Quick Access and Configuration Menu
for U0 User Interface
Users have access to the two menu levels:
Quick Access – basic menu related with welding
parameters settings
Configuration Menu – advanced menu associated with
machine configuration
parameters.
WARNING
Access to the menu is not available under welding, or if
there is a fault (status LED is not solid green).
Availability of the parameters in the Quick Access and
Configuration Menu depend on the selected welding
program / welding process.
After the device has been restarted the user settings are
restored.
Table 3 The default settings of basic menu

Parameter Selection Mode – the parameter name on the
left display [19] blinking.
Parameter Change Value Mode – the parameter value on
the right display [19] blinking.

Definition
Inductance – controls the arc characteristics when
short-arc welding. Increasing Inductance higher
than 0.0 provides a crisper arc (more spatter) while
decreasing the inductance less than 0.0 provides a
softer arc (less spatter).
Regulation range: from -10.0 to +10.0.
Factory default, Pinch is OFF.
Torch trigger mode (2-step / 4-step) - changes
the function of the torch trigger.
2 Step trigger operation turns welding on and off as
direct response to the trigger. Welding process
starts when the torch trigger is press.
4-Step mode allows to continue welding, when the
torch trigger is released. To stop welding, the
torch trigger should be pressed again.4-step
model facilitates to making long welds.
Run-in WFS – sets the wire feed speed from the
time the torch trigger is pressed until an arc is
established.
Regulation range: from minimum to maximum of
the wire feed speed.
Factory default, Run-in WFS is turned off.
Burnback Time – amount of time that the welding
is continue after the wire stops feeding. It prevents
the wire from sticking in the puddle and prepares
the end of the wire for the next arc start.
Burnback Time is set automatically (0,07s)
Regulation range: from 0s (OFF) to 0,25s
