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 param-
eters 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 3 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:
0 Basic
1 Rutile
2 Cellulose
3 Steel
4 Aluminium
5 Cast iron
Default 0
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 consuma-
bles 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 80%
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 current.
24
Minimum 0%, Maximum 500%, Default 30%
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 57.0V
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
7
Arc force cut-in threshold
Permits adjustment of the voltage value at which the
power source supplies the current increase typical of
the arc force.
Allows you to obtain different arc dynamics:
Low threshold: infrequent use of arc-force creates a
very stable but not very reactive arc (ideal for expert
welders and for easy-to-weld electrodes).
High threshold: frequent use of arc-force creates a
slightly more unstable but very reactive arc, able to
correct user errors or compensate for the electrode
characteristics (ideal for inexpert welders and for dif-
ficult-to-weld electrodes).
Parameter set in Volts (V).
Minimum 0.0V, Maximum 99.9V, Default 8.0V
40
Measurements
Permits selection of the type of measurement to be
shown on the display 4.
0 Real current
1 Real voltage
2 No measurement
Default 0
48
Buzzer volume
Adjustment of the buzzer volume.
Minimum Off, Maximum 10, Default 5
49
Contrast
Adjustment of the LCD display contrast.
Minimum Off, Maximum 15, Default 7
99
Reset
Allows you to re-set all the parameters to the default
values and restore the whole system to the conditions
predefined by Selco.
