteristics of this welding machine (INVERTER), such as high speed
and adjustment precision, give excellent welding quality.
Adjusting with the "inverter" system at power supply input (primary) drastically reduces
the volume of both the transformer and the levelling reactance, leading to a welding
machine that is small and not bulky, and which is therefore easier to handle and move.

the corresponding current (same column). It is expressed as %, based on a 10
minutes cycle (e.g. 60% = 6 minutes working, 4 minutes pause, and so on).

11- Symbols referring to safety regulations, whose meaning is given in chapter 1
"General safety considerations for arc welding".
Note: The data plate shown above is an example to give the meaning of the symbols
and numbers; the exact values of technical data for the welding machine in your
possession must be checked directly on the data plate of the welding machine itself.

4. DESCRIPTION OF THE WELDING MACHINE

4.1 BLOCK DIAGRAM

The welding machine consists basically of power and control modules made on PCB's
and optimised to achieve perfect reliability and reduced maintenance.
This welding machine is controlled by a microprocessor that allows a large number
of parameter settings so as to achieve perfect welding in any condition and with any
material. However, to make the best use of its properties it is necessary to be fully
aware of its possibilities.
Description of the welding machine (FIG. B1)
1- Three-phase power supply input, rectifier unit, and levelling capacitors.
2- Transistors (IGBT) switching bridge and drivers, it commutes the rectified power
supply voltage to high frequency alternating voltage and adjusts the power
according to the required welding current/voltage.
3- High frequency transformer; the primary winding is powered by the voltage
converted by block 2; it adapts voltage and current to the values required for arc
welding and at the same time galvanically insulates the welding circuit from the
power line.
4- Secondary rectifying bridge with levelling inductance; it switches the alternate
voltage / current supplied by the secondary winding into current / voltage with an
extremely low wave.
5- Control and adjustment electronics; instantly check the value of the welding
current and compare it with the value set by the operator; modulate the control
impulses of the IGBT adjustment drivers; supervise the safety systems.
6- Panel for setting and seeing the parameters and operation modes.
7- Welding machine cooling fan.
8- Remote adjustment.
9- Wire feeder.
Description of the wire feeder (FIG. B2)
1- Generator.
2- Control and adjustment electronics; instantly check the motor speed and compare
it with the value set by the operator.
3- Panel for setting the parameters and operation modes.
4- Wire feeder unit.
4.2 CONTROL, ADJUSTMENT AND CONNECTING DEVICES
4.2.1 Rear panel (FIG. C)
1- Power cable (3P + T (Three-phase)).
2- Main switch O/OFF - I/ON.
3- Connector for remote control:
Three different types of remote control can be connected to the welding machine
using the relative 14-pole connector at the back. Each device is recognised
automatically and can be used to adjust these parameters:
- Remote control with one potentiometer:
In the MMA, TIG LIFT and GOUGING mode, rotating the potentiometer knob
varies the welding current. In the MIG mode, rotating the potentiometer knob
varies the welding voltage. Adjustments can only be made with the remote
control.
- Pedal remote control:
In the MMA, TIG LIFT and GOUGING mode, the value of the current is
determined by the position of the pedal. In the MIG mode the pedal remote
control is ignored.
- Remote control with two potentiometers:
1st Potentiometer: In the MMA, TIG LIFT and GOUGING mode, it adjusts the
welding current while in the MIG mode it adjusts the welding voltage.
2nd Potentiometer: In the MMA mode, this potentiometer adjusts the ARC
FORCE, while in the MIG, TIG LIFT and GOUGING mode it is ignored.
Rotating a potentiometer displays the parameter being varied (which can no
longer be controlled using the panel knob).
4.2.2 Front panel FIG. D
1- Positive (+) fast coupling for connecting the welding cable.
2- Negative (-) fast coupling for connecting the welding cable.
3- Connector for connecting the wire feeder.
4- Control panel.
5- Remote control selection push-button.
REMOTE CONTROL
Used to transfer control of the welding parameters to the remote control.
6- Welding mode selection push-button.
MMA - MIG - TIG LIFT - GOUGING
MIG
GOUGING
Operation mode: welding with coated electrode (MMA), wire welding (MIG), TIG
welding with arc strike upon contact (TIG LIFT), and gouging.
7- Push-button for selecting the parameters to be set.
The push-button selects the parameter to be adjusted using the Encoder knob (8);
the value and unit of measurement are shown respectively by the display (10) and
LEDs (9a).
N.B.: The parameters can be set as desired by the operator. There are, however,
value combinations that do not have a practical meaning for welding; in this case
the welding machine may not operate correctly.
N.B.: RESETTING ALL THE FACTORY SETTINGS (RESET)
Press the push-button (7) to reset all the welding parameters to their default value.
7a HOT START
In the MMA mode, this is the initial "HOT START" overcurrent (adjustment
0÷100); the display shows the percentage increase as to the value of the
selected welding current. This adjustment improves starting.
7b MAIN CURRENT (I )
2
I
2
In the MMA, TIG LIFT and GOUGING modes it represents the welding current
measured in Amperes. In the MIG mode it represents the welding voltage.
7c ARC-FORCE or ELECTRIC REACTANCE
In the MMA mode, this is the dynamic "ARC-FORCE" overcurrent (adjustment
0-100%); the display shows the percentage increase as to the value of the
pre-selected welding current. This adjustment improves welding fluidity,
prevents the electrode from adhering to the workpiece and makes it possible
to use different types of electrode. In the MIG mode it represents the electronic
reactance (adjustment 1-10%). This adjustment determines the dynamics of
the current during welding. The higher the value is set the faster the current
varies to face the impedance variations at output. Setting the correct value
greatly depends on the type of wire and material used, and gives fluid and
regular welding in every situation.
7d VOLTAGE REDUCTION DEVICE (VRD)
VRD
MMA
In the MMA mode it enables or disables the device that reduces the loadless
output voltage (regulate at YES or NO). With the VRD enabled, operator
safety increases when the welding machine is on but not in the welding mode.
8- Encoder knob for setting the welding parameters, selectable with key (7).
