Description
MIG Welding Wire (AWS: ER70S-6)
MARUTHI MIG Welding wire (AWS: ER70S-6) is a copper coated gas metal arc welding wire in 15 kg spools. Ideally designed for semiautomatic and full automatic GMAW applications. Working temperature can range between -50 to 450 ̊ C. CO2 or 80% Ar-20 % CO2 are used for gas shielding.
