AFM71T-1 0.045 Flux Core Welding Wire (E71T-1 Equivalent) – All-Position FCAW Wire for Structural Steel | CO₂ / Mixed Gas Compatible | High Strength, Smooth Arc Performance

Not all flux core wire is built the same.

This one is built to perform when it matters.

The AFM71T-1 Flux Core Wire is designed for welders who demand consistent arc stability, clean slag removal, and strong structural welds—whether you’re in the shop or out in the field. This is a low-hydrogen, all-position wire made for high tensile strength applications, giving you confidence on every pass.

From spray-like transfer to smooth bead appearance, this wire delivers control, especially when you’re pushing production or working on critical welds.

 What You Can Expect

Smooth, stable arc with minimal spatter

• Easy slag removal = faster workflow
• Clean bead profile with professional appearance
• Reliable performance in flat, horizontal, vertical, and overhead positions
• Built for high-strength structural steel applications 

 Best Gas Setup

Runs great on 100% CO₂ (maximum penetration, cost-effective)

• Also performs with 75/25 or 80/20 Argon/CO₂ mixes (smoother arc, cleaner welds)

When This Wire Is the Right Choice for You

Buy this wire if:

✅ You’re doing 

structural or code-type work

This wire meets AWS A5.20 / A5.36 classifications, meaning it’s built for real-world structural demands—not hobby-level welding.

 ✅ You need 

all-position capability

If you’re welding:

Vertical up

• Overhead
• Out-of-position joints

This wire is made to hold a puddle and give you control.

 ✅ You want 

production efficiency

Less spatter. Easier slag removal.

That means:

• Faster weld cycles
• Less cleanup
• More profit per job

✅ You weld 

thicker material

With amperage ranges pushing into the 200–400 amp range, this wire is ideal for:

Heavy plate

• Structural beams
• Fabrication work

✅ You need 

strong, reliable welds

• Tensile strength: 71,000–95,000 psi
• Built for durability, not just appearance

When This Wire Might NOT Be for You

If you’re doing thin sheet metal → go MIG instead

• If you don’t have gas → this is not self-shielded flux core
• If you’re a beginner doing light work → this is more of a professional-grade wire

Matador Insight

This is the type of wire you step into when you’re no longer just “learning”…

 You’re producing.

It’s for welders who want their welds to:

Hold under pressure

• Pass inspection
• Look clean doing it
