Weld Star SG2 (G3Si1) Wire [5kg Spool]

The Weld Star SG2 (G3Si1) 5kg Spool is the professional’s choice for mid sized MIG welding applications. Perfectly sized for D200 (200mm) spool hubs, these reels bridge the gap between hobbyist mini spools and heavy industrial 15kg baskets. This is our signature "Green Wire," manufactured using only virgin raw materials from specialized steel mills to guarantee a cleaner, more consistent weld with minimal spatter.

Whether you are working on structural steel, automotive chassis, or industrial machinery, this wire provides exceptional mechanical properties and impact resistance down to -40ºC. Each spool is precision layer wound, which is vital for maintaining a smooth, snag free wire feed, especially in the compact drive systems found in portable inverter welders.
