OVERVIEW

Smooth Arc and Easy Control with Hobart Quantum Arc 6

When you are welding on the job site or in the shop, you need a wire that forgives imperfect conditions and runs smoothly all day long. The Hobart Quantum Arc 6 .045" MIG wire is built for exactly that. This ER70S-6 wire is a workhorse for mild steel applications, known for its ability to handle steel that isn't perfectly clean. Thanks to its extra deoxidizers, you can weld over light rust and mill scale without worrying about porosity or lack of fusion, saving you valuable prep time on non-critical surfaces.

Welders appreciate the Quantum Arc 6 for its stable arc and low spatter levels. A stable arc means you have better control over the puddle, resulting in cleaner, better-looking beads with less post-weld cleanup. The fluid puddle wets out nicely at the edges, reducing the chance of cold lap. Because it is copper-coated and wound on a sturdy 45 lb steel reel, it feeds smoothly through your MIG gun, reducing the frustration of bird-nesting or stuttering wire feed. This smooth feeding is crucial when you are running long beads or working in out-of-position welds where consistency is key.

This wire is versatile enough for a wide range of projects, from automotive frames and farm implements to heavy construction equipment and pipe welding. It runs great on straight CO2 if you need deep penetration and economy, or you can switch to a 75/25 Argon/CO2 mix for a smoother arc and reduced spatter. Whether you are repairing heavy machinery or fabricating structural components, Hobart Quantum Arc 6 gives you the confidence that your welds will hold strong and look professional.

FAQ

This wire is designed to operate with either 100% CO2 or a mixture of 75% Argon and 25% CO2 (C25). C25 typically provides a smoother arc and less spatter.

Yes, as an ER70S-6 class wire, it contains higher levels of manganese and silicon deoxidizers which help it handle light to moderate rust and mill scale better than ER70S-3 wires.

This specific product is 0.045 inches (1.2 mm) in diameter.

This product comes on a 45 lb Steel Reel (Sr).

Yes, Hobart Quantum Arc 6 is noted for excellent feedability and consistent cast/helix, making it an excellent choice for robotic and automatic welding applications.

No, this is a solid MIG wire (GMAW) and requires an external shielding gas.

It is classified as AWS A5.18 ER70S-6.

This wire should be used with Direct Current Electrode Positive (DCEP), also known as Reverse Polarity.
