ER70S-6 0.035 in Carbon-Steel Welding Wire 10 lb - Reliable Feed

In this review the Hobart ER70S-6 0.035 in 10-pound spool is evaluated as a straightforward, workmanlike solid welding wire for general shop and field use. The bottom line: this spool is best for fabricators and contractors who need consistent feeding and clean, porosity-free welds with common shielding gases. The review focuses on performance with rusty or poorly fit plates, spool handling, and value, drawing on product details and customer feedback to explain why this wire is a dependable choice for construction, farm repair, and general maintenance work.

Key Features

• Wire diameter: The 0.035 in wire size provides a balance of penetration and control for medium-gauge sheet and plate work under MIG setups.
• Weld chemistry: ER70S-6 formulation includes powerful deoxidizers that help produce sound, porosity-free welds on mildly dirty or rusty surfaces.
• Spool weight: The 10-pound spool gives enough wire for multiple jobs before a changeover, reducing downtime on shop tasks.
• Feeding performance: Customers report consistent feeding accuracy, which reduces birdnesting and improves throughput when running standard feeders.
• Versatile applications: Recommended for construction, farm implement fabrication, shaft buildup, tanks and truck bodies where fit-up may be imperfect.
• Origin and packaging: Packaged as a single unit with compact package dimensions and manufactured in Taiwan.

Who It's For

This wire is aimed at professionals and serious hobbyists who need a durable carbon-steel filler for everyday MIG work. It suits contractors doing farm implement repair, bodywork on trucks, and welders building steel structures where conditions are not always pristine.

It is less suitable for ultra-high-precision shop work that demands specialty alloys or very large production runs where 50 lb spools are preferred; buyers needing a metal spool rather than a plastic one may also want to look elsewhere.

Pros & Cons

Pros

• Good weld quality with deoxidizers that reduce porosity on marginal surfaces.
• Consistent feeding performance that minimizes stoppages and improves productivity.
• Solid value for money for a 10-pound spool used across a range of shop and field tasks.
• Appropriate 0.035 in diameter for common fabrication and repair work.

Cons

• Plastic spool construction has received mixed reviews and can arrive damaged in some cases.
• Not intended for specialized alloy welding or very large production spools.

Specifications

Our Verdict

The ER70S-6 0.035 in 10-pound spool is a practical choice for welders who prioritize consistent feeding and reliable weld chemistry on everyday jobs. It delivers solid value for farm, construction and general shop use, though buyers who need a metal spool or specialized wire should consider alternatives.

Frequently Asked Questions

Is this wire suitable for rusty or dirty metal?
Yes, the ER70S-6 chemistry includes deoxidizers that help produce sound welds on mildly rusty or oily plates.

What shielding gas should be used?
Use the common MIG shielding gases recommended for ER70S-6, such as argon/CO2 mixtures, for best results.

Does the spool come in metal?
The product ships on a plastic spool and customers have reported some instances of damaged plastic spools, so those needing metal spools should seek other options.
