7 Welding parameters
The graph on the panel allows the selection and adjust-
ment of the welding parameters.
Hot start
Allows adjustment of the hot start value in MMA.
Permits an adjustable hot start in the arc striking phases,
facilitating the start operations.
Parameter set as a percentage (%) of the welding cur-
rent.
Minimum 0% Maximum 500%, Default std 80%,
Default cls 150%
Welding current
Permits adjustment of the welding current.
Parameter set in Amps (A).
Minimum 3A, Maximum Imax, Default 100A
Arc force
Allows adjustment of the Arc force value in MMA.
Permits an adjustable energetic dynamic response in
welding, facilitating the welder's operations.
Parameter set as a percentage (%) of the welding cur-
rent.
Minimum 0%, Maximum 500%, Default std 30%,
Default cls 350%
8 Main adjustment handle
Allows the welding current to be continuously adjusted.
This current is unchanged during the welding if the
power supply and welding conditions vary within the
ranges indicated in the technical characteristics.
In MMA welding, the presence of HOT-START and
ARC-FORCE ensures that the average output current
can be higher than the one set.
Allows adjustment of the selected parameter on graph
7. The value is shown on display 4.
Allows entry to set up, the selection and the setting of
the welding parameters.

3.2.1 Set up

Permits set up and adjustment of a series of additional parameters
for improved and more accurate control of the welding system.
The parameters present at set up are organised in relation to the
welding process selected and have a numerical code.
Entry to set up: by pressing the encoder key for 5 sec. (the
central zero on the 7-segment display confirms entry).
Selection and adjustment of the required parameter: by
turning the encoder until displaying the numerical code relating
to that parameter. If the encoder key is pressed at this point,
the value set for the parameter selected can be displayed and
adjusted.
Exit from set up: to quit the "adjustment" section, press the
encoder again.
To exit the set up, go to parameter "O" (save and quit) and press
the encoder.

List of set up parameters
0 Save and quit
Allows you to save the changes and exit the set up.
1 Reset
Allows you to reset all the parameters to the default
values.
2 MMA Synergy
Allows you to set the best arc dynamics, selecting the
type of electrode used:
1 Standard (Basic/Rutile)
2 Cellulose
3 Steel
4 Aluminium
5 Cast iron
Default 1
Selecting the correct arc dynamics enables maximum
benefit to be derived from the power source to achieve
the best possible welding performances.
Perfect weldability of the electrode used is not guaran-
teed (weldability depends on the quality of the consum-
ables and their preservation, the operating and welding
conditions, the numerous possible applications, etc.).
3 Hot start
Allows adjustment of the hot start value in MMA.
Permits an adjustable hot start in the arc striking phases,
facilitating the start operations.
Parameter set as a percentage (%) of the welding current.
Minimum 0% Maximum 500%, Default std 80%,
Default 150%
4 Arc force
Allows adjustment of the Arc force value in MMA.
Permits an adjustable energetic dynamic response in
welding, facilitating the welder's operations.
Parameter set as a percentage (%) of the welding cur-
rent.
Minimum 0%, Maximum 500%, Default std 30%,
Default 350%
5 Arc detachment voltage
Allows you to set the voltage value at which the electric
arc switch-off is forced.
It permits improved management of the various operat-
ing conditions that occur. In the spot welding phase,
for example, a low arc detachment voltage reduces
re-striking of the arc when moving the electrode away
from the piece, reducing spatter, burning and oxidisa-
tion of the piece.
If using electrodes that require high voltages, you are
advised to set a high threshold to prevent arc extinction
during welding.
Never set an arc detachment voltage higher than
the no-load voltage of the power source.
Parameter set in Volts (V).
Minimum 0.0V, Maximum 99.9V, Default std 57.0V,
Default cls 70V
6 Antisticking enable
Permits enabling or disabling of the antisticking function.
The antisticking function permits reduction of the weld-
ing current to 0A in the event of a short circuit occurring
between the electrode and the piece, protecting the
gun, electrode and welder and guaranteeing safety in
the condition that has occurred.
0 Antisticking active
1 Antisticking not active
