Gray tungsten welding rod is suitable for low DC current welding. It can also be used for welding aluminum with AC current. It is ideal for welding thin materials or for automatic welding applications.

Available in various sizes suitable for different tasks. 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 beneficial for users who need to weld for long periods. The gold-tipped tungsten welding rod and the green tungsten welding rod, which contains pure tungsten, are ideal for welding aluminum and magnesium. They work with alternating current (AC) and do not require sharpening the tungsten tip.
