Product Overview

Manufacturer: Weld Star

  • Weld star SG2 (G3Si1) MIG welding wire is manufactured using green wire which is produced with virgin raw materials and sourced from specialised steel mills. The results are a consistent quality and reliable MIG welding wire with good welding characteristics.  


    The Endurance bulk wire drum system offers a high productivity solution for continuous high volume welding applications. 

    A copper coated solid wire suitable for single pass and multipass applications.

    Suitable for the welding of unalloyed and low-alloyed carbon-manganese steels.

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

    Precision layer wound for superior wire feeding characteristics

    Typically used on boilers, industrial machinery, bridges, shipbuilding, automotive, rail, structural and engineering fabrications etc.
