Tungsten Electrode - Pure (Green Tip)
For aluminum TIG welding, pure tungsten has been the traditional electrode
choice because of its low cost and availability in ground condition. But for
improved current-carrying capacity and to minimize tungsten transfer across the
arc, zirconiated tungstens work best. Balls easily, low cost, tends to spit at
higher currents, used for non-critical welds only.
