The 2% Thoriated Tungsten Electrodes (3/32" x 7") are the traditional choice for professional TIG welders requiring precision and consistency. Classified as EWTh-2 and identified by a Red color code, these electrodes contain a minimum of 97.30% tungsten and 1.70% to 2.20% thorium oxide. This composition significantly improves electron emission, allowing for easier arc starting and a higher current-carrying capacity than pure tungsten alternatives.
Designed primarily for DC Electrode Negative (DCEN) applications, these electrodes excel in welding carbon steel, stainless steel, nickel alloys, and titanium. The thorium oxide is evenly dispersed throughout the electrode, which helps the tungsten maintain a sharpened edge for longer periods, reducing the frequency of regrinding. This stability makes it an excellent choice for critical welds where arc wander must be minimized.
While thoriated tungsten is renowned for its performance, users should be aware of safety protocols regarding the grinding dust due to the low-level radioactivity of thorium. Proper ventilation and dust collection are recommended during preparation. This economy pack offers a cost-effective solution for shops that go through consumables regularly but demand the reliable arc characteristics that only thoriated tungsten can provide.
