Pure Tungsten Electrode Properties
Pure Tungsten Electrode Properties
Compared with impure tungsten electrodes,pure tungsten electrode has the lowest current capacity and is the least expensive. When conducted alternating current, it can maintain a clean balled end.
What’s more, pure tungsten electrodes are more prone to weld contamination than other types of tungsten electrodes. Pure tungsten electrodes tend to spit at higher currents and used for non-critical welds only.
For its physical properties, pure tungsten electrode has the minimum content of 99.95% tungsten. they can be classified from their ends color from other tungsten electrode. For example, pure tungsten electrodes are green end, but thoriated tungsten electrode is red end.
