What is the function of an arc cutting gun?

The function of an arc cutting gun is primarily to transfer current to and guide a cutting electrode. This tool is specifically designed to facilitate the process of cutting metal using high temperature produced by an electric arc. When the arc is initiated between the cutting electrode and the workpiece, it generates sufficient heat to melt the metal at the point of contact. The design and features of the gun allow for precise control of the cutting process, ensuring effectiveness and efficiency.

The other options do not accurately describe the primary function of an arc cutting gun. For instance, measuring the temperature of the weld is not a direct role of the cutting gun; rather, that function would typically involve other instrumentation. Protection against fumes is important in welding environments, but it is more related to the use of personal protective equipment and ventilation systems than to the function of the cutting gun itself. Similarly, while automatic welding operations may involve the use of various tools, the arc cutting gun is specifically focused on cutting rather than assisting in those automated processes.
