71033B - Hobart Megafil 710M Metal-Cored Wire 1/16" 35lb Spool

Technical Overview of Hobart Megafil 710M

The Hobart Megafil 710M is a premium metal-cored welding wire designed for high-performance carbon steel applications. Identified by the internal SKU 71033B, this product comes in a 35-pound spool with a 1/16-inch diameter, making it suitable for industrial fabrication environments requiring high deposition rates and superior weld quality. As a metal-cored consumable, the Megafil 710M combines the high deposition efficiency of solid wire with the wetting characteristics and bead profile control often associated with flux-cored wires, yet with significantly less slag generation.

Metallurgically, this wire is engineered to provide excellent impact toughness properties at low temperatures, specifically maintaining integrity down to -40°F (-40°C). This characteristic makes it an exceptional choice for structural applications exposed to harsh, cold environments where brittle fracture is a concern. The wire is formulated to operate with a mixed shielding gas, specifically requiring a blend of 75-95% Argon with the balance being Carbon Dioxide (CO2). This gas mixture promotes a stable spray transfer mode, reducing spatter and ensuring deep penetration.

The Megafil 710M is particularly noted for its versatility in both automatic and mechanized welding setups. Its consistent feedability and arc stability make it a reliable choice for robotic cells where downtime must be minimized. Furthermore, it is qualified for root pass welding on pipe, a critical application in process piping industries. By utilizing this metal-cored wire, fabricators can achieve higher travel speeds compared to solid wires in similar applications, leading to increased throughput and productivity without compromising the mechanical properties of the weldment.

In summary, the Hobart Megafil 710M represents a sophisticated solution for heavy industrial welding. Its formulation addresses the needs of heavy equipment manufacturing, process piping, and general fabrication, providing a balance of mechanical robustness and operational efficiency.
