Copper - Coated Continuous solid wire for MIG/MAG welding
Classification   AWS/SFA 5.28
ER 90S-D2
Characteristics  
A copper coated MIG wire for MIG/MAG welding of high tensile steels. Uniform copper coating,smooth
feeding, stable arc and minimum spatter under optimum welding conditions. Normally recommended
with Ar/O2 Shielding,CO2 shielding can also be used.
Approvals   RDSO : Class III
Applications  
Welding of SAILMA 450/450H1 steel used in CONCOR wagons is typical application for this wire. Is
used for welding of high tensile steels like IS 8500 Grades 540 B, 570 B and 590B;IS 2002 Gr. III,IS 1875
