E3® Starts Faster & Maintains A Stable Arc! Testing has shown that ignition delay with E3® is actually improved over time while thoriated tungsten starts to deteriorate after only 25 starts.
E3® Electrodes Run Much Cooler, Extending Tip Life. E3® electrodes are shown to run approximately 1650° F cooler than thoriated tungsten at the same energy output.
Also available: Pure (EWP) and 2% Thoriated
