A gouging electrode is a metal fabrication tool used in arc gouging processes. It is a specialized welding gouge that can be used to cut, shape, and remove metal from a workpiece. The electrode is made of copper or other metals and has an insulated handle that allows the user to control the arc. The electrode is connected to an electric current source and when it comes into contact with the workpiece, it creates an arc that melts the metal and removes it from the surface. This process can be used for cutting, shaping, or removing metal from any type of workpiece.
