Description

Engineered to exact specifications, you can count on these long-lasting electrodes to perform during your most difficult welding application, time and time again. With reliable arc-striking and a low burn-off rate, these electrodes maintain the highest quality of arc while adhering to ANSI and Aussie & U.S Welding standards such as AWS A5.12M/A5.12:2009.

Thoriated tungsten electrodes (AWS classification EWTh-2) contain a minimum of 97.30 percent tungsten and 1.70 to 2.20 percent thorium and are called 2 percent thoriated. They are the most commonly used electrodes today and are preferred for their longevity and ease of use. Thorium increases the electron emission qualities of the electrode, which improves arc starts and allows for a higher current-carrying capacity. This electrode operates far below its melting temperature, which results in a considerably lower rate of consumption and eliminates arc wandering for greater stability. Compared with other electrodes, thoriated electrodes deposit less tungsten into the weld puddle, so they cause less weld contamination.
These electrodes are used mainly for specialty AC welding (such as thin-gauge aluminum and material less than 0.060 inch) and DC welding, either electrode negative or straight polarity, on carbon steel, stainless steel, nickel, and titanium.
During manufacturing, thorium is evenly dispersed throughout the electrode, which helps the tungsten maintain its sharpened edge—the ideal electrode shape for welding thin steel—after grinding. Note: Thorium is radioactive; therefore, you must always follow the manufacturer’s warnings, instructions, and the Material Safety Data Sheet (MSDS) for its use.

Can be used for unalloyed and high-alloy steels; aluminium, titanium, nickel, copper and magnesium alloys; and for microplasma welding.

Over fifty years of experience have culminated into these premium quality TIG welding tungsten electrodes, and you can benefit from that experience.
