The arc generation and stability is similar as thoriated tungsten electrode. There is no radioactive pollution and its chemical stability is good, so ceriated tungsten eletrodes are environment friendly products. It is very esay to generate arc and keep arc stable with low current. So this tungsten electrode is very popular with low current welding, especially used for pipe and small article welding, internittent welding, and quantitative welding. This tungsten electrode is not suitable for high current welding. Because under this situation, the oxide transders to the high temperature area: the electrode top of welding. The equitability of the oxide will be destroyed and the above advantages because of the oxide equitability.
