Each of the new Dual Shield II H4 wires is an all-position flux cored wire that provides excellent low temperature toughness in both the as welded and/or stress relieved conditions (as applicable) when used with 75% Ar / 25% CO2. Each can produce diffusible hydrogen levels of 4 mL/100g over a wide range of welding parameters. Dual Shield II 70T-12H4 also provides the smooth arc and low spatter levels characteristic of other Dual Shield II wires. Weld metal analysis is similar to E7018.
