3.2 Front control panel
1 Power supply
Indicates that the equipment is connected to the mains
and is on.
2 General alarm
Indicates the possible intervention of protection devices
such as the temperature protection.
3 Power on
Indicates the presence of voltage on the equipment
outlet connections.
4 Overtemperature alarm
Indicates that the temperature protection device has
operated.
It is advisable not to switch off the equipment while the
alarm is on; the internal fan will thus keep operating
and will help to cool the overheated parts.
5 Torch hood protection alarm
Indicates any operation of the protection on the head
of the torch, which could be faulty or simply not prop-
erly screwed on.
6 Insufficient air pressure alarm
Indicates that the compressed air pressure is below 3.5
bar and therefore insufficient for correct operation.
7/8 Measurements
Allows the real cutting current or voltage to be dis-
played on 11.
Amperes
Volts
9 Air test button
Allows the compressed air circuit to be cleansed of
impurities and the carrying out of the appropriate pre-
liminary pressure and compressed air flow adjustments,
without power on.
10 Main adjustment handle
Allows the cutting current to be continuously adjusted.
11 7-segment display
Allows the general welding machine parameters to be
displayed during start-up, settings, current and voltage
readings, while cutting, and encoding of the alarms.

3.3 Set up
Permits set up and adjustment of a series of additional param-
eters for improved and more accurate control of the cutting
system.
Entry to set up: by pressing the encoder key for 5 sec.
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.
4 Cutting current

SERV: service
SELCO: Selco
751 Current reading
Allow the real value of the cutting current to be dis-
played.
752 Voltage reading
Allows the real value of the cutting voltage to be dis-
played.
