The NORTH 2% Thoriated 4.0mm Tungsten Electrode by IWWS is a premium welding consumable designed for professional welders requiring reliable arc performance. This electrode contains a nominal 2 wt-% thorium oxide (ThO2) uniformly distributed throughout its length, making it the most commonly used tungsten type in TIG welding.

Thoriated tungsten electrodes offer excellent resistance to weld pool contamination, ensuring cleaner welds and longer electrode life. They provide easier arc starting and a more stable arc, which enhances welding precision and control. These electrodes are primarily intended for DC electrode negative (straight polarity) applications and are suitable for welding carbon steels, stainless steels, nickel alloys, and titanium.
