Cerium-Tungsten Electrode is a nonradiative and green product.It can stare performing arc with a low current.It is known to be especially good for direct welding with low amperage because it starts very easily at low amps.Therefore it is very popular in welding of pipeline,fine pares short welding cycles and given number welding.
Non-radioactive tungsten electrode products have excellent arcing performance under low current conditions, arc current is small.
Cerium tungsten electrode is suitable for DC welding at low voltage, because it is easy to arc at low voltage, and it is 10% lower than thorium tungsten at work.
It suitable to pipe welding, cerium tungsten electrodes are the most popular and are also commonly used to weld small parts.
