E3 1/16 X 7 Ground Tungsten Electrodes Pkg/10 Replaces 2% Thoriated Tungsten

E3 Tungsten Electrodes deliver superior arc starting, electrode lifetime, and overall cost effectiveness. Users of 2% thoriated tungsten can switch to E3 tungsten with confidence. E3 requires fewer re-grinds and provides longer overall lifetime when compared to 2% thoriated. E3 tungsten can be used on DC electrode positive or negative with a pointed end, or balled for use with AC power sources. Featues over Thoriated Tungsten • Lower operating temperature • Fewer re-grinds • Improved arc starting • Versatile use
