Hobart FabCO Excel-Arc 71 Flux-Cored Wire

The Hobart FabCO Excel-Arc 71 is a premium gas-shielded flux-cored wire designed for the welding of mild and low-alloy steels. Engineered with a fast-freezing slag system, this wire excels in all-position welding, particularly in vertical-up and overhead orientations where puddle control is critical. It meets AWS A5.20 classifications E71T-1C, E71T-1M, E71T-9C, and E71T-9M, making it a versatile choice for code-quality work requiring specific impact toughness properties.

This 0.045-inch diameter wire is packaged on a 44-pound fiber spool, suitable for industrial wire feeders. It operates on Direct Current Electrode Positive (DCEP) and offers dual gas flexibility. Operators can utilize 100% CO2 for deep penetration and cost savings, or a mixture of 75% Argon / 25% CO2 for a smoother arc and reduced spatter. The wire formulation ensures low fume generation rates compared to conventional flux-cored wires, contributing to a cleaner workshop environment.

Mechanically, the Excel-Arc 71 provides excellent impact strength at low temperatures (Charpy V-Notch properties down to -20°F or -29°C), satisfying the rigorous demands of structural steel fabrication, shipbuilding, and heavy equipment manufacturing. The slag is self-peeling in most conditions, significantly reducing the labor required for inter-pass cleaning and post-weld finishing. This wire is an ideal solution for shops seeking high deposition rates combined with the ease of use typically associated with premium consumables.
