5.7.1

Synergic parameter setting in the functional sequence

When setting the welding current, all the necessary welding parameters are adjusted automatically during
the functional sequence > see 4.3.1 chapter with the exception of the gas pre-flow time. These welding
parameters can also be set in the conventional way if required (regardless of the welding
current) > see 5.11.4 chapter.
5.7.2

Conventional parameter setting in the functional sequence

All welding parameters in the functional sequence can also be adjusted, regardless of the welding current
set. This means that if the welding current is changed, the values for the down slope time or gas post-flow
time remain unchanged, for example. The welding task still needs to be selected as before using the
three basic parameters of tungsten electrode diameter, material type and seam type.
The parameters for the ignition, secondary and end currents can be set and displayed as
percentage values or absolute values > see 5.17 chapter.
5.7.2.1

Set the operating principle (conventional/synergic)

The settings are defined in the machine configuration menu > see 5.17 chapter.
