RAAJMIG-1 (AWS A5.18 ER70S-6)

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

Classification:

AWS/SFA-5.18 : ER70S-6
DIN 8559 : SG2
IS 6419-1971 : Gr-S4

Approvals:

ABS
RDSO (IRS Class I)
BHEL

Characteristics:

Copper coated, double oxidized solid wire for all-position CO₂ welding. Features include smooth and stable arc with low spatter. Thin and uniform copper coating ensures excellent conductivity and allows high-speed feeding with consistent weld quality.

Applications:

Welding structural steel and sheet metal
Carbon steel and low alloy steels
Jobs requiring high finish, precision, and productivity

Shielding Gas:

Welding with CO₂ gas and Ar + CO₂ gas mixture.
