What is the term used to describe the angle of the face when cutting?

The correct term used to describe the angle of the face when cutting is commonly referred to as the "work angle." This term is crucial in plasma arc cutting as it represents the angle at which the cutting torch is held relative to the workpiece surface. Achieving the appropriate work angle ensures efficient cutting and optimal quality of the cut edge.

A proper work angle helps in controlling the heat input and the intensity of the cut, which can affect the cut's cleanliness and the potential for dross formation. Implementing a correct work angle is therefore essential for achieving precise cuts and maintaining the integrity of the material being worked on.
