OVERVIEW

Reliable Performance for Tough Jobs

When you are welding on steel that isn't perfectly clean, you need a wire that forgives. The Hobart Quantum Arc 6 .045" MIG wire is designed exactly for those real-world situations. Whether you are repairing farm implements covered in years of wear, fabricating automotive frames, or working on heavy construction equipment, this ER70S-6 wire cuts through light rust and mill scale to lay down a solid, defect-free bead. It saves you time on prep work and ensures your welds hold up under pressure.

Smooth Feeding, Smooth Welding

Nothing kills productivity like a bird's nest in your wire feeder. Hobart has engineered the Quantum Arc 6 with precision winding and a high-quality copper coating to ensure it feeds smoothly, even at the high speeds required for robotic or heavy manufacturing work. The arc is stable and consistent, producing a flat bead profile that wets out nicely at the toes. This means less grinding and finishing work for you after the hood comes up. The low spatter levels further reduce cleanup time, keeping your nozzles cleaner for longer.

Versatile Applications

This 45lb spool is a workhorse for the shop. It runs great on straight CO2 if you are looking for deep penetration and cost savings, or you can switch to a 75/25 Argon mix for a smoother arc and less spatter on thinner materials. It is the ideal choice for welders tackling everything from railcar repairs to general structural fabrication. If you need a wire that balances high-performance specs with the rugged capability to handle imperfect metal, the Quantum Arc 6 is the tool for the job.

FAQ

This wire can be used with 100% CO2 for deeper penetration or a mixture of 75% Argon / 25% CO2 for a smoother arc and reduced spatter.

Yes, as an ER70S-6 class wire, it contains high levels of deoxidizers (manganese and silicon) that allow it to weld through light to moderate rust and mill scale without porosity.

This product comes on a 45 lb Fiber Spool (Fs), which is lighter than steel reels and easier to dispose of than plastic.

Yes, Quantum Arc 6 is specifically noted for its excellent feedability and consistent arc characteristics, making it ideal for robotic and automatic welding applications.

This specific SKU is for 0.045-inch (1.2mm) diameter wire.

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

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

Standard DCEP (Direct Current Electrode Positive), also known as Reverse Polarity, is required for this wire.
