Huaye Ceriated Tungsten Electrode is a product of top quality adopting international standard helping inert gas to protect electric when welding and plasma cutting. Cerium oxide is used as additive so as to eliminate the radioactive contamination of Thoriated Tungsten Electrode and improve the circumstance of labor protection. The compressing strength of arc beam is narrower, more concentrated and more stable. The electric discharge power is 10% lower than that of Thoriated Tungsten Electrode. The permitted electric current is 5—8% higher than that of Thoriated Tungsten Electrode. Its wear is the lowest and its durability of cathode is the longest.
