5 GOUGING
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 welding current CA or constant wire feed CW,
see explanation in chapter 6.1 and 6.2.
