Product Description
WC20 Ceriated Tungsten Electrode for tig Welding 1) Ceriated tungsten electrodes (AWS classification EWCe-2) contain a minimum of 97.30 percent tungsten and 1.80 to 2.20 percent cerium and are referred to as 2 percent ceriated. These electrodes perform best in DC welding at low current settings but can be used proficiently in AC processes. With its excellent arc starts at low amperages, ceriated tungsten has become popular in such applications as orbital tube and pipe fabricating, thin sheet metal work, and jobs involving small and delicate parts. Like thorium, it is best used to weld carbon steel, stainless steel, nickel alloys, and titanium, and in some cases it can replace 2 percent thoriated electrodes. Using ceriated electrodes at higher amperages is not recommended because higher amperages cause the oxides to migrate quickly to the heat at the tip, removing the oxide content and nullifying its process benefits. 2) Color mark: Grey (WC20 / EWCe-2) 3) Diameter:1.0mm - 10.0mm 0 .040" (1.0mm), 1/16" (1.6mm), 3/32" (2.4mm), 1/8" (3.2mm) and 5/32" (4.0mm) 4) Length: 6'' (150mm), 7''(175mm) 5) Quality of surface: ground finish, polish finish 1) 10 pieces red welding electrodes rods put into 1 plastic box, or plastic bag is available as client's requirement. 2) Then packed in one carton box.
