The EZ-T2.0 2% Thoriated Tungsten Electrodes represent the traditional standard for DCEN (Direct Current Electrode Negative) TIG welding. Composed of approximately 98% tungsten and 2% thorium oxide, these electrodes (AWS classification EWTh-2) offer a lower work function than pure tungsten. This metallurgical characteristic allows for easier electron emission, resulting in reliable arc starts at lower voltages and a more stable arc throughout the welding process. The 2.0mm diameter is a specific metric size, offering a current carrying capacity that exceeds 1/16" electrodes while providing finer low-amperage control than 3/32" variants.
One of the primary technical advantages of the EZ-T2.0 is its resistance to electrode erosion. The thorium oxide is evenly dispersed throughout the tungsten matrix, which helps the electrode maintain its ground geometry even under high thermal stress. This retention of the sharpened tip geometry is critical for controlling the arc cone and penetration profile in precision applications. Unlike lanthanated or ceriated alternatives, thoriated tungsten often provides a slightly stiffer arc characteristic that many pipe and pressure vessel welders prefer for root passes and critical joints.
These electrodes are ground to a smooth finish to ensure consistent electrical contact within the collet. They are intended primarily for DC welding on carbon steel, stainless steel, nickel alloys, and titanium. While they can be used on AC in specific setups, they are not typically recommended for aluminum welding due to the tendency of the tip to split rather than ball. Proper ventilation and dust extraction should be used when grinding thoriated tungsten due to the low-level radioactivity of the thorium oxide.
