Review of Selecting The Right Tungsten--A Critical Issue To Get The Full Benefits of AC TIG Inverter Welding

For as long as anyone can remember, the prevailing wisdom was that in order to get the best results, anyone who was TIG welding aluminum, magnesium or other alloys that required an AC arc had to use a pure tungsten electrode.

But not anymore. For the last five years the industry has made a dramatic shift toward inverter-based AC TIG welders that incorporate advanced squarewave technology to improve weld quality, increase travel speed and reduce operating costs.

However, in order to gain the maximum benefits from inverter technology, selecting the right tungsten now becomes an increasingly more critical issue. In the past, pure tungsten was the only choice for AC TIG welding. But that's no longer the case with the latest inverter technology. Today, industry experts recommend against pure tungsten in favor of the new "rare earth" tungstens. By adding elements such as cerium or lanthanum these electrodes outperform pure tungsten.
