TUNGSTEN ELECTRODES by Platinum North America

High performance tungsten electrodes that have undergone rigorous testing to ensure the highest quality and durability. Available in 6 varieties including the unique RE4 (Rare-Earth) purple tip tungsten electrodes that are suitable for DC and AC TIG welding and can be used in place of virtually all other types of tungsten for convenience and hazard-free performance.

• Facilitate arc starting


• Increase arc stability


• Improve current carrying capacity of the electrode


• Reduce risk of weld contamination


• Increase electrode life

Oxides used are primarily zirconium, thorium, lanthanum or cerium. Additions are usually 1% – 4%. These oxides greatly improve arc initiation, especially when direct current (DC) welding is employed. Thorium oxide (thoria) has been used for many years, having been found effective in terms of long life and thermal efficiency. Zirconium oxide (zirconia) has been com
