Tungsten Electrodes (Thoriated) WT 20 - Set of 10 Pieces: The Thoriated Tungsten Electrodes (WT 20) set contains 10 high-quality electrodes designed for DC welding applications. Known for their robustness and durability, these electrodes are widely used for their stable arc, ease of striking, and low burn-off rate. Ideal for welding ferrous metals, such as steel and stainless steel, the thoriated electrodes offer excellent performance under high current loads. They are well-suited for demanding industrial applications where reliability and consistent weld quality are paramount. Despite their radioactive properties, they are favored by many professional welders for their extended electrode life and superior performance.
