The performance of Zirconiated tungsten electrodes

     Zirconiated tungsten electrode is in order to improve the pure tungsten electrode welding under the condition of high load melting workpiece and electrode pollution shortcomings development varieties, the most obvious feature of the electrode is in the case of high load current, tungsten electrodes into a ball, to keep the lower permeability, and it has good corrosion resistance.

Tungsten zirconium electrode, like pure tungsten electrode, can only be welded in ac environment.The tungsten zirconium electrode has good welding performance in ac environment.Especially in the case of high load current, the excellent performance of tungsten zirconium electrode is not replaceable by other electrode.

It is an ideal method of ac welding and has high resistance to pollution.Its current carrying capacity is equal to or greater than the tungsten electrode.

Dc welding is not recommended under any circumstances.
