铈钨电极在低电流条件下有着优良的起弧性能，维弧电流较小。因此， 它常用于管道，不锈钢制品和细小精密部件的焊接。在低电流直流条件下，铈钨电极是钍钨电极的首选替代品。
Cerium-Tungsten Electrode has good starting arc performance under the condition of low electric current. The arc current is low, therefore the electrodes can be used for welding of pipe, stainless and fine parts. Cerium-Tungsten electrode is the first choice for replacing thoriated tungsten electrode under the condition of low DC.
