OVERVIEW

Hobart HB-28 .024" MIG Wire - 10lb Spool

Take the frustration out of welding thin sheet metal with the Hobart HB-28 .024" MIG Welding Wire. Designed by Hobart Filler Metals, a trusted leader in the welding industry, this wire is the go-to solution for auto body repair, hobbyist projects, and light fabrication. If you have ever struggled with blowing holes through thin fenders or exhaust tubing, the HB-28 in the 0.024-inch diameter is the answer. It allows for precise heat control on materials as thin as 24 gauge, giving you the confidence to tackle delicate jobs with professional results.

This ER70S-6 classification wire is a "forgiving" consumable. It is loaded with high levels of silicon and manganese, which act as scavengers in the weld puddle to float out impurities. This means if your metal isn't perfectly ground to shiny bright steel—perhaps it has a bit of mill scale or a touch of oil—the HB-28 will still help you lay down a solid, strong bead. The copper coating on the wire isn't just for looks; it ensures the wire slides smoothly through your MIG gun liner and makes excellent electrical contact, providing a consistent, stable arc that doesn't stutter or sputter while you work.

The 10-pound spool size is the perfect balance for serious DIYers and professional shops, offering plenty of runtime without the bulk of industrial drums. It fits most standard MIG welders that accept 8-inch spools. Whether you are using a small 110V machine in your garage or a larger 220V shop welder, this wire performs beautifully with either straight CO2 gas or a C25 (Argon/CO2) mix. With the Hobart HB-28, you get minimal spatter, which means less time grinding and more time welding. It is an essential addition to any welder's arsenal for collision repair, steel casting repairs, and general metalworking.

Key Benefits:

  • Prevents Burn-Through: Small .024" diameter is perfect for thin auto body panels.
  • Welds Dirty Metal: High deoxidizers handle light rust and scale easily.
  • Smooth Arc: Copper coating ensures consistent feeding and stability.
  • Versatile Gas: Works with the gas you likely already have (CO2 or Mix).

FAQ

You can use either 100% CO2 or a mixture of 75% Argon and 25% CO2. The Argon mix will generally produce less spatter and a smoother bead appearance.

This .024" diameter wire is specifically designed for thin metals, ranging from 24 gauge (0.025") to 18 gauge (0.050").

No, the Hobart HB-28 is a solid MIG wire (GMAW) and requires an external shielding gas to protect the weld pool.

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

This is a 10 lb spool. It typically uses a standard 8-inch diameter spool hub, common on many MIG welding machines.

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

Absolutely. The .024" diameter is the industry standard for automotive body work because it minimizes heat input and reduces the risk of burning through thin panels.

This wire is classified as AWS A5.18 ER70S-6.
