Gold Plus tungsten electrodes contain a minimum of 97.80% tungsten and 1.30 to 1.70% lanthanum. Gold Plus electrodes work well on AC or DC welding and can maintain a sharpened point. These products can be used to replace both ceriated and thoriated because, unlike thoriated tungsten, these electrodes are suitable for AC welding and, like ceriated electrodes, they allow for lower voltage arcs. Features and Benefits Excellent arc starting ability to allow for quick and precise working Possesses a low burn off rate to ensure there is no wastage of your material Good arc stability and excellent re-ignition characteristics Can replace both ceriated and thoriated electrodes making it a versatile product Typical Applications Ideal for use when welding titanium alloys, copper alloys, non-corroding steel and nickel alloys
