OVERVIEW

Professional Quality Welds with Hobart HB-28

Take your welding projects to the next level with the Hobart HB-28 .035-inch MIG welding wire. Whether you are tackling automotive body repairs, fixing farm equipment, or creating custom metal art in your garage, this wire is engineered to deliver professional-grade results. The HB-28 is an ER70S-6 class wire, which means it is packed with special cleaning agents that help neutralize impurities. This makes it incredibly forgiving to use on steel that isn't perfectly clean, allowing you to lay down strong, crack-free welds even if there is a bit of rust or mill scale present on the surface.

One of the biggest advantages of the Hobart HB-28 is its smooth performance. Welders everywhere appreciate the stable arc and low spatter this wire produces. Less spatter means you spend less time grinding and chipping away mess after you are done welding, and more time admiring your work. The high-quality copper coating on the wire ensures it feeds smoothly through your welder's gun, preventing the frustration of bird-nesting and jamming that can interrupt your workflow. It is designed to flow wet and smooth, giving you that desirable "stack of dimes" appearance with minimal effort.

This 2-pound spool is the perfect size for portable MIG welders and spool guns. It is lightweight and easy to handle, making it ideal for mobile repair jobs or smaller projects where a large industrial drum would be overkill. You have the flexibility to use it with straight CO2 gas for deep penetration on thicker brackets, or an Argon/CO2 mix for a cleaner, prettier weld on thinner sheet metal. From collision repair to general fabrication, the Hobart HB-28 is the reliable choice for welders who demand consistency and quality in every bead. Upgrade your consumables today and see the difference Hobart quality makes.

FAQ

You can use either 100% CO2 for deeper penetration and economy, or a mix of 75% Argon / 25% CO2 for a smoother arc and less spatter.

Yes, the ER70S-6 classification indicates high levels of deoxidizers (manganese and silicon) which help weld through light to moderate rust and mill scale.

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

This is a 2lb spool, which typically has a 4-inch diameter. It fits most small portable MIG welders and spool guns designed for 4-inch spools.

No, this is a solid MIG wire that requires an external shielding gas.

Yes, the .035 diameter is versatile enough for auto body work, though .023 or .030 is sometimes preferred for extremely thin sheet metal. However, this wire works well for general automotive repairs.

The AWS classification for this wire is ER70S-6.

Yes, the Hobart HB-28 is copper-coated to improve feedability and electrical conductivity.
