E3 3/32 TIG WELDING TUNGSTEN ELECTRODES REPLACES 2% TUNGSTEN E3 1/8 TIG WELDING TUNGSTEN ELECTRODES REPLACES 2% TUNGSTEN E3 1/16 TIG WELDING TUNGSTEN ELECTRODES REPLACES WT20 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 Size: 1.2mmx175mm 2.0mmx175mm 2.4mmx175mm 3.0mmx175mm 3.2mmx175mm 4.0mmx175mm 5.0mmx175mm 1.2mmx150mm 2.0mmx150mm 2.4mmx150mm 3.0mmx150mm 3.2mmx150mm 4.0mmx150mm 5.0mmx150mm Black rod * 2.0mmx450mm * 2.4mmx450mm * 3.0mmx450mm * 3.2mmx450mm * 4.0mmx450mm * 5.0mmx450mm * 6.0mmx450mm * 8.0mmx450mm Polished * 800-1000mm in length
