This 0.9mm (.035") flux core welding wire is designed for reliable, all-position welding without the need for external shielding gas. Packaged in a convenient 11 lb (1kg) spool, it provides excellent penetration and a smooth arc, making it ideal for general fabrication, repairs, and MRO projects on mild and carbon steel.

  • AWS/ASME Certified
  • 0.9mm (.035")
  • Flux-Cored Arc Welding (FCAW)
  • Self-Shielded (No Gas Required)
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

Engineered to meet rigorous AWS A5.20 standards, this flux core wire features a composite cored design with internal fluxing agents. This self-shielding formulation eliminates the need for external shielding gases, making it perfect for outdoor or drafty conditions. The wire produces a stable arc, low spatter, and an easily removable slag, ensuring clean, strong welds on a variety of carbon steel thicknesses. Its chemical composition is carefully controlled to provide excellent mechanical properties and reliable performance in demanding industrial welding environments.

This versatile 0.9mm flux core wire is a go-to consumable for fabricators, welders, and MRO professionals. Its ease of use makes it suitable for both experienced welders and those new to the FCAW process. It excels in single-pass applications on thin to medium gauge materials, such as fabricating steel frames, repairing equipment, welding sheet metal, and completing on-site structural repairs. The 11 lb spool size is convenient for shop use and portable welders, offering a great balance of quantity and manageability.

Specifications

  • Material: Cored Steel Wire with Internal Flux
  • Standards: AWS A5.20 / ASME SFA-5.20 (e.g., E71T-GS, E71T-11)
  • Strength/Tensile: 70,000 psi minimum (Typical for E71T classification)
  • Dimensions: Wire Diameter: 0.9mm (.035"); Spool Weight: 11 LBS (1kg)
  • Finish: Smooth wire for consistent feeding
  • Certifications: AWS/ASME Certified

Applications

  • Fabrication: Welding structural steel components, frames, sheet metal, and supports.
  • MRO (Maintenance, Repair, Operations): On-site repairs of machinery, equipment, and agricultural implements.
  • Construction: Tack welding and joining steel members on job sites, especially in outdoor conditions.
  • Automotive & Hobbyist: Body panel work, chassis repairs, and custom fabrication projects.

Target Users

This product is designed for professional welders, metal fabricators, maintenance technicians, and serious hobbyists who require a reliable, gasless welding solution. It is ideal for projects in construction, manufacturing, and general repair where portability and efficiency are key.

Finish Options

This welding wire comes on a standard industrial spool with a clean, smooth finish to ensure consistent and reliable feeding through MIG welding equipment. The final weld bead has a standard metallic appearance after the protective slag layer is removed.

How to Measure

Welding wire is specified by its classification (e.g., AWS E71T-GS), diameter, and spool weight. Ensure the wire diameter matches the requirements of your welding machine's drive rolls and contact tip for proper operation.

Example: AWS E71T-GS, 0.9mm (.035") Diameter, 11 lb Spool.

Order Checklist

  • Confirm Wire Diameter: 0.9mm (.035")
  • Specify Spool Size: 11 LBS (1kg)
  • Verify AWS Classification (if a specific type is needed)
  • Quantity of spools required
  • Request Mill Test Report (MTR) if required for project compliance
  • Check compatibility with your welding equipment
