FAQ
Q: What is WT20 tungsten?
A: WT20 (EWTh-2) is a 2% thoriated tungsten electrode identified by its red color. It is widely used for DC TIG welding because of its excellent arc stability, easy arc starting, and long service life.
Q: Is WT20 suitable for AC or DC welding?
A: WT20 is primarily designed for DC TIG welding and delivers excellent performance on carbon steel, stainless steel, nickel alloys, titanium, and other ferrous metals.
Q: Why is the aluminum tube packaging better?
A: The sealed aluminum tube helps protect the electrodes from oxidation, moisture, and physical damage during storage and transportation while making them easy to carry in a toolbox or welding kit.
Q: Which diameter should I choose?
A: Smaller diameters are suitable for thin materials and lower welding currents, while larger diameters are recommended for thicker materials and higher current applications.
