AWS A5.18 ER80S-G MIG Welding Wire is a solid wire for butt or fillet MAG welding of mild steel and 590N/mm2 grade steel. It also can be operated with a wider range of welding currents than other solid CO2 wires. It is suitable for welding high tensile strength steel used in construction welding, vehicles and bridges.

Characteristics and Application
Typical chemical Composition of Weld Metal (%)
Notes on usage:
1.E.S.O. (Electrode Stick Out) must be kept between 15-25mm.
2.Proper welding conditions must be adopted according to the purpose as the bead appearance and penetration are both varied widely.
3. Use 100% Co2 or Ar + Co2 gas mixture as shielding gas.
4. Control within the optimal range of welding conditions for this wire as possible.
