Weld Star - SG2|G3Si1 Wire (1.2mm) 15kg (Basket)
( Available with free of charge UK mainland delivery)
Highlights
A copper coated solid wire suitable for single pass or multipass welding of unalloyed and low-alloyed carbon-manganese steels.
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.
Test Certificates available
