IGNITION DELAY OVER TIME

Testing has shown that ignition delay with E3® is actually improved over time while thoriated tungsten starts to deteriorate after only 25 starts.

CURRENT DENSITY VS. TEMPERATURE

E3® Tungsten Electrodes are shown to run 1650 degrees F cooler than Thoriated Tungsten at the same energy output.

YOU CAN SEE THE HEAT

The two electrodes pictures were photographed at the same energy output.

 

E3® ELECTRODES MAINTAIN STABLE TIP GEOMETRY AND THEREFORE A LONGER LIFE
