Which welding current is best suited for ceriated tungsten electrodes?

Ceriated tungsten electrodes are known for their excellent performance in both AC and DC welding applications. However, they provide optimal arc stability and a higher clean-up effect when used with DC current, especially at lower current settings. The low current setting helps to improve control over the heat input and results in a more stable arc, which is especially beneficial when welding thin materials or managing heat-affected zones.

Using ceriated tungsten electrodes at low DC current settings can enhance the quality of the weld by minimizing the risk of overheating and warping the base materials. This ability to maintain a stable arc at lower currents is a distinct advantage, allowing for precision welding while maintaining the integrity of the workpieces.

In contrast, while ceriated tungsten electrodes can be used with AC or high current settings, those applications may not yield the same level of control or stability as when employing low DC settings.
