2% lanthanated tungsten electrodes (AWS classification EWLa-2), which contain a minimum of 97.80% tungsten, 1.80 to2.20% lanthanum, has been the most popular alternative to 2% thoriated tungsten electrode for most applications in American ,Europen countries and Japan. It can be used for both AC and DC welding with both inverter and transformer power sources.This tungsten electrodes have much longer life than 2% thoriated tungsten electrodes if not overloaded and better arc starting.


Application

Unlike thoriated tungsten, these lanthanated wolfram electrodes are suitable for AC welding and, like ceriated electrodes, allow for the arc to be started and maintained at lower voltages.
