Description
Weld Star – CF2 (G3Si1) Wire (1.0mm) 18kg
Weld Star CF2 (G3Si1) is a non-copper coated solid wire designed for welding unalloyed and low-alloyed carbon-manganese steels. This wire is precision layer wound for superior feeding and is vacuum-sealed in a plastic bag to prevent moisture absorption. It is produced using virgin raw materials from specialized steel mills, ensuring consistent reliability and quality.
Features & Benefits:
- Non-Copper Coated: Reduces environmental impact and provides a cleaner working environment.
- Stable Arc: Allows for increased welding speeds and produces high-quality welds with minimal spatter.
- Cold Resistant: Offers good mechanical properties even at sub-zero temperatures down to -40°C.
- Precision Layer Wound: Ensures superior wire feeding during the welding process.
- Environmentally Friendly: Emits less fume and smoke, providing a cleaner working environment.
Common Applications:
- Boilers
- Industrial machinery
- Bridges
- Shipbuilding
- Automotive
- Rail
- Structural and engineering fabrications.
