CAC stands for which cutting process?

• A. Carbon arc cutting
• B. Copper arc cutting
• C. Carbon arc welding
• D. Calcium arc cutting

Answer: (A)

Carbon arc cutting is the process described by CAC. It uses a carbon electrode to form an electric arc that heats and melts the work metal, and a jet of air blows away the molten metal to create a cut. This is a cutting method, not a welding one, which is why terms like carbon arc welding would refer to a different process. Other options don’t fit because there isn’t a standard process called copper arc cutting or calcium arc cutting, and carbon arc welding describes welding, not cutting.
