Gold Plus tungsten electrodes contain a minimum of 97.80% tungsten and 1.30 to 1.70% lanthanum. These electrodes have excellent arc starting, low-burn-off rate, good arc stability and excellent re-ignition characteristics.
Gold Plus electrodes work well on AC or DC electrode negative with a pointed end or they can be balled for use with AC sine wave power sources. These electrodes maintain a sharpened point well and can 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. The 1.5% lanthanum increases the maximum carrying capacity by approximately 50% for a given size electrode and they are outstanding in the low current range.
