Dual Shield II 712X H4 is an all position flux cored wire intended for applications requiring outstanding weld metal toughness. This X-Series wire in combination with 75% Argon/25% CO2 shielding gas, provides a smooth arc, and low spatter levels characteristic of Dual Shield flux cored wires. Dual Shield II 712X H4 applications include off-shore oil components, shipbuilding and heavy equipment where exceptional Charpy impact/low temperature toughness is required.
