Description
Weld Star – SG2 (G3Si1) Wire (1.2mm) 15kg (Plastic) – Min QTY 2
Weld Star SG2 is a copper-coated solid wire designed specifically for single pass or multipass welding. With its unique composition, this wire exhibits impressive mechanical properties, even at sub-zero temperatures as low as -40°C. Each wire is precision layer wound and comes in a vacuum-sealed plastic bag to prevent moisture absorption, ensuring the highest quality and performance during welding.
Features and Benefits:
- Copper Coated: Ensures smooth and consistent feeding during the welding process.
- Versatile Welding: Suitable for both single pass and multipass welding, providing flexibility in various applications.
- Sub-Zero Performance: Maintains good mechanical properties even at temperatures down to -40°C.
- Precision Layer Wound: Guarantees consistent wire feeding and minimizes the chance of tangling.
- Moisture Protection: Comes in a vacuum-sealed plastic bag to prevent moisture absorption, ensuring optimal welding performance.
- Alignment Hole Clip: Ensures smooth feeding and reduces the risk of wire jams.
- Quality Assurance: Made using virgin raw materials from specialized steel mills, ensuring consistent reliability and quality.
