Tungsten Rod/Electrode

TIG welding is necessary, along with high-quality tungsten electrodes, whenever precisely welded joints, finely made weld seams, and high-quality materials are to be created. For best results in tungsten inert gas welding (TIG), the non-melting, temperature-resistant tungsten electrode is as important as the torch, power source, and shielding gas. There is a huge selection of electrodes for TIG welding. This will the very least encounter the color coding of the tungsten electrodes when selecting the appropriate TIG electrode for a particular welding activity. A distinct color identifies each type of electrode.
