S307612-033 - Hobart Quantum Arc ER70S-6 .045 MIG Welding Wire

Industrial Grade Mild Steel MIG Wire

The Hobart Quantum Arc ER70S-6 .045" MIG Wire is a premium mild steel solid wire designed for general fabrication and high-production environments. Engineered with higher levels of manganese and silicon deoxidizers, this wire excels in applications where the base material may have light rust, oil, or mill scale. This chemical composition ensures sound welds with minimal porosity, even when surface preparation is not perfect, making it a staple for industrial manufacturing and structural work.

This wire is formulated to operate smoothly with both 100% Carbon Dioxide (CO2) and 75% Argon / 25% CO2 shielding gas mixtures. The versatility in gas selection allows fabricators to balance cost and arc performance based on their specific project requirements. The Quantum Arc series is known for its consistency, providing a stable arc that reduces spatter and post-weld cleanup time. It is particularly well-suited for single and multiple pass applications on carbon steel.

Designed for versatility, the S307612-033 wire supports a wide range of wire feed speeds, from moderately slow manual runs to very fast robotic applications. Its consistent diameter and cast ensure reliable feeding through long conduit runs, which is critical for automated systems to prevent downtime. Whether used for automotive frames, pressure vessels, or heavy farm implements, this ER70S-6 wire delivers the mechanical properties and reliability demanded by professional welders.
