Weld Star SG2 (G3Si1) Wire [1kg Spool]

Don not compromise on weld quality just because you are using a portable machine. The Weld Star SG2 (G3Si1) 1kg Mini-Spool brings industrial grade "Green Wire" technology to the hobbyist and mobile professional. This copper coated solid wire is produced using premium virgin raw materials, ensuring the same consistent reliability and X-ray quality results as our large scale industrial spools.

Designed to fit standard D100 (100mm) spool hubs, these 1kg reels are perfect for small inverter MIG welders used in automotive bodywork, home workshops, and on site maintenance. Despite its compact size, the wire is precision layer wound to prevent tangles and bird nesting, which is crucial for the smaller drive rolls found on portable machines. Whether you are patching a classic car chassis or fabricating a garden gate, Weld Star SG2 provides a stable arc and a clean finish.
