Zirconiated tungsten has good performance in AC welding, especially under high load current. Any other electrodes in terms of its excellent performance can not replace Zirconiated tungsten electrodes. The electrode retains a balled end when welding, which results in less tungsten permeation and good corrosion resistance. Our technical staffs have been engaged in research and testing work and succeeded in solving the conflicts between zirconium contents and processing properties. BTMMF is the only manufacturer that can produce this kind of electrodes.
