Cerium-Tungsten Electrodes have good starting arc performance under the condition of low crrrent. The arc current is low, therefore the electrodes can be used for welding of pipe,stainless and fine parts. Cerium-Tungsten is the first choice for replacing Thoriated Tungsten under the condition of low DC.BTMMF has several patents for WC electrodes' production.
