5 GOUGING
The process is available for certain machine types.
Main menu → Process
With arc air gouging, a special electrode comprising a carbon rod with a copper casing is
used.
An arc is formed between the carbon rod and the work piece, which melts the material. Air is
supplied so that the melted material is blown away.
When the GOUGING process is selected, you can choose between two control methods by
marking REGULATION TYPE using the positioning knob and pressing ENTER. Choose
between constant amperage CA or constant wire feed CW, see explanation in “CA, constant
amperage”, page25 and “CW, constant wire feed”, page25.
