1170S6030 - ER70S-6 Mild Steel Solid MIG Wire, 0.030 Inch, 11 lb Spool

Smooth Running .030" MIG Wire for Every Job

If you are looking for a "do-it-all" wire for your shop, this ER70S-6 .030-inch solid wire is the standard for a reason. Whether you are patching up a car frame, building a welding table, or fixing farm equipment, this wire runs smooth and lays down a bead you can be proud of. The "6" in 70S-6 means it is loaded with cleaners (manganese and silicon) that help float out impurities. This is a huge advantage when you are welding on steel that isn't perfectly shiny. If you can't grind every inch of mill scale or rust off your workpiece, this wire is forgiving enough to still give you a solid, non-porous weld.

The 0.030-inch diameter is the sweet spot for many welders. It is thin enough to handle sheet metal without blowing through instantly, but it has enough body to weld 1/4-inch steel with multiple passes or proper beveling. It runs beautifully on a standard 75/25 Argon/CO2 mix, giving you that classic "bacon frying" sound and a flat, clean bead that requires minimal grinding. If you are on a budget or need maximum penetration, you can also run it on straight CO2. The 11 lb spool is a perfect size—it lasts a long time so you aren't swapping spools every hour, but it keeps your machine light enough to move around the garage or job site.

One of the biggest frustrations in MIG welding is wire feeding issues. This spool is copper-coated and layer-wound to ensure it feeds smoothly through your liner and gun. You won't be fighting against drag or inconsistent arc starts. It wets out nicely at the toes of the weld, making it easier to avoid cold lap, and the puddle is fluid enough to control easily whether you are welding flat, horizontal, or even vertical up. It is a reliable workhorse wire that belongs in every welder's machine.

Why Welders Prefer This Wire:

• Forgiving Arc: Handles imperfect metal preparation better than S-3 wires.
• Great Bead Appearance: Low spatter levels mean less cleanup time with the grinder.
• Perfect Size: The 11 lb spool is the economical choice for serious hobbyists and pros alike.
