525241025H - Hobart SubCOR SL 745 3/32" Metal-Cored SAW Wire, 55lb Coil

High-Efficiency Metal-Cored Wire for Submerged Arc Welding

The Hobart SubCOR SL 745 is a premium metal-cored wire designed specifically for the submerged arc welding (SAW) process. Engineered to outperform traditional solid wires in deposition efficiency, this 3/32-inch (2.4mm) diameter wire utilizes a composite core structure that increases current density at equivalent amperage settings. This results in significantly higher melt-off rates and faster travel speeds, making it an ideal choice for industries prioritizing throughput and productivity in heavy fabrication environments.

Manufactured by Hobart, a leader in welding filler metals, the SubCOR SL 745 ensures consistent chemistry and mechanical properties across the entire coil. The metal-cored construction not only aids in deposition but also contributes to a smoother arc and improved wetting action, which helps eliminate common defects such as undercut or lack of fusion when parameters are optimized. It is formulated to work synergistically with Hobart’s range of fluxes (such as the SWX series) to produce sound welds with excellent slag release, reducing post-weld cleaning time and labor costs.

This product is supplied in a 55 lb (25 kg) coil, a standard format for industrial SAW equipment, balancing portability with run-time duration. The wire is suitable for welding carbon steels in both single-pass and multi-pass applications, commonly found in structural steel erection, heavy equipment manufacturing, and general fabrication. By choosing Hobart SubCOR SL 745, facilities can leverage the benefits of cored wire technology—such as broader penetration profiles and higher deposition rates—while maintaining the reliability expected from the SubCOR brand.
