WC20 cerium tungsten electrode is a non-radioactive tungsten electrode, and is known to be especially good for DC welding with low amperage because it starts very easily at low amps and usually requires about 10% less amps to operate than thoriated tungsten electrode. And is often used to replace thoriated tungsten electrode.

WC20 cerium tungsten electrode is very widely to be used for the welding of orbital tube, pipe, very small parts, short welding cycles and also where a specific number of welds are called and then the electrode is to be replaced. It performs well in DC welding and arc starting at low current settings, and offers excellent performance in AC processes.
Compared with pure tungsten electrode, cerium tungsten electrode has lower burning rate or evaporation rate. At low voltage, its life is longer than thoriated tungsten electrode. Cerium tungsten electrode is mainly used for direct current welding.
