OVERVIEW

Hobart Quantum Arc 3: Premium ER70S-3 MIG Wire

The Hobart Quantum Arc 3 is a high-performance solid MIG welding wire designed to meet the rigorous demands of modern fabrication shops. Classified as an ER70S-3, this wire is engineered with a precise balance of silicon and manganese deoxidizers. While it contains slightly less deoxidizer than an ER70S-6, it is perfectly suited for welding on clean or light-mill-scale steel, making it a favorite in the automotive and general manufacturing industries. The 0.035-inch diameter is versatile enough for thin sheet metal as well as medium-thickness structural components.

One of the standout features of the Quantum Arc 3 is its exceptional feedability. The wire is copper-coated, which not only improves electrical conductivity at the contact tip but also reduces friction within the liner. This results in a stable arc and consistent wire feeding, even at the high speeds often required in robotic or automated welding cells. The 45 lb steel reel provides a substantial supply of material, reducing downtime associated with frequent spool changes in high-volume production environments.

Welders using Hobart Quantum Arc 3 can expect a smooth, stable arc with minimal spatter, which translates to less post-weld cleanup and higher productivity. It performs reliably with both 100% CO2 and Argon/CO2 shielding gas blends, offering flexibility depending on the specific joint requirements and desired penetration profile. Whether you are fabricating metal furniture, storage bins, or automotive frames, this wire delivers the quality and consistency professionals trust.

Key Applications

  • Automotive frames and exhaust systems

FAQ

Hobart Quantum Arc 3 is classified as an ER70S-3 solid carbon steel electrode.

This wire is designed to operate with 100% CO2 or a mixture of 75% Argon and 25% CO2 (C25).

ER70S-3 wires like Quantum Arc 3 can handle light mill scale and rust, but for heavily rusted or dirty steel, an ER70S-6 wire might be a better choice due to higher deoxidizer content.

This product is 0.035 inches (0.9 mm) in diameter.

It comes on a 45 lb (approx. 20 kg) steel reel.

Yes, Hobart Quantum Arc 3 features a copper coating to improve electrical conductivity and feedability.

Yes, its consistent diameter and excellent feedability make it ideal for robotic and automatic welding applications.
