EWLa-1 (1.5% Lanthanated)

EWLa-1.5 designates a tungsten electrode
containing 1.3-1.5 wt-% 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 nonradioactive
substitutes for 2% thoriated tungsten as the
operating characteristics are very similar.
Lanthanated tungsten can be used for both
DC and AC applications.
