EWCe-2 (2% Ceriated) electrodes are tungsten
electrodes containing about 2% cerium
oxide, referred to as ceria. The EWCe-2 electrodes
were first introduced into the US market
in 1987. Several other grades of this type of
electrode are commercially practical, including
electrodes containing 1% ceria, but only
one grade, EWCe-2, has been incorporated
in this specification as having commercial significance.
The advantages of tungsten electrodes
containing ceria, compared to pure
tungsten, include increased ease of starting,
improved arc stability, and reduced rate of
vaporization or burn-off. Unlike thoria,
ceria is not a radioactive material.
These advantages increase with increased
ceria content. These electrodes operate
successfully with AC or DC, either polarity.
