THORIATED “RED TIP” TUNGSTENS 150MM (PACK OF 10)
A pack of 10 thoriated tungstens (red tip) 150mm in length. Choose from the dropdown above for Tungsten sizes.
Thoriated tungsten electrodes are the most commonly used today, preferred by many for their longevity and ease of use. Often referred to as 2% thoriated, they contain a minimum of 97.30 % tungsten and 1.7 – 2 % thorium. The thorium improves arc start and allows for a higher current capacity due to the increased electron emission qualities of the electrode. Thoriated tungstens operate far below their melting temperature. Because of this, the tungstens are consumed less in the welding process and tend to deposit less into the weld puddle, minimising contamination.
Thoriated tungstens can be used in DC negative or straight polarity on carbon steel, stainless, titanium and nickel.
Also suitable for speciality AC welding (such as thin gauge aluminium)
During manufacturing, thorium is evenly dispersed throughout the electrode, which helps the tungsten maintain its sharpened edge—the ideal electrode shape for welding thin steel—after grinding.
Note: Thorium is radioactive; therefore, you must always follow the manufacturer’s warnings, instructions, and the Material Safety Data Sheet (MSDS) for its use.
