5.2.1
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 chap. “TIG functional sequences”) 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 chap. “Conventional parameter setting in the functional sequence”).

5.2.2
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.
NOTE
The parameters for the ignition, secondary and end currents can be set and displayed as
percentage values (factory setting) or absolute values (see chapter “Switching between
percentage and absolute welding currents”).
