MIG WELD SG3 Wire 1.2mm /15kg JQ MG50-6A GOLDEN BRIDGE (G4Si1) BS300

MIG WELD SG3 Wire 1.2 mm / 15 kg JQ MG50-6A GOLDEN BRIDGE (G4Si1) BS300

MIG WELD SG3 JQ MG50-6A wire from GOLDEN BRIDGE is a copper-coated solid welding wire designed for MAG welding of non-alloy and low-alloy structural steels. It corresponds to classification SG3 / G4Si1 / ER70S-6. Thanks to the increased manganese and silicon content, it provides excellent deoxidising properties, a stable welding arc, and high-quality weld metal with high strength and toughness.

The wire is characterised by low spatter formation, good feeding properties, and a uniform weld bead appearance. According to the manufacturer, it has a good tolerance to scale and slight surface contamination of the base material, as well as low sensitivity to porosity. It is suitable for welding in all common welding positions using CO2 (C1) or an Ar/CO2 mixture (M21) as a shielding gas. The copper-coated surface ensures reliable electrical contact and smooth wire feeding.

The wire is suitable for welding structural, fine-grained and selected low-alloy steels with a strength class of approximately 500 MPa. It is used in the production of steel structures, bridges, frames, machine components, transport equipment, trailers, tanks and industrial equipment. The 1.2 mm diameter provides a higher deposition rate and is suitable for the regular welding of medium to heavy-duty steel components. The 15 kg BS300 spool is designed for professional welding workshops, metal fabrication, and industrial operations.
