Tungsten-Cerium/Lanthanum Electrodes are suitable for argon arc welding, plasma cutting electrodes and cathodes for high pressure spherical projection lamps and etc. Cerium (Lanthanum) in replacement of Thorium can eliminate the radioactive contamination of Tungsten-Thorium. Cerium (Lanthanum) electrodes are characteristic of easy arcing, stable arc flames, less ignitiono loss and deep molten pools.

Diameter (mm): 1.0~3.0, 3.0~6.5...
Length (mm): 100, 150, 200, 500...
Tolerance on dia. (mm): +/-2 (un-ground); +/-0.05 (ground)

Special requirement is welcome!
