71016B - Hobart Megafil 710M .045 Metal-Cored Wire 660lb Drum

Technical Overview of Hobart Megafil 710M

The Hobart Megafil 710M is a premium metal-cored welding wire designed for high-performance joining of carbon steels. This specific product comes in a high-volume 660 lb drum, identified by SKU 71016B, making it an optimal choice for industrial manufacturing environments utilizing automatic or robotic welding cells where downtime for consumable changeover must be minimized. The wire features a 0.045-inch diameter, a standard size for structural and heavy fabrication applications that require a balance between deposition rate and heat input control.

Metallurgically, the Megafil 710M is formulated to meet AWS E70C-6M classifications. It is engineered to operate with a mixed shielding gas, specifically 75-95% Argon with the balance being Carbon Dioxide. This gas mixture, combined with the metal-cored design, promotes a smooth spray transfer mode with minimal spatter and excellent arc stability. One of the defining technical characteristics of this wire is its superior impact toughness; it maintains excellent mechanical properties down to -40°F (-40°C), making it suitable for critical structures exposed to harsh, cold environments.

The wire is capable of welding in multiple positions, though it excels in flat and horizontal applications typical of heavy equipment manufacturing and process piping. It is also noted for its ability to perform root pass welding on pipe, a capability that distinguishes it from many other metal-cored wires. The slag system is designed to be minimal, often appearing as small islands that are easily removed, which facilitates multi-pass welding without extensive inter-pass cleaning. This product is strictly for DCEP (Direct Current Electrode Positive) polarity.
