248000044 - ESAB Dual Shield 7100 Ultra .045" Flux Core Wire, 15kg Spool

High-Performance Gas Shielded Flux Core Wire

The ESAB Dual Shield 7100 Ultra is a premium .045-inch gas-shielded flux core welding wire designed for general purpose and structural steel fabrication. Engineered to meet the rigorous demands of modern industrial applications, this wire distinguishes itself with a highly versatile operating window and superior mechanical properties. It is formulated to perform exceptionally well in all welding positions, making it a go-to solution for complex assemblies where vertical or overhead welding is required without changing consumables.

One of the primary technical advantages of the Dual Shield 7100 Ultra is its flexibility regarding shielding gas. It operates efficiently with either 100% CO2, which is cost-effective for deep penetration, or a 75% Argon / 25% CO2 blend, which typically provides a smoother arc and reduced spatter. This adaptability allows fabrication shops to utilize existing gas supplies without compromising weld quality. Furthermore, the wire is engineered to produce significantly lower welding fumes compared to conventional E71T-1 wires, contributing to a cleaner and safer workshop environment for operators.

The 15kg (33 lb) spool format is standard for industrial wire feeders, ensuring compatibility with a wide range of MIG welding equipment. The wire's formulation ensures low spatter levels and a slag system that is easily removable, often peeling off with minimal effort. This characteristic drastically reduces non-productive time spent on post-weld cleaning and grinding, thereby increasing overall throughput. With Seismic Certification "D" and compliance with AWS A5.20 and CWB W48 standards, the Dual Shield 7100 Ultra is validated for critical applications including bridge construction, ship building, and heavy earth-moving equipment.

In summary, this consumable offers a balanced combination of operator appeal and engineering reliability. Its ability to maintain arc stability across a wide range of parameters helps reduce defects and rework, ensuring high-quality deposits for critical structural connections.
