Product Description:
ER70S-6 is a solid mild steel MIG welding wire designed for welding carbon steel in automotive, structural, and general fabrication applications. Known for its higher silicon and manganese content, it provides strong weld penetration and improved performance on steel with light rust, mill scale, or surface contamination.
In collision repair workflows, it’s commonly used for MIG welding on steel body panels, reinforcements, and structural components. For Canadian collision repair shops, ER70S-6 is a go-to wire for consistent weld quality, good wetting action, and reduced prep time in professional shop environments.
Key Features:
- High manganese and silicon content improves weld quality on contaminated steel
- Excellent arc stability and wetting for smooth, consistent weld beads
- Suitable for MIG welding with CO₂ or Argon/CO₂ shielding gas
- Strong mechanical properties with typical tensile strength around 70,000–80,000 PSI
- Copper-coated surface helps resist corrosion and improves wire feedability
- Available in multiple diameters (.023–.045) for different thickness applications
Ideal For:
- Collision repair technicians performing MIG welding on steel panels
- Body shops across Canada working on structural and non-structural steel repairs
- General fabrication and mechanical shop welding
- Professional shop environments requiring consistent, repeatable weld results
Common Questions:
Q: What is ER70S-6 wire used for?
A: It’s used for MIG welding mild and carbon steel, especially in automotive repair and fabrication.
Q: Why choose ER70S-6 over other MIG wires?
A: Its higher deoxidizer content allows better performance on dirty or lightly rusted steel.
Q: What gas should be used with ER70S-6?
A: It typically runs with CO₂ or a 75/25 Argon/CO₂ mix, depending on the application.
