2% THORIATED RED. The most commonly used tungsten in the United States. This tungsten is used primarily in DC welding. It has a low work function and provides a high load and amperage capability. The health safety issue of 2% Thoriated tungsten has recently raised concerns regarding inhalation and disposal of the Thorium. Wolfram Standard material only.

Thoriated tungsten electrodes is currently one of the best varieties of tungsten electrode welding performance, the work function is low, effectively reduce the welding pollution, and high carrying capacity, easy arc starting and stability, long service life, high market share.
A few of the advantages of using thoriated tungsten electrodes in industry include easier are starting, greater stability, and reduced weld metal contamination. The electrodes used in this evaluation contained 2% thoria (thorium oxide) and were either mm or mm in diameter.
Thorium, in the form of thorium oxide, is added to tungsten welding electrodes which are used in Tungsten Inert Gas (TIG) arc welding. The addition of thorium improves arc starting and stability, reduces weld contamination and gives longer electrode life. However, thorium is a naturally occurring radioactive element and as such poses a ...
WT electrodes: Slightly radioactive due to addition of thorium; Refrain from using due to increased health risks; Improved ignition characteristics and better current carrying capacity compared to WP electrodes; WZ electrodes: Lower risk of contamination of weld thanks to addition of zirconium; Tungsten electrodes for AC welding of aluminium alloys
Thoriated TIG welding electrodes with 2 % thorium oxide (colour code red) are currently the most widely used electrodes worldwide. Thorium is however a radioactive element and as such represents a potential danger to health and environment. Thorium is a socalled "aemitter," but when enclosed in a tungsten matrix, the "a" radiation emitted externally is negligible. The danger to the welder arises when thorium .
