The multi-composite Rare-earth Tungsten Electrode is the tungsten material with some kinds of rare earth oxides.  Each additive works to benefit of others and serve as a complement at the same time. In comparison to thoriated electrodes this electrode is less harmful to the environment and not radioactive. The electrodes offer excellent ignition characteristics and consistent welding properties. They are universal and suitable for all applications in the whole range of DC and AC welding for non-alloyed and high-alloyed steel, aluminum, titanium, nickel, copper and magnesium alloys. Because of their great ignition properties they are also suitable for automated welding. Due to the low electrode temperature, they offer an increased current carrying capacity and longer service life than thoriated electrodes.


Rare-earth tungsten electrodes (AWS classification EWG) contain unspecified additives of rare-earth oxides or hybrid combinations of different oxides, but tunsgten electrodes manufacturers are required to identify each additive and its percentage on the package. Depending on the additives, desired results can include a stable arc in both AC and DC processes, greater longevity than thoriated tungsten, the ability to use a smaller-diameter electrode for the same job, use of a higher current for a similar-sized electrode, and less tungsten spitting.
