AK-ER60A
Standard:
EN ISO ——
AWS A5.28 ER80S-G
GB/T 8110 ER55-G
Characteristics and Applications: AK-ER60A is low alloy steel copper-plated gas shielded wire, wire melting speed, arc stability, small spatter, beautiful weld shape, weld metal has good mechanical properties. Suitable for welding of 550 ~ 600MPa steel structure. Commonly used in hydropower, bridges, petrochemical, engineering machinery, coal mining machinery and other structures of the welding.
Note:
1. The protective gas is rich argon gas with a flow rate of 15-20L/min.
2. The impurities such as water, oil and embroidery must be removed from the welding area.
3. When the current is more than 250A, the wire dry elongation should be 20-25mm
