AK-ER70S-4 (TIG / MIG)

Standard: 

EN ISO 14341-B: G 49 A Z C G4 

AWS A5.18 ER70S-4

GB/T 8110 ER50-4

Description: AK-ER70S-4 is a CO2 gas shielded welding wire with H11MnSiA disc element and copper-plated surface. The welding wire can be used as shielding gas with CO2 or Ar+CO25%-20%, and the welding process performance is good. Under the small current specification, vertical down welding can be carried out, and the weld strength may be improved when shielded with mixed gas.

Application: Suitable for welding carbon steel, and may also be used for highspeed welding of thin plates and pipes.
