Blue Demon Ceriated Tungsten Electrodes have excellent characteristics and can be used on a wide variety of applications. Ceriated Tungsten Electrodes (EWCe-2) contain about 2% cerium oxide, referred to as ceria. These electrodes were first introduced into the US market in 1987. Several other grades of this type of electrode are commercially practical, including electrodes containing 1% ceria, but only one grade. EWCe-2 has been incorporated in this specification as having commercial significance. The advantages of tungsten electrodes containing ceria compared to pure tungsten include increased ease of starting, improved arc stability, and reduced rate of vaporization of burn-off. Unlike thoria ceria is not a radioactive material. These advantages increase with increased ceria content. These electrodes operate successfully with AC or DC, either polarity. Sold in packs of 10.
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
WARNING: The wires of these products contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
