73115B - Hobart Megafil 731B .045 Metal-Cored Wire 35lb Spool

Heavy-Duty E110C Metal-Core Wire

Tackle your toughest high-strength steel projects with Hobart Megafil 731B .045" welding wire. This metal-cored wire is built for performance, delivering the strength needed for heavy equipment, crane manufacturing, and structural steel fabrication. Rated E110C-K4, it provides the high tensile strength (110 ksi) required for demanding jobs while maintaining excellent ductility and toughness in cold environments.

What sets the Megafil 731B apart is its seamless construction. Unlike folded wires, this wire is a solid tube filled with flux and copper-coated, preventing moisture pickup and ensuring a long shelf life. For the welder, this means a consistent, high-quality arc with very low hydrogen levels, reducing the risk of cracking in thick materials. You get the speed and deposition benefits of a flux-cored wire with the cleanliness and efficiency of a solid wire.

Packaged in a 35 lb spool, this wire is ready for serious production work. It runs smoothly on standard CV equipment in flat and horizontal positions, and can be used out-of-position with pulsed MIG capabilities. With minimal spatter and almost no slag to chip, you spend more time welding and less time grinding. Upgrade your high-strength welding game with the reliability of Hobart Megafil.
