____ cutting uses a stiff, highly ionized, extremely hot column of gas to almost instantly vaporize the metal being cut.
A) Laser beam
B) Air carbon arc
C) Oxyfuel gas
D) Plasma arc

Question

Quizplus · Accepted Answer

Plasma arc cutting uses a highly ionized gas (plasma) to create a high-temperature cutting area that can quickly vaporize metal. The other options utilize different methods such as a focused beam of light (laser), an electric arc between a carbon electrode and the metal (air carbon arc), or a flame produced by the reaction between oxygen and a fuel gas (oxyfuel gas).
