Radnor® 3/32" X 3" Ground Finish Lanthana Tungsten Electrode (10 Per Package)

Lanthanum Oxide Doped Tungsten Electrodes Containing 1.2% to 1.6% LA2O3 By Weight.

EWLa-1.5 designates a tungsten electrode containing 1.3%-1.7% by weight of dispersed lanthanum oxide (La2O3) for enhanced arc starting and stability, reduced tip erosion rate, and extended operating current range. These electrodes can be used as non-radioactive substitutes for 2% thoriated tungsten as the operating characteristics are very similar. Lanthanated tungsten can be used for both DCEN and AC applications.
