AK-ER49-1 (TIG / MIG)

Standard： 

EN ISO 14341-B: G 49 A 3 C G7

AWS A5.18 ER70S-7

GB/T 8110 ER49-1

Description: AK-ER49-1 is a CO2 gas shielded welding wire with H08Mn2SiA disc element and copper- plated surface. The welding wire can be welded with a large current, with less spatter and good anti- porosity. Also available for all-position welding of short-circuit transitions.

Application: Suitable for welding low carbon steel and some low alloy steel structures.It can be used to weld thin plates that require a smooth bead and steels with less severe rust and oxidation
