      Use E3 all of the time, this is about as cheap as I can get it with my school discount, from the local welding supply shop

      Welds nicely.

      I'm very new to TIG welding. These weld very nicely. Good arc control and I like I can use the same electrode for different metals.

      Best out there. PERIOD!

      Lasts forever. Great on mild, stainless, and aluminum. I can get needle point sharp ends by using a belt sander and chucking the tungsten in a drill. I switched to this tungsten when it first came out and I own a Fabrication shop and this tungsten has by far helped my quality of welds and increased production.

      good electrodes

      these electrodes seem to work a lot better than the thoriated ones
