Engineered blend of oxides outperforms other electrode types.

E3® Electrodes Run Much Cooler, Extending Tip Life!

E3® electrodes are shown to run approximately 900° Kelvin or 1650° F cooler than thoriated tungsten at the same energy output.

 

 

The 2 electrodes pictured were photographed  at the same energy output.

Clearly you can see the E3® electrode has a much smaller heat affected zone.
