CAC-A stands for which cutting process?

• A. Air carbon arc cutting
• B. Carbon arc cutting
• C. Air arc cutting
• D. Arc carbon cutting

Answer: (A)

CAC-A stands for Air Carbon Arc Cutting. In this process, a carbon electrode is used to create an electric arc with the workpiece, which melts a narrow path through the metal. A stream of compressed air is directed at the arc to blow away the molten metal and dross, enabling the cut to progress. This specific combination—air as the assist gas and a carbon electrode—distinguishes it from other phrasing. Using only carbon arc cutting would imply the arc without the air stream, which doesn’t provide the same cutting action. Using a term like air arc cutting or arc carbon cutting either omits the carbon electrode detail or isn’t a standard name for this process.
