ESAB ARISTO ROD 12.50 1.0MM SPOOL 18KG

Premium Copper-Free MIG Wire for High-Performance Steel Welding

The ESAB OK AristoRod 12.50 is a bare Mn-Si-alloyed G3Si1/ER70S-6 solid wire designed for GMAW (MIG) welding of non-alloyed steels, making it ideal for general construction, automotive components, pressure vessel fabrication, and shipbuilding. Supplied on an 18kg spool in a precise 1.0mm diameter, this wire delivers consistent, professional-grade results for both manual and automated welding applications.

Advanced Surface Characteristics (ASC) Technology

This wire is treated with ESAB's unique Advanced Surface Characteristics (ASC) technology, taking MAG welding operations to new levels of performance and overall efficiency, especially in robotic and mechanised welding. Unlike traditional copper-coated wires, the ASC surface treatment eliminates the risk of copper flaking, which is a common cause of liner clogs and contact tip contamination — keeping your welding equipment running cleaner for longer.

Key Features & Benefits

• Superior Feedability – Trouble-free feeding at high wire speeds and lengthy feed distances, even in demanding robotic and mechanised setups.
• Stable Arc Performance – Delivers a very stable arc at high welding currents with extremely low spatter levels.
• Excellent Weld Puddle Control – Contains balanced levels of manganese and silicon to provide a fluid weld puddle with superb wetting action.
• Rust & Mill Scale Tolerant – The manganese and silicon content also makes this wire a strong choice for welding over moderate to high levels of rust and mill scale.
• Reduced Maintenance – Reduced contact tip wear and improved corrosion protection extend the life of your consumables.
• Cleaner Operation – Low fume emission and excellent start properties for a smoother, safer welding experience.

Shielding Gas Compatibility

Compatible with 100% CO2, argon/CO2 mixtures, argon/O2 mixtures, and other argon-based mixed gas blends, giving you flexibility to match the gas to your specific application and desired weld characteristics.

Applications

Ideal for welding carbon steels typically used in structural work, automotive manufacturing, agricultural and heavy equipment, and general fabrication, as well as pressure vessel fabrication and shipbuilding.

Specifications

Best For: Fabricators, structural steel welders, automotive shops, and mechanised/robotic welding cells looking for a reliable, high-feedability wire that reduces downtime and spatter.
