1. WT20 -2% Thoriated Tungsten Electrodes Thoriated Tungsten electrodes are the most commonly used tungsten material, Thoria is low-level radioactive material, but it is was the first to display a significant improvement over pure tungsten. Application : Thoriated tungsten electrodes are generally used for DC electrode negative or straight polarity applications such as carbon & stainless steels, nickel alloys and titanium, as they operate well even when overload with extra amperage, and then improve the performance of welding. Diameter:1.6/2.0/2.4/3.0/3.2/4.0/4.8mm Length:150/175mm
