RAAJMIG-90G (AWS A5.28 ER90S-G)

Copper Coated Continuous or Cut Length Solid Wire for TIG/MIG Welding

Classification:

AWS/SFA-5.28 : ER90S-G

Characteristics:

Copper coated solid wire for all-position welding. Provides smooth and stable arc with low spatter. Thin and uniform copper coating ensures excellent conductivity, making it especially suitable for high-speed feeding and consistent weld quality.

Applications:

Welding structural steels with UTS up to 640 N/mm²

Shielding Gas:

MIG welding with CO₂ gas and Ar + CO₂ gas mixture.
TIG welding with Argon gas.
