Air carbon arc gouging is a relatively inexpensive process for removing or cutting metal more rapidly than by grinding, flame gouging, or chipping. An arc is established between a carbon-graphite electrode and the workpiece; and the metal by the arc is blown away by a high-velocity air jet directed at the arc. The process can be used in a number of applications, including cutting or trimming parts to size, removing excess metal, and for cutting bevels for weld preparation. Unlike oxyfuel gas cutting, the new process can be used for most metals of engineering importance, incuding those that produce high-melting refractory lags. Stainless steel, cast iron, nickel, and copper alloys can be cut or gouged as easily as carbon steel. A detailed description of the process is given under the following headings: Equipment--cutting torch; carbon electrode, AC and DC plain and copper-coated; power sources for currents of up to 500 A; air supply at pressures from 40 to 80 psi with consumptions of 3 to 25 cfm. Techniques for Manual Gouging and Cutting, with notes on the different procedures for various base metals. Health Considerations, including precautions against excessive noise, burns, electric shock, arc radiation, and air contaminants. Among the conclusions, the Author points out that the air stream must have sufficient velocity and volume to clean the slag thoroughly from the kerf; and that trained operators are needed to produce high-quality results.
