Characteristic : 2% Lanthanated Tungsten electrodes contains 2% Lanthanum oxide (LaO₃) that is also a non-radioactive material. It has good welding performance. Its electric conductivity is closed to that of the 2% thoriated Tungsten electrodes. Lanthanated electrodes operate at a slightly different arc voltage than Thoriated or Ceriated electrodes. Were developed around the same time as Ceriated Tungsten to help combat the increasing awareness of the radioactivity of Thoriated Tungsten.

Application : Generally used to weld carbon & stainless steels, nickel alloys and titanium.
