StarBlaze Prime ER70S6

StarBlaze Prime ER70S-6 Copper-Free wire is a revolutionary, eco-friendly solid carbon steel MIG welding wire designed for high-performance fabrication. Unlike standard carbon steel wires, this premium variant completely eliminates the exterior copper coating, replacing it with a proprietary Nanograph-R coating to protect against rust while ensuring exceptional arc performance.

Core Product Features
“StarBlaze Copper-Free ER70S-6 Welding Wire is engineered to help reduce copper contamination, maintain cleaner wire feed systems, and lower maintenance requirements.”
Flake-Free Feedability: Eliminating the copper layer prevents mechanical copper flaking inside drive rolls, liners, and contact tips, drastically cutting machine maintenance downtime.
No Copper Contamination: Removes the risk of copper inclusion in the weld pool, preventing hot cracking or contamination in specialized chemical or nuclear infrastructure.
Stable Arc & Low Spatter: The advanced Nanograph-R surface coating provides super-smooth wire feeding, effortless re-striking, and an exceptionally stable arc.
Green Manufacturing: Manufactured utilizing clean, eco-friendly green technology, making it safer for the environment and reducing toxic copper fumes in the workshop.
