Low hydrogen type hand electrode, nominal composition (weight percent) is 66Ni-30Cu-3Mn-1Fe, for nickel-copper alloy electrode.
Due to the appropriate amount of Mn and Ti can effectively inhibit the generation of thermal cracks and pores.
Stable arc, beautiful forming, little splash, easy slag removal, good porosity resistance, the mechanical properties of molten metal is stable.
