What is the function of a plasma cutter?

A plasma cutter serves the specific function of cutting through conductive metals. It utilizes a focused beam of plasma—an electrically charged gas—to create a high-temperature arc that melts and effectively removes material as it moves through the metal being cut. This process is suitable for various conductive materials like steel, aluminum, and copper.

Welding, grinding, and drilling are distinct processes that have different equipment and techniques. Welding involves joining materials together, which plasma cutting does not accomplish. Grinding typically refers to smoothing or reshaping surfaces rather than cutting through materials. Drilling is a method used to create holes and is performed with drill bits, which is not the function of a plasma cutter. The unique capability of the plasma cutter to make precise cuts in conductive metals is what defines its primary function.
