71034B - Hobart Megafil 710M 1/16-inch Metal-Cored Wire 550lb Drum

Hobart Megafil 710M Metal-Cored Wire (1/16" - 550lb Drum)

The Hobart Megafil 710M is a premium metal-cored welding wire designed for high-demand industrial applications involving carbon steel. Engineered to meet AWS E70C-6M H4 classifications, this wire provides exceptional mechanical properties, including superior impact toughness down to -40°F. This makes it a preferred choice for industries operating in harsh environments, such as heavy equipment manufacturing, railcar construction, and offshore fabrication. The 1/16-inch diameter allows for high current carrying capacity and significant deposition rates, optimizing productivity in large-scale operations.

One of the standout features of the Megafil 710M is its formulation for use with mixed shielding gases, specifically 75-95% Argon with a Carbon Dioxide balance. This gas mixture, combined with the metal-cored design, produces a smooth, stable arc with minimal spatter. The result is a high-quality weld bead with excellent wetting characteristics and very little slag, significantly reducing post-weld cleanup time and labor costs. The wire is also formulated to provide deep penetration, making it suitable for critical structural welds and even root pass welding on pipe without the need for a backing bar in certain configurations.

Packaged in a substantial 550lb drum, this product is specifically targeted at high-volume manufacturing environments, including automatic and robotic welding cells. The bulk packaging reduces the frequency of spool changes, thereby maximizing arc-on time and overall throughput. The wire's consistent cast and helix ensure trouble-free feeding through long conduit runs, which is essential for automated systems. Furthermore, the H4 low-hydrogen designation ensures that the weld deposit is resistant to hydrogen-induced cracking, providing peace of mind for critical structural applications.

Whether utilized for process piping, general fabrication, or heavy machinery, the Hobart Megafil 710M delivers consistent, high-quality results. Its ability to handle varying fit-ups and its robust mechanical properties make it a versatile solution for modern fabrication shops looking to enhance efficiency and weld quality simultaneously.
