CHARACTERISTICS :
"Premier" MIG wires are copper
coated solid steel wires suitable for continuous welding
for continuous welding for 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 Random/ Layer Wound wire gives
uniform and sound weld metal deposit.
APPLICATIONS:
Mild and structral steel with Tensile Strength up to 55
kg/mm2
