Features and Applications

A copper coated solid wire suitable for single pass or multipass welding of unalloyed and low-alloyed carbon-manganese steels.

The higher Si-Mn content increases the weld metal strength and leaves a good bead appearance.

Designed for semi-automatic and full-automatic GMAW applications.

Good mechanical properties at sub-zero temperatures down to -40ºC.

Vacuum-sealed aluminium foil packaging to prevent moisture absorption.

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.

Test Certificates can be found online @wilkinsonstar247.com
