ECOspark 6-NC is a solid wire for mild steel, supplied without a copper coating. It works on welded structures, halls, frames, machine parts and repairs of structural steel.
Among the parent materials it covers S235JR, S355JR, S235JO, S355JO, S235J2, S355J2 and S275N. Leaving out the copper coating limits liner fouling and copper in the fumes.
