SM70 Mild Steel

MIG Wire Mild Steel

ER70S-6 AWS A 5.18

  Applications

MIG welding of mild & low alloy steels in all positions. Used for general fabrication, structural materials and maintenance.

  Usage Specifications

ER70S-6 is a copper coated solid wire designed for all position welding by short-circuiting type transfer. As the deposition efficiency is high and penetration is deep, highly efficient welding can be performed. It is supplied on 5 & 15 kg Precision Layer Wound Spools, or 250 - 300 Kg bulk Max-Pac’s.
