In oxyacetylene welding, which gas is primarily used for cutting?

Acetylene
Argon
Helium
Oxygen

The correct answer is: Oxygen

Oxyacetylene welding is a process that involves combining oxygen and acetylene gases in a high-heat flame to cut and weld metals. While acetylene is used for the heating component in this process, it is oxygen that primarily serves as the cutting gas. Argon and helium are often used as protective gases in welding, but they do not have the same cutting capabilities as oxygen. Therefore, oxygen is the most appropriate gas choice for cutting in oxyacetylene welding.
