Lincoln Electric has updated its Metalshield line of metal-cored wires with H4 diffusible hydrogen MC-6 and MC-706. The products now feature less than four ml of diffusible hydrogen per 100 grams of weld metal to reduce the risk of porosity and hydrogen-induced cracking in weld deposits. Both are designed for arc welding applications and offer low spatter levels, deoxidizing arc action and high travel speeds.

Metalshield MC-6 (E70C-6M H4) is a mild steel, metal-cored wire for all position welding that provides optimal performance in fast-follow, high travel speed applications. The wire tolerates moderate amounts of surface contaminants and features optimal wetting action, even at low voltages. MC-6's low spatter levels minimize post-weld cleaning, especially when used with Rapid-Arc Waveform Control Technology found in Power Wave equipment.

Metalshield MC-706 (E70C-6M H4) is a mild steel, metal-cored wire for all position welding that is designed for high deposition, high travel speed applications. Metalshield MC-706 offers enhanced silicon island management to minimize slag and cleanup time.
