E71T-GS Welding Wire: Easy, Clean, and Gas-Free Welding

Welding made simple starts with the right wire. E71T-GS is a gasless welding wire designed for clean, hassle-free welds — no shielding gas required. Perfect for mild steel, it delivers a stable arc, deep penetration, and smooth finish, even in outdoor conditions. 

At PGN Bearings, you’ll find a range of spool sizes and diameters to match everything from quick repairs to heavy-duty projects — all with certified quality and consistent performance.

What Is E71T-GS Wire and What Is It Used For?

E71T-GS is a flux-cored welding wire designed for gasless applications. Its AWS (American Welding Society) classification indicates it's suitable for all-position welding on mild steel, offering reliable mechanical strength and performance.

Because it's self-shielded, E71T-GS is ideal for outdoor welding or situations where shielding gas is impractical. Commonly used in maintenance work, light fabrication, and quick repairs, it delivers clean, solid welds with smooth finishes—even on thin-gauge materials.

In short, it’s a practical and dependable choice for welders who need flexibility, strength, and ease of use — whether for DIY tasks or more demanding jobs.

How to Choose the Right E71T-GS Wire?

When selecting the right E71T-GS wire for your job, consider two key factors: wire diameter and spool weight.

The .030" (0.8 mm) wire offers better control and is ideal for thinner materials or more precise welding. The .035" (0.9 mm) wire delivers deeper penetration and higher deposition rates, making it better suited for slightly thicker metals or heavier-duty tasks.

As for spool size, the 2 lbs option is great for quick fixes, home use, or portable applications. The 10 lbs spool is ideal for extended use, higher-volume welding, or professional environments.

Tip: Be sure your welding machine supports self-shielded flux core wire to get the best results.

Key Benefits of E71T-GS Wire

Choosing E71T-GS wire means relying on a welding solution that is easy to use, versatile, and cost-effective. 

Here are the main advantages that make this wire a go-to option for both professionals and DIY welders.

No Shielding Gas Required

As a self-shielded flux core wire, E71T-GS eliminates the need for gas cylinders. Just plug it into a compatible welding machine and you’re ready to start.

Performs Well Outdoors

It’s ideal for outdoor welding—even in windy or open environments—since the flux core protects the arc from external contaminants.

User-Friendly

It offers a stable arc, easy slag removal, and forgiving performance with basic machine settings. Perfect for beginners and experienced welders alike.

Budget-Friendly and Versatile

No need for extra accessories, and suitable for a wide range of applications—from maintenance and light fabrication to general-purpose mild steel welding.

How Many Meters in 1 kg of Wire?

A common question among welders is: how much welding wire do I get per kilogram? The answer depends on the wire diameter, but on average, 1 kg of E71T-GS wire provides around 30 to 40 meters, or 2.2 lbs of wire providing 100 to 130 ft.

Thinner wires like .030" (0.8 mm) offer more length per weight, making them ideal for precision work or lower-volume welds. Slightly thicker wires like .035" (0.9 mm) yield less wire per kg but deliver better penetration and faster deposition rates.

10 lbs spools (about 4.5 kg) are ideal for extended jobs where consistent feed and fewer spool changes are key to productivity.

Understanding wire yield helps you plan ahead, manage your usage, and choose the right product for your welding needs.

FAQ – E71T-GS Welding Wire

1. What does E71T-GS mean?

E71T-GS is a classification from the American Welding Society (AWS) for a flux-cored wire designed for gasless welding in all positions. The "GS" suffix refers to general-purpose use with no shielding gas required.

2. Does E71T-GS wire require shielding gas?

No. E71T-GS is a self-shielded flux core wire, which means it does not require external gas. It's ideal for outdoor or ventilated environments where gas shielding would be difficult.

3. What is the difference between .030" and .035" wire?

.030" (0.8 mm) wire provides more control and is recommended for thin materials. .035" (0.9 mm) wire offers deeper penetration and faster welding speed, ideal for slightly thicker metals.

4. What is the tensile strength of E71T-GS wire?

E71T-GS wire has an average tensile strength of 510 MPa, making it suitable for light structural work, maintenance, and mild steel fabrication.
