2% Ceriated Tungsten Electrodes ( WC20, Grey ) for TIG Welding

Ceriated Tungsten Electrode is a non -radioactive material. It 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 material.

The Brief Introduction of WC20 Grey Tungsten electrodes

Ceriated Tungsten Electrodes which contains a minimum of 97.30% tungsten and 1.80 to 2.20% cerium, was known as the first non-radioactive alternative to 2% thoriated tungsten electrode. It is especially excellent for DC welding with low amperage because it starts very easily at low amperages.

Application

    China Ceriated Tungsten Electrode is commonly used in welding orbital tube ,pipe and small or delicate parts. Like thorium, it is best used to weld carbon steel, stainless steels, nickel alloys and titanium, making it an obvious replacement for 2% thoriated tungsten electrode. 

    This tungsten electrode is used primarily for DC welding and may split if used for AC welding. 2% Ceriated tungsten electrode features slightly different electrical characteristics than thorium but most operators won't be able to tell the difference. Using 2% Ceriated tungsten electrode at higher amperages is not recommended. In these situations, the oxides will migrate quickly to the heat at the tip, removing the oxide content and nullifying its process benefits.
