AK-ER70S-3 (TIG / MIG)

Standard: 

EN ISO 14341-A: G 42 4 M 2 Si 

AWS A5.18 ER70S-3

GB/T 8110 ER50-3

Description: AK-ER70S-3 is a CO2 gas shielded welding wire with H10MnSiA disc element and copper-plated surface. The welding wire can be used as shielding gas with CO2 or Ar-CO2, and the welding process performance is good. Small diameter wire can be used for all-position welding with short- circuit transitions. It should be noted, however, that the use of CO2 shielding gas combined with excessive heat input may result in lower weld strength than specified.

Application: Suitable for welding low-carbon steel and low-alloy steel structures.
