2% Thoriated Tungsten Electrode

2% thoriated tungsten electrode contains 97.30% of tungsten (minimum) and 1.70 - 2.20% of thorium. Nowadays it is the commonly used electrode, which is preferred for its longevity and ease of operation. Thorium can increase the electron emission quality of the electrode, improve arcing property and allow for higher current carrying capacity. The kind of electrode can work far below its melting temperature, which results in considerably lower rate of consumption and eliminates arc wandering for greater stability. It also has lower level of weld contamination than other electrodes.

Unlike pure tungsten, thoriated tungsten electrode is only for AC welding, but it is exceptional for DC electrode negative or straight polarity on carbon and stainless steel, nickel and titanium applications. During manufacturing, thorium is evenly dispersed throughout the electrode. This evenness allows the electrode to maintain a sharpened edge—the ideal electrode shape for welding thin steel. Sharpening the electrode’s point, however, should be done with great care. Thorium is radioactive; therefore, you must always follow manufacture’s warnings, instructions and the MSDS (Material Safety Data Sheet) for its use.
