Features
- Bare manganese-silicon alloyed solid wire for Gas Metal Arc Welding (GMAW) of unalloyed and fine-grained carbon-manganese steels
- Non-copper-coated formulation reduces fume emission, lowers spatter levels, and enhances corrosion resistance
- Advanced Surface Characteristics (ASC) Technology ensures smooth, trouble-free feeding at high wire speeds and long cable runs
- Esab Octagonal Marathon Pac® 5 kg spool delivers efficient handling, easy disposal, and minimal scrap for mechanized and robotic welding
- Compatible with pure CO₂ or argon/CO₂ shielding gases (C1, M20, M21 per EN ISO 14175)
- Minimum yield strength of 420 MPa with typical tensile strengths up to 586 MPa depending on shielding gas
- Excellent arc stability at high currents with reduced contact tip wear and superior start properties
- 0.8 mm diameter wire on a 5 kg spool (SKU 1A50084600) for precise, high-productivity welding
