good quality WT20 welding electrode 1. It is fine and close product with grey metallic luster. 2.. Diameter: 16mm-100mm
Thoriated tungsten electrode is the most widely used welding material. 2% Thoriated Tungsten contains 2% thorium oxide (ThO 2 ) that is dispersed inside the whole length of the Tungsten rod.2% Tungsten electrode provides excellent resistance from weld pool contamination and offers the welder easier arc starting capabilities and a more stable arc. Application : Generally used for DC electrode negative or straight polarity applications such as carbon & stainless steels, nickel alloys and titanium.
