Best Welding Wire For MIG: Your Top Questions Answered

Q1: What does “ER70S-6” mean in welding wire?

A1: “ER70S-6” is a classification for solid MIG welding wire. “ER” stands for electrode or rod, “70” indicates a minimum tensile strength of 70,000 pounds per square inch (psi), “S” means it’s a solid wire, and “-6” refers to its chemical composition, specifically high levels of manganese and silicon deoxidizers. These deoxidizers help clean up impurities in the weld pool, resulting in stronger, cleaner welds, especially on mildly contaminated or rusty steel.

Q2: Why is the wire diameter important for MIG welding?

A2: Wire diameter significantly impacts your welding. Smaller diameters like .023″ or .030″ are great for thinner materials (e.g., sheet metal, auto body work) because they produce less heat input and are easier to control. Larger diameters like .035″ or .045″ are better for thicker materials, as they can carry more current, provide deeper penetration, and increase deposition rates. Choosing the right welding wire diameter ensures optimal heat input and bead control for your specific project.

Q3: Do I need shielding gas for ER70S-6 MIG welding wire?

A3: Yes, ER70S-6 is a solid MIG wire and absolutely requires shielding gas. Typically, a mixture of 75% Argon and 25% CO2 (often called C25) is used for short-circuit MIG welding on carbon steel, providing a stable arc and good bead appearance. 100% CO2 can also be used, which offers deeper penetration but can result in more spatter. The shielding gas protects the molten weld pool from atmospheric contamination (oxygen and nitrogen), which would otherwise lead to porosity and weak welds.

Q4: What are “deoxidizers” in welding wire and why are they important?

A4: Deoxidizers, primarily manganese and silicon in ER70S-6 wire, are crucial elements that react with oxygen and other impurities in the molten weld pool. This reaction forms slag, which floats to the surface and is easily removed or gets incorporated into the wire itself. By removing these impurities, deoxidizers prevent porosity and ensure the weld metal is strong, ductile, and free from defects, even when welding on slightly rusty or mill-scale covered steel.

Q5: Can I use ER70S-6 wire for aluminum or stainless steel?

A5: No, ER70S-6 MIG wire is specifically designed for welding carbon steel and mild steel. Using it on aluminum or stainless steel will result in a very weak, brittle, and contaminated weld due to incompatible material compositions. Always choose specific filler metals (e.g., ER4043 or ER5356 for aluminum, ER308L or ER316L for stainless steel) that match the base metal you are welding.

Q6: How do I minimize spatter when using MIG welding wire?

A6: Minimizing spatter with your solid MIG wire involves several factors:
1. Proper voltage and wire speed settings: Too high voltage or too low wire speed can cause excessive spatter.
2. Correct stick-out: Maintain a consistent wire stick-out (distance from contact tip to arc) of about 3/8 to 1/2 inch.
3. Clean base metal: Remove rust, paint, oil, and mill scale.
4. Proper torch angle: A slight push angle (10-15 degrees) generally produces less spatter than a drag angle.
5. Quality shielding gas: Using a higher Argon mix (e.g., 75/25 Argon/CO2) tends to produce less spatter than 100% CO2.
6. Use a quality welding wire: As discussed in our reviews, some wires are formulated to inherently produce less spatter.
