We have several types Tungsten electrodes for TIG welding, Cerium-Tungsten





 Electrodes, Thorium-tungsten Electrodes, Lanthanum tungsten Electrodes, Zirconium





 tungsten Electrodes and others.





 1) WCe20 Cerium-Tungsten Electrode has good starting arc performance, low melting





 rate, long welding life, it is mainly used for welding under the condition of low current.





 2) WT10, WT20, WT30, WT40 Thorium-tungsten Electrode operates well even when





overload with extra amperage, it is used for DC applications.





 3) WL10, WL15, WL20 Lanthanum tungsten Electrode can be able to bear high current





and have the lowest burn-lost rate, it is a popular tungsten electrodes in the circle of





welding.





 4) WZr8 Zirconium tungsten Electrode has good corrosion resistance and good





performance in AC welding.





 Specification: 0.5-12.0mm diameter, L=150, 175mm or according to the customer's





request.





Cerium-tungsten electrode is the electrode of tungsten added with 2%of CeO2.The





power of its electronic transgression is 2.4ev,less than that of thorium-tungsten





electrode .Its arc derivation voltage is also lower with better arc derivation function





and higher arc power stability.The current allowed under the condition of anode direct





current is higher and the burn spoilage is smaller.





 　Cerium-tungsten electrode,a new type of non-radiate electrode material invented in





China,can not only replace the thorium-tungsten electrode in the case of low direct





current and mini-scaled welding but also bears superior features over the latter.
