The green undoped tungsten electrode was developed for welding with sinusoidal alternating current especially for light metals. It is not suitable for direct current welding. As the green pure tungsten electrode prevents the formation of a pure square wave due to its inertia and high work function, it is not recommended to use this welding electrode with inverter power sources. The ideal replacement for the green tungsten electrode is the E3®.
