S305406-022 - Hobart HB-28 .030" ER70S-6 Mild Steel MIG Wire - 10lb Spool

Versatile .030 MIG Wire for Auto and Farm Repair

Hobart's HB-28 .030-inch MIG Welding Wire (10 lb Spool) is the go-to choice for welders seeking reliability and ease of use across a wide range of mild steel projects. Whether you are repairing agricultural machinery, working on an automotive restoration, or fabricating custom steel brackets, this ER70S-6 wire delivers professional results. The "S-6" classification indicates a high level of deoxidizers (silicon and manganese), which act as cleaning agents during the weld pool freeze. This means you get stronger, cleaner welds even if the steel surface isn't perfectly prepped down to shiny metal.

One of the standout features of the HB-28 is its exceptional arc stability. The copper coating on the wire prevents rust on the spool and ensures the wire slides smoothly through your MIG gun's liner. This smooth feeding translates to a consistent arc, less spatter, and better control over the weld puddle. For thin-gauge sheet metal, such as auto body panels, the .030-inch diameter provides the perfect balance of heat input and deposition, reducing the risk of burn-through while still offering enough fill for slightly thicker sections.

This 10-pound spool is designed to fit most standard MIG welders that accept 8-inch diameter spools. It performs admirably with both straight CO2 gas, which is economical and provides deep penetration, and C25 (75% Argon / 25% CO2), which produces a visually appealing bead with minimal spatter. By choosing Hobart HB-28, you are investing in a wire that offers good wetting properties, meaning the weld metal flows out smoothly to the edges, creating a flat, uniform bead that looks great and holds strong. It is an essential consumable for any workshop handling mild steel and low-alloy steel fabrication.
