Blue Demon EWCe-2 2% ceriated electrodes are tungsten electrodes with around 2% cerium oxide (ceria). These electrodes offer easy starting, better arc stability, and a lower vaporization or burn-off rate. They're non-radioactive and work well with both AC and DC polarity as per AWS A5.12. Sizes range from .40 to 5/32, and the dimensions are 8 x 3 x 1 inches.
Using these Blue Demon 2% ceriated tungsten electrodes is easy. First, select the right size according to your welding needs, which range from .40 to 5/32. You can use them with either AC or DC polarity for successful operation. When starting your welding job, you'll notice they start up easily and keep the arc stable throughout. Since they're non-radioactive, you don't have to worry about any harmful radiation. For maintenance, keep them in a dry place to prevent any damage. Avoid dropping or hitting them hard as this could affect their performance. If you notice a high rate of vaporization or burn-off, it might be time to replace the electrode.
