Our company is the earliest manufacturer of cerium tungsten electrodes, and our products have obtained the provincial science and technology progress prize. Ceriated tungstenelectrodecontains 18%-22%ceria, electron work function is 2. 4eV, and plays a good performance on starting arc and stabilizing arc at low current. Therefore, cerated tungsten electrode are commonly used in pipeline, stainless steel and small precision parts welding It's the first choice in the low current and diameter below 2.0mm.

The high-mobility cerium oxide is not suitable for the application in the high current. If it's used in the high current, the oxide may accelerate to the high hot area, the top of the tungsten electrode, which damages the uniformity of oxide. the benefit brought by ceriiim oxide will disappear.
