2% Thoriated Tungsten Electrode(color mark :red )EWTh -2/WT20:

1.It is the most common type of Tungsten used today .easier arc starting capabilities ,more stable arc and have good performance for DC.and they contain 2%thoriated .

These electrodes are used mainly for specialty AC welding (such as thin-gauge aluminum and material less than 0.060 inch) and DC welding, either electrode negative or straight polarity, on carbon steel, stainless steel, nickel, and titanium.

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.
