Dual Shield II 70 Ultra is an all-position flux cored wire that displays exceptional impact properties when used with 75% Ar/25% CO2. The improved properties qualify this wire to the Navys "HY" classification. The "Ultra" series produces smoother arc characteristics and lower welding fumes. Dual Shield II 70 Ultra was developed to join low and medium carbon steel. The Military classification allows Dual Shield II 70 Ultra to be used for attaching steels of less than 81 ksi (560 MPa) yield to HY-80 and HY-100. Commercial applications include construction, shipbuilding, railcar, and heavy equipment industries.
