Ventajas del producto

  • Improved Welding Stability: The surface coating of copper-free welding wire contains active ingredients that improve arc stability, refine molten droplets, and reduce spatter. Special treatment achieves spatter control and arc stability.
  • Enhanced Corrosion Resistance: Some copper-free welding wire surface treatment technologies combine rust prevention and corrosion resistance, extending the wire’s storage life, especially in humid environments.
  • Wide Applicability: Copper-free welding wire exhibits good adaptability in CO2 gas shielded welding and mixed gas shielded welding (such as Ar+CO2), and is suitable for welding various steels (such as Q345B, low-carbon steel, etc.).
  • Operational Safety: Copper-free welding wire does not contain a copper layer, so it does not produce copper fumes or harmful gases during welding, reducing health threats to operators, and is especially suitable for enclosed or poorly ventilated working environments.
