Lanthanated tungsten electrodes are suitable for AC welding, allow the arc to be started and maintained at lower voltages. They work well on AC or DC electrode negative with a pointed end, or they can be balled for use with AC sine wave power sources. Maintains a sharpened point well, which is an advantage for welding steel and stainless steel on DC or AC from square wave power sources. These electrodes have excellent arc starting, a low burnoff rate, good arc stability, and excellent reignition characteristics.
Composition: 98,5% tungsten and 1,5% lanthanum oxide.
