3.2 Front control panel
1 General alarm
Indicates the possible intervention of protection devices
such as the temperature protection.
2 Power on
Indicates the presence of voltage on the equipment
outlet connections.
3 Voltage Reduction Device
Shows that the no-load voltage of the equipment is
controlled.
4 7-segment display
Allows the general welding machine parameters to be
displayed during start-up, settings, current and voltage
readings, while welding, and encoding of the alarms.
5 Main adjustment handle
Allows adjustment of the selected parameter on graph 6.
The value is shown on display 4.
Allows entry to set up, the selection and the setting of
the welding parameters.
6 Welding parameters
The graph on the panel allows the selection and adjust-
ment of the welding parameters.
Welding current
Permits adjustment of the welding current.
Parameter set in Amps (A).
Minimum 3A, Maximum Imax, Default 100A
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 Off, Maximum 500%, Default 80%
Arc force
Allows adjustment of the Arc Force value in MMA welding.
Allows a plus or minus dynamic energy response during
welding, thereby facilitating the operations of the welder.
Parameter set as a percentage (%) of the welding current.
Minimum off, Maximum 500%, Default 30%
7 Welding process
Allows the selection of the welding procedure.
Electrode welding (MMA)
Basic
Rutile
Acid
Steel
Cast iron
Electrode welding (MMA)
Cellulose
Aluminium
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 guar-
anteed (weldability depends on the quality of the
consumables and their preservation, the operating and
welding conditions, the numerous possible applications,
etc.).
TIG LIFT welding
8 Measurements
Allows the real welding current or voltage to be dis-
played on 4.
Amperes
Volts
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 5 sec. (the cen-
tral zero on the 7-segment display confirms entry).
Selection and adjustment of the required parameter: by turn-
ing 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.
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 Off, Maximum 500%, Default 80%
7 Welding current
Permits adjustment of the welding current.
Parameter set in Amps (A).
Minimum 3A, Maximum Imax, Default 100A
