By pressing the DATA CHANGE key, it is possible to change the
welding parameters not shown. The status bar is replaced by the
data setting line.
In the graph, the welding parameters
to be changed are clearly shown.
The entry line contains the name and numerical
value of the parameter to be modified. With the
T6 keys the parameter required is selected; set
new value and confirm it with the ENTER key. At
the end of the operation, the status bar will
appear again.
