Take your welding projects to the next level with the Hobart Quantum Arc 3, a high-performance ER70S-3 solid MIG wire available now at Welders Supply. This 45-pound spool of 0.045-inch wire is the professional's choice for working with clean mild steel. If you are welding new steel, sheet metal, or automotive parts where the metal is free of heavy rust and mill scale, this wire offers distinct advantages over standard S-6 wires. The secret lies in its chemistry; with optimized deoxidizers, Quantum Arc 3 produces a clean weld puddle that freezes fast and leaves behind very few silica islands.
Why does this matter? Silica islands—those glassy deposits often found on top of MIG welds—can be a pain to remove before painting or coating. By reducing these deposits, the Quantum Arc 3 saves you time on cleanup and grinding, allowing you to move parts to the finishing stage faster. This makes it an incredible asset for production lines, auto body work, and manufacturing of appliances or metal furniture. The wire flows smoothly, creating a flat, aesthetically pleasing bead that looks great even before you touch it with a grinder.
Hobart is known for quality, and the Quantum Arc 3 delivers with excellent feedability. The high-quality copper coating ensures the wire glides through your MIG gun liner without snagging, reducing bird-nesting and contact tip burn-back. Whether you are running a manual MIG setup or a semi-automatic system, you will appreciate the stable arc and low spatter this wire provides. It runs well on both straight CO2 for deeper penetration and economy, or C25 (75% Argon / 25% CO2) for a smoother arc and reduced spatter.
Packaged on a 45-pound fiber spool, this product offers a substantial amount of material for long production runs while being lighter on environmental impact when it comes time to discard the empty spool. Trust Hobart Quantum Arc 3 for consistent, high-quality welds on your most critical clean-steel projects. Order yours today from Welders Supply and experience the difference a specialized ER70S-3 wire can make in your shop's efficiency.
