The XTRweld 1.5% Lanthanated Tungsten Electrodes are ideal for GTAW (TIG) welding applications. Lanthanated tungsten electrodes have excellent arc starting, a low burnoff rate, good arc stability, and excellent reignition characteristics, they also share the conductivity characteristics of 2% thoriated. In some cases, 1.5 & 2% lanthanated can replace thoriated without having to make significant welding program changes. Working well on AC or DC electrode negative with a pointed end, tungsten electrodes can also be balled for use with AC sine wave machines. Maintaining a sharpened point is an advantage, useful for welding steel and stainless on DC or AC from square wave power sources. Pack of 10 electrodes.
