ESAB ARISTO ROD 12.50 1.2MM BP 250KG
ESAB Aristo Rod 12.50 1.2mm MIG Welding Wire – Ballpac 250kg
Product Overview
The ESAB Aristo Rod 12.50 1.2mm Ballpac 250kg is a premium copper-free, manganese-silicon alloyed solid MIG welding wire engineered for GMAW (Gas Metal Arc Welding) of unalloyed and fine-grained carbon-manganese steels. Classified as an ER70S-6 / G3Si1 equivalent wire, it's the trusted choice for structural fabrication, shipbuilding, pressure vessel manufacturing, automotive components, and heavy equipment welding where consistent, high-quality welds are non-negotiable.
Supplied in ESAB's large-format 250kg Ballpac, this pack size is purpose-built for high-volume, continuous production welding — minimizing downtime from frequent spool changes and maximizing productivity on both manual and mechanised/robotic welding lines.
Key Features
- ASC (Advanced Surface Characteristics) Technology – ESAB's proprietary surface treatment improves wire feedability, enhances arc starting, and extends contact tip life
- Copper-Free Coating – Reduces copper flaking in the liner and contact tip, minimizing feed interruptions and contact tip wear
- Stable, Low-Spatter Arc – Delivers a smooth, consistent arc even at high welding currents, reducing post-weld cleanup and rework
- Superior Feedability – Trouble-free wire feeding at high wire speeds and over long feed distances, ideal for robotic and mechanised welding cells
- Excellent Wetting Action – Balanced manganese and silicon content produces a fluid weld pool, allowing effective welding over light to moderate mill scale and rust
- Low Fume Emission – Cleaner working environment and reduced operator exposure
- 250kg Ballpac Format – Compact, high-capacity bulk packaging designed to reduce changeover downtime in production environments
