Weld Star – CF2 Copperless (G3Si1) Wire 1.0mm – 18KG
Features and Applications
A non-copper coated solid wire suitable for single pass or multipass welding of unalloyed and low-alloyed carbon-manganese steels.
Environmentally friendly when compared against traditional copper wires offering less fume and smoke in the working environment.
Advantages of a stable arc when working with increased welding speeds that achieves high quality welds with almost no spatter.
Good mechanical properties at sub-zero temperatures down to -40ºC.
Vacuum-sealed plastic bag packaging to prevent moisture absorption.
Fitted with alignment hole clip to ensure smooth feeding.
Precision layer wound for superior wire feeding characteristics.
Typically used on boilers, industrial machinery, bridges, shipbuilding, automotive, rail, structural and engineering fabrications etc.
Green wire is produced using virgin raw materials sourced from specialised steel mills, which ensures consistent reliability and quality.
