Product Description
Weldmark 1.5% Lanthanated TIG Electrodes – Gold Tip, Ground Finish
Versatile Performance. Built for Precision TIG Welding.
Weldmark 1.5% Lanthanated Tungsten Electrodes are a top-tier choice for welders looking to maximize performance across a wide range of TIG applications. With a gold tip for fast, at-a-glance identification and a clean ground finish for reliable starts, these electrodes combine the best of both AC and DC welding characteristics—delivering superior arc starts, stability, and low burnoff even under demanding conditions.
Made with 97.80% tungsten and 1.30–1.70% lanthanum, Weldmark lanthanated electrodes retain a sharpened point longer than thoriated or ceriated options, making them especially effective for DC welding on steel and stainless steel, as well as AC welding when balled or used with square wave power sources.
