Key Advantages
Engineered for low-to-medium contaminated surfaces, this ER70S-4 wire outperforms standard S2 grade with enhanced cleaning action. Its optimized manganese-silicon composition creates a more fluid puddle and flatter bead profile, reducing post-weld cleanup. High-purity construction eliminates cracks and fusion defects common in inferior wires.
Applications
Ideal for mild steel fabrication, structural welding, automotive repair, and industrial maintenance. Perfect for TIG welding projects where surface preparation is challenging or consistent bead appearance is critical.
Quality Assurance
Every batch undergoes rigorous testing with a certificate of conformance. Each rod features permanent grade identification for traceability. Manufactured to exceed industry standards for reliability and weld integrity.
Why Choose Our ER70S-4?
Unlike generic filler wires, our product offers:
? Higher cleaning capability for contaminated surfaces
? Superior flow characteristics for smoother welds
? Industrial-grade purity reducing defect rates
? Full batch traceability and certification
FAQ
Q: What makes ER70S-4 different from ER70S-2?
A: ER70S-4 contains higher manganese and silicon, providing better cleaning action and more fluid puddle behavior.
Q: Can this wire be used with DC TIG welding?
A: Yes, it is designed for DCEN (Direct Current Electrode Negative) TIG applications on mild steel.
Q: Is pre-cleaning required before welding?
A: While it handles light contaminants, heavy rust or scale should still be removed for optimal results.
