Machine display

The following welding parameters can be displayed before (nominal values), during (actual values) or
after welding (hold values):
Parameter
Welding current
Parameter times
Parameter currents
Frequency, balance
JOB number
Welding power
Welding voltage
When the hold values are displayed after welding and the settings are then changed (e.g. welding
current), the display will switch to the relevant nominal values.
 possible
 not possible
The parameters that can be set in the function sequence of the machine control depend on the selected
welding task. This means that if for example you have not selected a pulse variant, then you cannot set
any pulse times in the function sequence.
4.2.1

Setting the welding current (absolute/percentage)

The welding current for the ignition, secondary, end and hot start current can be set as a percentage of
the main current AMP or as an absolute value. To select, use the parameter
menu_ref_source_inline>Gerätekonfigurationsmenü</dg_ref_source_inline>.

Operating the machine control

4.3.1

Main screen

The machine control switches to the main screen after it has been turned on or a setting has been
completed. This means that the previously selected settings (indicated by signal lights where applicable)
and the nominal value for the current (A) are displayed in the left-hand welding data display. Depending
on the selection, the right-hand display shows the welding voltage (V) nominal value or the welding power
(kW) actual value. The control always switches back to the main screen after 4 sec..
4.3.2

Welding power setting

The welding power is set using the control button. You can also adjust the parameters in the operation
sequence or settings in the different machine menus.
