Lincoln Electric introduces Metalshield MC-90 and MC-110 low-alloy metal-cored welding wires designed to produce the strong, H4-diffusible hydrogen weld deposits required in applications such as heavy equipment and crane fabrication. Key features include low spatter as well as improved arc stability and silicon island management to minimize slag and ease slag removal. Wires offer low temperature impact properties and are capable of 40 J (30 ft·lb) at -51°C (-60°F). Deoxidizing agents minimize pre- and post-weld cleanup. Both wires are suitable for semi-automatic and robotic applications and are available in 500-lb (227-kg) Accu-Trak drums as well as 33-lb (15-kg) plastic spools in standard diameters of 0.045, 0.052, and 0.625 in (11.4, 1.32, and 1.6 mm).
