Features
- Trouble-free feeding at high wire speeds and lengthy feed distances enabled by ESAB’s Advanced Surface Characteristics (ASC) Technology.
- Excellent start properties and very stable arc at high welding currents with extremely low spatter levels.
- Minimal fume emission, reduced contact tip wear, and improved corrosion protection.
- Unique octagonal Marathon Pac® packaging for efficient handling, easy disposal, and maximized productivity in mechanized and robotic welding.
- Manganese-silicon alloyed solid wire (G3Si1/ER70S-6) for GMAW of unalloyed carbon-manganese steels.
- Compatible with both pure CO₂ and mixed gas shielding (M20, M21, C1) and suitable for high-current welding applications.
