- That component in an arc welding circuit through which electric current is conducted between the electrode holder and the arc itself.
- In resistance welding, that component through which the electric current in the welding machine passes directly to the work and that is usually accompanied by pressure, such as from a clamp.
- A conductor which serves to deliver, receive, collect, emit, deflect, or control electric charge carriers. An electrode provides the path for current entering or leaving a medium such as a dielectric, electrolytic solution, semiconductor, gas, or vacuum. In an electron tube or electrolytic cell, for instance, the anode is the positive electrode, while the cathode is the negative electrode. It is often a metal, and may consist, for instance, of a wire, grid, plate, or region.
