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% argon/25% CO2. Each can produce diffusible hydrogen levels of less than 4 mL/100 g 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. Dual Shield II 70T-12H4 can be used in construction, heavy equipment fabrication, offshore oil components, shipbuilding, and railcar. Weld metal analysis is similar to E7018
- 24.5 - 29 volt (shielding gas C-25)
- 200 - 500 in./min. wire feed speed (shielding gas C-25)
- 3.8 - 9.9 deposition rate (shielding gas C-25)
- 81.5 - 84.6% efficiency
