Tri-Mix Tungsten Electrode is the Tungsten material with two or more rare earth oxide additives. Every additive works to the benefit of others and serves as a complement at the same time to make its welding performance more outstanding. Applications: Tri-Mix Tungsten Electrode is normally applied in DC(Direct Current) welding, it also works well in AC welding. It widely used as an additive oxide electrode, having much more advanced comprehensive welding performance than the properties of Pure Tungsten Electrode and other additive oxide electrodes. Good for low-alloyed steels, non corroding steels, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys.
