CAC-A is the acronym for which cutting process?

• A. Air carbon arc cutting
• B. Carbon arc cutting
• C. Plasma arc cutting
• D. Shielded metal arc cutting

Answer: (A)

Air Carbon Arc Cutting is the process referred to by that acronym. In this method, an electric arc is struck between a carbon electrode and the workpiece, melting the metal. A directed stream of air is then blown through the nozzle to blast away the molten metal, creating the cut. The name comes from using air as the cutting gas along with a carbon electrode. This is distinct from plasma arc cutting, which uses a plasma gas to form a plasma jet, and from shielded metal arc cutting, which isn’t a standard cutting process. So the acronym CAC-A specifically points to Air Carbon Arc Cutting.
