Which of the following is NOT a component of an oxyfuel cutting system?

The answer identifies an electric drill as not belonging to an oxyfuel cutting system. An oxyfuel cutting system typically consists of components specifically designed for the process of cutting metals using a flame generated by the combustion of a fuel gas, like acetylene, with oxygen.

Key components of this system include an oxygen cylinder, which supplies the oxygen needed to enhance the combustion of the fuel gas, and an acetylene cylinder, which stores the fuel gas used for the cutting process. The cutter tip is essential as it focuses the flame to achieve the high temperatures required for cutting through metal.

In contrast, an electric drill is not involved in this cutting process. An electric drill is a tool used to make holes in various materials or to drive screws, but it does not participate in the oxyfuel cutting method, which relies on the chemical reaction of oxygen and fuel gas rather than mechanical drilling or boring. Thus, in the context of oxyfuel cutting, the electric drill does not fit within the essential components of the system.
