WZr(Zirconium-Tungsten Electrode)

Zirconium-Tungsten Electrode bears a fine performance in welding under the condition of AC and has a good anti-corrosiveness,Especially in the case of high load of current,the Zirconium-tungsten excellent performance is far better than that of other electrodes,When welding,the end of zirconium-Tungsten Electrode remains pellet-shaped,Which can reduce the possibility of tungsten oozing.It is suitable for welding magnesium,aluminum and their alloy under alternating current.
