Description
Copper Free Steel MIG Wire SIFMIG ZERO SG3 – 1.0 mm (250 Kg POP)
Sifmig Zero SG3 is a high-quality MIG wire that is free from copper coating, ensuring a cleaner deposit and avoiding metallurgical risks associated with increased copper in the weld pool. Manufactured with an uncoppered finish, it offers better feeding, conductivity, and a higher ultimate tensile strength compared to standard SIFMIG SG2.
Features and Benefits:
- Copper-Free: Ensures a cleaner deposit and minimizes metallurgical risks.
- Enhanced Composition: Contains increased manganese and silicon to offer improved mechanical properties.
- High-Quality Finish: Provides better feeding and conductivity.
- Ideal for Automation: Offers arc-stability characteristics and improved feedability, making it perfect for robotic or automated processes.
- Less Cleanup: The absence of copper results in less post-weld cleanup, reducing the need for grinding.
Common Applications:
- General fabrication
- Construction
- Shipbuilding
- Tanks and boilers
- Autobody applications
- Robotic and automated processes
- Welding of mild steels, structural steel, fine-grain steel, pipe steel, boiler steel, and cast steel.
