Grey ceriated electrodes are popular due to their extreme ease of striking an arc with lower amperages, and their extraordinary performance with regard to DC welding applications. They perform best with titanium alloys, copper alloys, magnesium alloys, aluminum alloys, nickel alloys, non-corroding steels, and low-alloyed steels.

WC20 Welding cerium Tungsten Electrode
Cerium-tungsten electrode is a non-radiative and green products .It has good starting arc performance under the condition of low current .It is known to be especially good for direct current welding with low amperage because it starts very easily at low amps .Therefore it is very popular to be used for the welding of pipeline ,fine parts, short welding cycles and given number welding .
