Blue Demon's True Flex Tungsten is the welding industry's only bendable tungsten electrode.  This tungsten bends at room temperature, and helps solve problems like tight angles or spaces that you previously could not access. This tungsten works well for both AC TIG (aluminum) and DC TIG (steel) applications, as well as transformer and inverter power sources.  The light blue tip color is a rare earth mixture, classified as EWG.
