Air arc gouging
5.4.6.1 Connection
Read and observe the documentation to all system and accessory components!
During gouging, an arc burns between a carbon electrode and the workpiece, heating the workpiece until
it is molten. At the same time, the molten metal is blown out with compressed air. Special electrode
holders with a compressed-air connection and carbon electrodes are required for gouging.
