Non-copper-coated welding wire SG2
Non-copper-coated solid electrode wire for MIG/MAG welding. Designed for welding fine-grained carbon-manganese and structural steels, etc.
Manufactured in Poland from European steels using innovative QBA technology. It is primarily distinguished by low emissions of harmful fumes and vapors, as well as excellent purity and properly selected geometry. These advantages significantly reduce the wear of welding accessories, and the work environment will be much cleaner and more pleasant. The increased content of Si and Mn compared to TS2 allows for higher alloy strength and greater resistance to surface contamination of welded components. It performs exceptionally well across the full range of welding parameters, from the lowest to the highest, consistently ensuring arc stability.It finds applications in industries such as construction, automotive, petrochemical, shipbuilding, as well as in the production of boilers and containers.
