OVERVIEW

Premium Hobart HB-28 .035" MIG Wire for Professional Results

Elevate your welding projects with the Hobart HB-28 .035" ER70S-6 MIG Welding Wire, available in a convenient 10lb spool. This wire is a favorite among professional welders and serious hobbyists alike for its forgiving nature and superior arc characteristics. If you are working on automotive repairs, building custom trailers, or fabricating steel structures, the HB-28 provides the reliability you need to lay down strong, clean beads every time.

One of the standout features of the HB-28 is its high deoxidizer content. In the real world, metal isn't always perfectly clean. This wire is chemically formulated to handle steel that might have some surface contaminants like rust or mill scale, preventing porosity and ensuring a sound weld. The "wetting" action of the puddle is excellent, meaning the weld metal flows out smoothly to the toes of the weld, creating a flat, professional-looking profile that requires less grinding and finishing. The copper coating on the wire not only protects it from corrosion during storage but also acts as a lubricant for the wire feeder, ensuring a steady wire speed and a stable arc.

This 10lb spool is designed to fit most medium-sized and portable MIG welding machines, making it a great option for mobile welding rigs or garage workshops. It performs beautifully with standard 75/25 Argon/CO2 gas for low spatter and high visual appeal, but it is also fully capable of running on economical 100% CO2 for deeper penetration. As a bonus, Hobart filler metals often qualify as accessories for Miller Electric machine rebates, adding even more value to your purchase. Choose Hobart HB-28 for a frustration-free welding experience that delivers industrial-strength results.

Ideal Applications:

  • Auto Body and Collision Repair
  • Farm and Agriculture Equipment
  • General Metal Fabrication
  • Shaft Build-up and Repair
  • Home Hobbyist Projects

FAQ

Hobart HB-28 is designed to work with both 100% CO2 and Argon/CO2 mixtures (commonly 75% Argon / 25% CO2). The Argon mix typically provides a smoother arc with less spatter, while CO2 offers deeper penetration.

Yes, the ER70S-6 classification indicates high levels of manganese and silicon deoxidizers, making this wire much better suited for welding over light rust, mill scale, and oil compared to ER70S-3 wires.

This is a 10 lb (approx. 4.5 kg) spool. It typically uses a standard 8-inch diameter spool size with a 2-inch arbor hole, fitting most portable and compact MIG welders.

Yes, the .035" diameter is versatile enough for many automotive applications, although for very thin sheet metal (22-24 gauge), a smaller .023" or .030" wire might be easier to control to prevent burn-through.

No, this is a solid wire (GMAW) and requires an external shielding gas cylinder. It does not contain internal flux like flux-cored wires.

Solid MIG wires like the Hobart HB-28 should be welded using DCEP (Direct Current Electrode Positive), also known as Reverse Polarity.

Yes, Hobart filler metals often qualify as an accessory for Miller Electric machine rebates. Please check the specific terms of current rebate offers to confirm eligibility.
