FLUXOFIL M 42 is a seamless copper coated metal cored wire for welding of high strength steels with minimum yield strength of 690 MPa with outstanding welding characteristics in the short-arc and spray-arc ranges. Almost spatter-free when welding in the spray-arc range. Good restriking, even with a cold wire tip, this being suitable for robotic applications. Characteristic features: good side wall fusion, smooth and finely rippled welds without undercut into the base metal. Little formation of silicates on the weld surface, so that multi-pass welds can be made without inter-run cleaning. Due to the easily controllable weld pool in the short-arc range, FLUXOFIL M 42 is suitable for positional welding.
