BLUME® ER70S-4 Datasheet

Q: What shielding gas works best with BLUME® ER70S-4?
A: It performs well with 100% CO₂ or Ar/CO₂ blends, giving you flexibility based on your needs for penetration or bead appearance.

Q: How is BLUME® ER70S-4 different from standard ER70S-4?
A: BLUME® provides better arc stability, stronger penetration, and cleaner welds thanks to optimized deoxidizers and quality control.

Q: Can it handle slightly rusty or dirty steel?
A: Yes – its higher deoxidizer content makes it more forgiving on imperfect base metals compared to ER70S-3.

Q: What industries benefit most from this wire?
A: It’s ideal for fabrication, automotive, agriculture, construction, and industrial repair, where weld integrity and efficiency are essential.
