PAC is the acronym for which cutting process?

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

Answer: (A)

Plasma arc cutting is what PAC stands for. This process uses an electrical arc to ionize a gas into plasma, creating a high-temperature jet that melts the metal and blows the molten metal away to form a cut. The plasma torch concentrates this heat and is usually helped by a separate gas stream to sustain and direct the plasma, enabling fast, accurate cuts on many conductive metals across a range of thicknesses. It also works well through coatings and paints because the plasma jet melts through the surface. The other terms describe different methods: carbon arc cutting relies on a carbon electrode and isn’t a true plasma jet cutting method, air carbon arc cutting uses air with a carbon electrode for gouging rather than cutting with a plasma jet, and shielded metal arc cutting isn’t a recognized cutting process in practice.
