Tungstens – 2% Ceriated
Ceriated Tungstens are a non-radioactive alternative to 2% Thoriated Tungsten.
It has excellent arc starting capabilities at low currents and therefore it has become the standard for many orbital tube and pipe welding equipment manufacturers.
Ceriated Tungstens take 10% less current to start and maintain a very stable arc
In addition, it is often used in other low amperage DC applications where small or delicate parts are being welded.
Generally not good for higher amperage applications, because the oxides migrate very quickly to the heat at the tip under these conditions and the oxide content and benefits are removed
