Comprehensive FAQ: Choosing the Best Welding Wire Brands

What is the difference between ER70S-6 and E71T-GS welding wire?

The core difference lies in their shielding method and composition. E71T-GS is a flux core wire (FCAW) that is self-shielding (gasless). It’s primarily used for single-pass welds, often in portable or outdoor environments. ER70S-6 is a solid MIG wire (GMAW) that requires an external shielding gas (like Argon/CO2 mix). It produces much cleaner welds, has minimal spatter, and is used for multi-pass structural work where strength and appearance are crucial.

Should I choose .030 or .035 diameter wire?

Choosing the diameter depends on the thickness of the metal you are welding and your machine’s capacity. .030 welding wire is generally more versatile and easier to use on thinner sheet metal (like 16 gauge), as it requires less heat and minimizes burn-through. .035 welding wire is better suited for welding materials 1/8 inch thick and above, providing greater penetration and higher deposition rates.

What does “DCEN” mean and why is it important for some welding wire?

DCEN stands for Direct Current Electrode Negative. This polarity setup is required by some specific flux core wires, such as the Blue Demon E71T-11. When using DCEN, the wire (electrode) is negative, which tends to concentrate the heat in the base metal, resulting in deeper penetration—ideal for structural welds and multi-pass operations. Standard solid MIG wire typically uses DCEP (Direct Current Electrode Positive).

Why do solid wires like ER70S-6 need high levels of Silicon and Manganese?

These elements act as powerful deoxidizers. When welding, contaminants like mill scale or rust can introduce oxygen into the weld pool, leading to porosity (holes or bubbles). High levels of Silicon and Manganese react with these impurities, cleaning the weld pool and ensuring a porosity-free, high-quality bead. This is especially important when reviewing the best welding wire brands for professional use.

Are flux core wires truly as strong as solid MIG wires?

Generally, high-quality solid MIG wires (like ER70S-6) used with gas produce welds that meet higher tensile and yield strength requirements and offer better impact properties than general-purpose flux core wires (like E71T-GS). While specialized flux core wires (like E71T-11) can achieve structural strength suitable for multi-pass applications, solid wire is the standard for high-specification, code-compliant structural welding.

What are the benefits of using an ABS plastic spool instead of a metal spool?

Many of the top best welding wire brands now use high-quality ABS plastic spools, especially for smaller 2lb sizes. ABS spools are lighter, less prone to damage during shipping, and, most importantly, they prevent issues like rust contamination from the spool material potentially fouling the weld wire itself, ensuring better feedability.
