S307608-070 - Hobart Quantum Arc 6 ER70S-6 .035" MIG Wire - 950lb Drum

High-Performance ER70S-6 Wire for Automation

The Hobart Quantum Arc 6 is a premium mild steel solid wire formulated to meet the rigorous demands of high-volume industrial manufacturing. Classified as an AWS ER70S-6, this wire is engineered with elevated levels of manganese and silicon deoxidizers. This chemical composition allows the wire to perform exceptionally well on base metals that exhibit light to moderate amounts of rust, mill scale, or oil, ensuring sound welds with minimal porosity even in less-than-ideal surface conditions.

This specific SKU (S307608-070) is supplied in a 950 lb (431 kg) Robo Pak, a bulk packaging solution designed explicitly for robotic and semi-automatic welding cells. The large volume significantly reduces the frequency of wire changeovers compared to standard spools, thereby increasing overall arc-on time and production efficiency. The wire is precision-wound to ensure tangle-free feeding at high wire feed speeds, a critical factor for maintaining the uptime of automated systems.

Quantum Arc 6 is versatile in its shielding gas requirements, operating smoothly with either 100% CO2 or a 75% Argon / 25% CO2 blend. It is suitable for single and multi-pass welding in all positions (depending on the mode of transfer). Its consistent arc characteristics and superior wetting action result in flat, well-washed beads that require minimal post-weld grinding or cleanup. This wire is a staple for industries ranging from automotive frame manufacturing to heavy construction equipment fabrication.
