It is widely used as an additive oxide electrodeIt has much more advanced comprehensive welding property than the properties of pure tungsten electrode and other additive oxide electrodesIt is not replaced by other oxide electrodes during the long use process.It can be operate easily and electric current load is big， it can produce arc easily and steadily， the gap of the breaking arc is big ， loss less and long life， if has much higher recrystallizing temperature， much better conductivity and better mechanical cutting property， it is used for welding carbon steel， stainless steel， nickel alloy and titanium metal， it is a first selection material for high quality welding.2% Thoriated WT20 Red TIG Welding Tungsten ElectrodeSize: 1/16"x6"(1.6mmx150mm)Quantity: 10pcs/setPackage Included:1 X TIG Welding Tungsten Electrode
