Availability: In stock

The EWTh-X electrodes are tungsten electrodes containing thorium oxide, referred to as thoria. The thoria in all classes is responsible for increasing the usable life of these electrodes over the EWP electrodes because of their higher electron emission, better arc starting and arc stability. They generally have longer life and provide greater resistance to tungsten contamination of the weld.
