Select the PROGRAMME of welding by pressing and releasing,
even several times if necessary, the PROGRAM SELECTION key
(T1) until the corresponding LED is lit and after that rotating the
ENCODER knob - V (E2) until obtaining on the PARAMETER DI-
SPLAY screen - V (D2) the number of the programme desired,
chosen on the basis of the type of electrode to use (basic, rutile,
Chrome-Nichel).

The SPECIAL FUNCTIONS “Fx” that are only available in the MMA
welding process are shown below. For all the other explanations
regarding this menu make reference to the relative paragraph.
■
FIRST LEVEL MENU
• HOT START (Hot) - At the start of the welding process it incre-
ases the current, adjustable in percentage, reducing in such a
way the risk of low function at the start of the connection.
• ARC FORCE (ArC) - During the welding process, it increases
the current in percentage, reducing in such a way the risk of fu-
sing the electrode to the piece.
Then there is an independent parameter, SPECIAL FUNCTIONS
MENU (SPC FnC) , that provides access to the SECOND LEVEL
MENU.

SECOND LEVEL MENU
See the “Special Functions Menu (SPC FnC)” paragraph.
4 - PRE-SETTING
Before welding it is possible to set the following parameters:
E1
T1
D1
WELDING CURRENT
Example: WELDING CURRENT
Press the PARAMETER SELECTION - A key (T1) until the LED
that corresponds to the WELDING CURRENT switches on. Turn
the ENCODER - A knob (E1) to change the value shown on the
PARAMETER DISPLAY - A screen (D1).
E2
T4
D2
ARC FORCE
WELDING VOLTAGE
HOT START
Example: ARC FORCE
Press the PARAMETER SELECTION - V key (T4) until the LED
that corresponds to the ARC FORCE switches on. Turn the EN-
CODER - V knob (E2) to change the value shown on the PARA-
METER DISPLAY - V screen (D2).
5 - WELDING
During the welding the display shows:
• PARAMETER DISPLAY screen - A (D1)
D1
WELDING CURRENT
- WELDING CURRENT ( ):the measured value of the current
of what is being welded.
• PARAMETER DISPLAY screen - V (D2)
D2
ARC FORCE
WELDING VOLTAGE
HOT START
- HOT START ( ): the value previously set.
- WELDING VOLTAGE ( ): the measured value of the voltage
- of what is being welded.
- ARC FORCE ( ): the value previously set.
