The innovative Rare Earth Mix electrode is an excellent substitute for the traditionally favored red thoriated type and boasts the same high performance properties. It's best used when welding Aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys, low-alloyed steels, and non-corrosive steels.
The mult-ivariate rare-earth tungsten electrode is designed to balance the migration rate and evaporation rate of the internal electron, which makes the tungsten electrode performance to the extreme and reduces the electron escape work of the electron.It's easy to get up and repeat the arc and mix it with the same different oxides and if the welding cycle is longer than 15 minutes, it's going to last longer.
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, aluminium, 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.
The performances of Composite Electrodes in welding can be much improved by adding two or more rare earth oxides which are mutually completementary.
