Copper-coated welding wire SG2
Copper-coated solid electrode wire for MIG/MAG welding. Designed for welding fine-grained carbon-manganese steels, construction steels, etc.
Produced in Poland from European steels using innovative QBA technology. It is distinguished primarily by its excellent purity and appropriately selected geometry. Thanks to these advantages, the consumption of welding accessories is significantly reduced. It performs excellently across the full range of welding parameters, from the lowest to the highest, consistently maintaining arc stability. It is used in industries such as construction, automotive, petrochemical, and in the building of ships, boilers, and containers.
