Blue Tip TungstenTIG Tungsten Electrodes Blue Tip (2% Lanthanated) The Blue Tip TIG Tungsten Electrodes (2% Lanthanated) are high performance, non radioactive electrodes designed for exceptional arc stability, long life, and easy ignition. With 2% lanthanum oxide (LaO), these electrodes offer superior conductivity and performance compared to pure or thoriated tungsten making them ideal for both AC and DC TIG welding. They deliver smooth, stable arcs with minimal
