Zirconiated tungsten is most commonly used for AC welding because it balls up well in AC welding and has a more stable arc than pure tungsten. As a result, they will take up too much of a welders costly time to produce an electrode that may not weld or weld for very long. For a given level of current, direct current with the electrode positive requires a much larger diameter, because the tip is not cooled by the evaporation of electrons but heated by their impact; and thus it will become hot and subject to erosion. However, it is a difficult manufacturing process to minimize the size of the grains while maximizing the consistency of the oxide distribution and maintaining the proper quantity of oxides. The EWLa-1 electrodes were developed around the same time as the Ceriated electrodes and for the same reason, that lanthanum is not radioactive. Note: It is difficult to compare different types of electrodes without testing because of the different properties of the oxides. Electrode grinders shape the ends of tungsten electrodes used in TIG (tungsten inert gas) welding tasks.
