S307615-073 - Hobart Quantum Arc 6 ER70S-6 Solid MIG Wire .052 300lb Drum

Premium ER70S-6 Solid Wire for Automated Fabrication

The Hobart Quantum Arc 6 is a high-performance mild steel solid wire designed to meet the rigorous demands of industrial manufacturing and robotic automation. Classified as an AWS ER70S-6, this wire is engineered with elevated levels of manganese and silicon deoxidizers. This chemical composition provides exceptional cleaning action, allowing the wire to produce sound, porosity-free welds even on base metals exhibiting light rust, mill scale, or oil. It is an ideal choice for fabrication environments where surface preparation may not always be perfect, ensuring structural integrity without sacrificing production speed.

One of the defining characteristics of the Quantum Arc 6 is its superior feedability. In robotic and semi-automatic applications, wire feeding issues can lead to costly downtime and contact tip burn-back. Hobart has formulated this wire to ensure consistent column strength and a smooth surface finish, facilitating reliable feeding through long conduit liners and complex torch angles often found in automated cells. The wire supports a wide range of wire feed speeds, from moderately slow to very fast, making it versatile for various material thicknesses and joint configurations.

The 300lb Rrp (Robo Pak) packaging is specifically designed to maximize arc-on time by reducing the frequency of spool changes. This bulk packaging format is essential for high-volume production lines, such as automotive frame manufacturing and heavy equipment fabrication. The wire operates effectively with both 100% Carbon Dioxide (CO2) and 75% Argon / 25% CO2 shielding gas mixtures, offering flexibility in arc characteristics and penetration profiles. With its ability to wet out smoothly and create flat bead profiles, the Quantum Arc 6 reduces the need for post-weld grinding, further enhancing operational efficiency.
