SELECTION LED

■ VRD LED

The Voltage Reduction Device (VRD) is a safety device that re­duces voltage. It prevents voltages forming on the output termi­nals that may pose a danger to people.
Two-tone LED (off - red - green) indicates enabling of the VRD. In
the welding process:

• MIG MAG (Synergic and Manual) / JOB: the VRD device is not

managed and therefore the LED always will be off.
MMA: the operator can decide whether or not to activate the

•

VRD device (to activate the VRD device see the corresponding
paragraph) based on its necessities and therefore the LED will
be lit and will indicate the activation of the device.
TIG Lift: the VRD device is always inserted, independently from

•

the state of the JUMPER and therefore the LED always will be lit.

■ WELDING MODE SELECTION LED

When one or a combination of these LED is lit, it means that the
corresponding manner of welding has been selected.

Switching on the welding
machine and initial screen

At the switching on of the welder (press the switch, located on the
back panel, at the position I), the control performs a short operation
of MACHINE CHECK (all of the LED light themselves simultane­ously so as to verify their actual operation), and the panel display
the INITIAL SCREEN (see the demonstrative figure), after which
the operator can begin to work.

▪ PARAMETER DISPLAY screen - V▪ PARAMETER DISPLAY screen - A

■ PARAMETER SELECTION LED - A

When one of these LEDs is on it means that the corresponding
welding parameter has been selected.

■ PROGRAMME SELECTION LED

This LED will be lit only when the operator selects a welding pro­cess (in which there welding programmes present) and the rela­tive associated programme.

■ PARAMETER DISPLAY screen - A

This Display shows the values / numbers (set or measured) of the
following parameters (if active):

• THICKNESS OF WELDED ITEM (

• WELDING CURRENT (

• WIRE SPEED (

).

• WELDING PROGRAM (

).

).

).

■ HOLD FUNCTION LED

Flashing, it indicates that the values of the parameters views on
the PARAMETER DISPLAY - A and V are respectively the values
that are set or measured at the conclusion of the last welding. The
LED flashes for 15 seconds consecutively before turning itself off or
until the moment that the operator varies any parameter by means
of the use of the handles.

■ WELDING PROCESS SELECTION LED

When one of these LEDs is on it means that the corresponding
welding process has been selected.

■ PARAMETER SELECTION LED - V

When one of these LEDs is on it means that the corresponding
welding parameter has been selected.

■ PARAMETER DISPLAY screen - V

This Display shows the values / numbers (set or measured) of the
following parameters (if active):

• ARC LENGTH ADJUSTMENT (

• WELDING VOLTAGE (

).

• ELECTRONIC INDUCTANCE (

).

).

■ JOB SAVING MEM LED

Flashes while saving a JOB.

■ Fx LED - SPECIAL FUNCTIONS

Switched on when special Fx parameters are displayed.

Viewing the software version installed

1) When the welding machine is working hold down the WELD-

ING PROCESS SELECTION key (T2) and WELDING MODE
SELECTION key (T3) together for about 2 consecutive sec­onds.

T2 T3

2) On both displays appears a running string that indicates the

VERSION OF THE SOFTWARE installed on the welder.
The rotation of one of the two ENCODER Knobs - A (E1) or
V (E2) by the operator during the display of the string version
software provokes the block (for 1 second), on both the dis­plays, of the movement of the string itself.

E2E1

3) Ending viewing of the software version on the control panel
can come about in 2 different ways:

• Automatically: by waiting for the display time to elapse.

• Manually: by pushing any key.

Loading of the wire

In the MIG-MAG-PULSE-DOUBLE PULSE welding processes,
with the welder in operation, it is possible to load the wire inside
the torch, following this simple procedure:

• Keep the torch button held down.

• After a time of about 2 seconds, the wire begins to load itself at

a constant speed.
This operation is also indicated by a message made up of a nu-

•

merical value for the wire speed, followed by “LoAd” (see figure).

•

Rotate the ENCODER - A (E1) knob to change the wire load­ing speed.

• To finish the loading of the wire release the torch button.

WARNING: Changes to values are immediately activated (no fur­ther confirmation is required and they will be displayed immedi­ately) or, at least they will become active the next time welding is
done. The operator can edit the functions (not the wire speed and
other parameters) when welding is underway and continue weld­ing without having to exit the SPECIAL FUNCTIONS “Fx” menu.

The special functions allow the operator to regulate further param­eters, operations and do partial resetting, and are operative, in a
different way, within each welding process.
Table 1 shows the special functions available. Details of the mean­ing of the columns are as follows:

• FUNCTION column: name of the special function.

DISPLAY column: symbol for the special function (message

•

shown in the PARAMETERS DISPLAY - A screen).
FACTORY column: Factory setting for the special function (mes-

•

sage shown in the PARAMETERS DISPLAY - V screen).

• RANGE column: regulation field for the special function.

The last two groups of columns, WELDING PROCESS and

•

MIG-MAG WELDING MODE indicate the welding process and
mode in which the special function can be selected. Example:
the SPOT WELD TIME function can be selected only when one
is welding in synergistic MIG-MAG-PULSE or manual SPOT
2T mode.

