Description: Lanthanum electrode is lanthanum oxide, providing better welding performance. It is used for DC welding of stainless steels, nickel alloys, aluminum and many other metal. Lanthanum electrodes are most used to replace thorium electrodes, and it is easier to create an electric arc with a longer life. Features: Lanthanum electrodes have excellent welding performance. Easy to create an electric arc, eco-friendly and no radioactivity. Suitable for DC small current operation, burn faster under large current. It is the best choice for welding stainless steel and thin metal plate. Well packed and protected in a plastic box, not worry to be broken.
