Pure Tungsten Electrodes - 99.95% W | Superior Arc Stability For Ac Welding, Exceptional Electrical Conductivity, Low Resistance

We are highly celebrated manufacturer, supplier and exporter of a range of Pure Tungsten Electrodes in Zhuzhou, Hunan, China. Pure tungsten electrode, also known as wolfram electrode, can be manufactured with black surface, polished surface or ground surface. It is normally marked with green. This kind of tungsten welding electrode is firstly used when welding argon arc. But under DC welding condition, the electrode can't prone to arc and may maintain unstable situation. In these circumstances, adding rare earth oxide can greatly improve the situation. Pure tungsten electrodes can work as welding electrode under ac condition or as resistance welding electrode. Pure tungsten electrodes (AWS classification EWP) contain 99.50% tungsten and are typically less expensive than "alloyed" counterparts.
