.020" 2% lanthanated tungsten electrodes blue 7" long

This is New .020" 2% LANTHANATED Tungsten Electrodes (10pc. total) by SEVEN inch long, Color Code BLUE.
2% Lanthanated, BLUE, AWS Class EWLA-2, AC & DC welding applications. Non-Radioactive. Good arc characteristics in ac/dc applications. Applications: carbon & stainless steel,nickel alloys and titanium.
EWLa Electrode Classification.
The EWLa-2 electrodes were developed around the same time as the Ceriated electrodes and for the same reason, that lanthanum is not radioactive. These electrodes contain 2 percent lanthanum oxids (La203), referred to as lanthana. The advantages and operating characteristics of these electrodes are very similar to the Ceriated tungsten electrodes, also called rare earth.
This has been a very popular new material internationally and has recently been introduced in the United States. The 2%content was chosen by two of the largest manufacturers as the optimum content amount based on scientific studies which showed that this content amount most closely mirrors the conductivity characteristics of 2% Thoriated Tungsten. Therefore, welders can usually easily replace their radioactive 2% Thoriated material with this tungsten and not have to make any welding program changes. It makes the switch quick and easy. In addition, one major manufacturer had an independent study performed on this material and it was presented at the 1998 American Welding Society Exhibition in Detroit, Michigan. In summary, 2% Thoriated, 2% Ceriated and two manufacturer's 2% Lanthanated were compared by observing tip erosion after 300 DC arc strikes at both 70 amps and 150 amps. In both cases, the 2%Lanthanated tungsten showed the least amount of tip erosion. This material is also suitable for AC welding. Therefore, if you are considering optimizing your welding, this is an excellent material to consider.
