Copper-free MIG/MAG wire for structural steels
ESAB OK Aristorod 12.50 (AWS ER70S-6) is a copper-free solid wire for welding unalloyed steels. Its patented surface treatment improves arc stability and reduces spatter, and being copper-free it feeds smoothly, ideal for mechanized and robotic welding. This item is 0.90 mm in diameter.
Key advantages
- Copper-free: fewer feeding and contamination problems.
- Stable arc and low spatter, even at high current.
- Tough: 60 J at -40 °C with Ar + 20% CO2.
- Certified quality: ABS, BV, DNV, GL, LR, VdTÜV and CE.
Applications
- Steel structures, construction and general fabrication.
- Pressure vessels and transport equipment.
- Mechanized and robotic welding.
