Eagle 771FGS Gas Shielded Flux Core Wire | E71T-1M All Position

Eagle 771FGS is recommended for:

General fabrication
Heavy equipment repair
Mining equipment
Earthmoving machinery
Structural steel
Pipe steels
Mild and medium carbon steels
Single-pass and multi-pass welding
Vertical and overhead welding

DC Reverse [+] Polarity

Clean the weld area thoroughly and remove worn or fatigued metal before welding. Where required, use a grinder or Eagle 188 airless gouging electrodes for weld preparation.

Use the lowest effective amperage while maintaining approximately 1/2"–3/4" stick-out. Use a stringer bead technique where maximum strength is required.

Eagle 771FGS is an all-position gas-shielded flux-cored wire engineered for dependable production welding and repair work.

Its fast-freeze puddle improves control in vertical and overhead positions, while the soft, stable arc helps produce smooth welds with minimal spatter. It can be used with either 80/20 Argon/CO₂ or 100% CO₂ shielding gas, giving shops flexibility depending on their setup.

Why Eagle 771FGS

All-position performance — designed for reliable flat, horizontal, vertical and overhead welding.

Excellent arc control — soft, stable arc and fast-freeze puddle help improve operator control.

Versatile shielding gas — runs with 80/20 Argon/CO₂ or 100% CO₂.

Built for production and repair — a strong everyday choice for fabrication, structural work, heavy equipment and maintenance welding.

771FGS or 881FMG — Which One Should You Choose?

Choose 771FGS when you need a dependable, economical all-position flux-core wire for general fabrication, structural work and everyday repair on mild and medium carbon steels.

Step up to 881FMG when the application requires the added toughness of a 1% nickel alloy, particularly for severe-service heavy equipment, mining, earthmoving and higher-stress repair work.

771FGS = general-purpose production and repair
881FMG = premium nickel-alloy option for tougher service
