The red tungsten welding rod is used for welding steel, stainless steel, nickel, and titanium, providing high welding current. The gold-colored tungsten welding rod is similar to the red one and works well with both direct current (DC) and alternating current (AC). Its key feature is that it does not emit harmful radiation or substances, making it safer for users who need to weld for extended periods. The green tungsten welding rod contains pure tungsten and is ideal for welding aluminum and magnesium. It is used with AC and does not require sharpening of the tungsten tip.