To carry out the reset of the settings / parameters, proceed in
the following manner:

• Rotate the ENCODER - A (E1) knob until both the displays

7 - ACTIVATING THE VRD DEVICE

The Voltage Reduction Device (VRD) is a safety device that reduc­es voltage. It prevents voltages forming on the output terminals that
may pose a danger to people. The factory settings do NOT set out
an active welding device during electrode welding.
If the operator wishes to weld in MMA using the VRD device (which
must be done with the welding machine switched off), they must:

1) Use a suitable screwdriver to unscrew the 4 screws that fix
the control panel to the welding machine.

2) Remove the “VRD” JUMPER on the DIGITAL INTERFACE
PCB (Fig. B).

3) Use a suitable screwdriver to tighten the 4 screws that fix the
control panel to the welding machine.

4) Start the welder by pressing the switch, located on the back
panel, at the position I.

After switching on, but with the machine at rest, the control panel
will show the VRD LED on in the colour GREEN and this means
that the device is active.
During the welding phase, this LED becomes RED, which however
does not indicate a malfunctioning of the welder but the fact that
the VRD device is in function and, at the conclusion of the welding
operation, the tension will be reduced within a maximum greatest
time of 0.3 seconds.

JOB

1 - CREATING AND SAVING A JOB

This operation makes it possible to create and save welding set­tings (points) that can be called up by the operator at any time.
The control panel provides the possibility of saving a total of 99
JOBS spread over all the welding processes. There are not lim­its to the quantity or position of the points that can be saved for
each process!
When it leaves the factory the welding machine does not have
any JOBS saved in it and so the operator will find the control pan­el in this condition:

Having defined the parameters the operator needs to do their work
correctly, they can be saved by creating an AUTOMATIC WELD­ING POINT (JOB), proceeding as follows:

1) Hold the SAVE “MEM” key (T2) down for at least 2 consec­utive seconds until both displays show the flashing wording
that represent the first AUTOMATIC WELDING POINT (JOB)
free and/or available to the operator that can be used for sav­ing the data (e.g.: A01).

T2

To be able to choose another automatic welding point (JOB)

that is free for saving the data, simply turn one of the two EN­CODER (E1-E2) knobs until you reach the required point.

2) Hold down the SAVE “MEM” (T2) Key down for at least 2 con­secutive seconds to save JOB and automatically load the set­tings / parameters (including special functions) for the JOB just
saved.

3) To exit the JOB, press and release the WELDING PROCESS
SELECTION key (T2).

the operator can see and verify the settings, previously saved
and memorised, pressing and releasing the PARAMETER SE­LECTION key - A (T1) or in alternative the PARAMETER SELEC­TION key - V (T4).
The SPECIAL FUNCTIONS “Fx” Key (T3) contained within each
individual JOB can be viewed (but not modified) by simply keep­ing the SPECIAL FUNCTIONS “Fx” key (T3) pressed for a dura­tion of about 2 seconds.
The display of the parameters (special functions included) lasts
only a few seconds, then the panel shows, in an automatic way,
the previous working condition.

6 - MODIFICATION AND OVERWRITING OF A
MEMORISED JOB

To edit and overwrite a JOB proceed as follows:

1) Select JOB, pressing and releasing, even various times if nec­essary, the WELDING PROCESS SELECTION key (T2) until
the corresponding LED lights up.

2) Select the individual JOB to modify and overwrite rotating the
ENCODER knob - V (E2).

3) Bring up and activate the JOB, loading its settings in the weld­ing process it comes from, keeping the SAVE “MEM” key (T2)
pressed for a duration of about 2 seconds.

4) Acquire the parameters necessary for editing the JOB.

5) Hold the SAVE “MEM” key (T2) down for at least 2 consec­utive seconds until both displays show the flashing wording
that represent the first AUTOMATIC WELDING POINT (JOB)
free and/or available to the operator that can be used for sav­ing the data.

6) Rotate the ENCODER knob - V (E2) until identifying the indi­vidual JOB that will be overwritten.

7) Keep pressed, for at least 3 consecutive seconds, the SAVE
“MEM” key (T2) to confirm and make the operation effective.

FILE SYSTEM ERROR

NON automatic reset error.
Immediately contact technical
assistance dept.

STICKING
This error is displayed when a
shortcircuit has been formed
between the machine’s output
terminals for more than 1.2 seconds.

NON automatic reset error.

To remove the error state, eliminate
the short circuit so that the voltage
on the torch goes above the
threshold value again. At this stage
the error condition disappears and
the welding machine goes back to
the mode prior to the sticking. If the
torch trigger is still pushed, it must be
released and pressed again to begin
welding again.

AUT ADJ

The table includes 2 types of errors:

• Automatic reset error: Once the alarm condition has been re-

solved the welding machine starts working again and the oper­ator can weld again!
NON automatic reset error: To remove the alarm status and

•
reinstate correct operation of the machine, the welding equip­ment must be switched off.
The machine will then be working again and the operator can
weld again!

PLEASE NOTE: If, when switching on, the error status pre­sents itself again, immediately contact the Technical Assis­tance Department.

This is necessary so that our technical assistance dept (that must
be contacted each time the error messages appear on the
welding machine’s operator interface) is able to resolve the

problems more easily and as quickly as possible, thanks to the re
ports by the user, and also because, in the meantime the welding
machine does not allow the operator to do their work.

POWER LIMITATION
This alarm appears if the power limit
is exceeded. The alarm alternates
with the standard display every 1.5
seconds, despite which the machine
continues to weld, supplying limited
power, but complying with the values
shown on the data plate.
