Characteristic : 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.
