Air carbon arc gouging
This method has also gone under the name of arc air gouging or carbon arc gouging. It
uses approximately the same equipment as for welding with coated electrodes. The
gouging electrode is a copper-plated carbon electrode, used in an electrode holder that
has an outlet for compressed air. The best power unit is one that can provide a high
current and, if possible, also a high short-circuit current, in order to maintain the correct
arc force. The electrode is held at an angle to the workpiece and, together with a jet of
compressed air, can remove metal at a high rate.
The carbon electrode should be connected to the positive pole of the power unit:
special electrodes are available for use with AC. Electrode diameters from 3 mm to
19mm are used, depending on the current available and the desired rate of metal removal.
