AWS A5.18 ER70S-G MIG Welding Wire is a solid wire for butt or fillet MAG welding of mild steel and 490N/mm2 grade high tensile steel. Due to the pick-up of Ti, The refinement of traveling spheroidal structure can be obtained. The arc is stable. Deep penetration and well spread at high current range TM-58 provides higher deposition efficiency in welding of thick plate. It features less fume generation and smooth bead appearance. It is suitable for welding vehicles, bridges, industrial machinery and buildings.

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.
