CHARACTERISTICS :
"Premier" MIG wires are copper
coated solid steel wires suitable for continuous welding
fr general purpose fabrication on low to medium carbon
steels. These wires are manufactured by wet drawing and
special coppering process ensuring longer shelf life,
easy feed and current pickup. The wire gives uniform and
sound weld metal deposit.
APPLICATIONS:
Mild and structural steel with Tensile Strength up to 55
kg/mm2
