AWS A5.18 ER70S-6 MIG welding wire is a solid wire for butt or fillet MAG welding of mild steel and 490N/mm2 high tensile steel. Stable wire feeding is due to special wire surface treatment. Low spatter loss, stable arc and high deposition efficiency can be obtained. It is suitable for the welding of vehicles, ships, containers and industrial machinery.

Welding Positions:

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.
