Arcflow 70S-6 Carbon Steel Filler Wire (ER70S-6) is a premium welding consumable developed for welding mild steel and carbon steel components in fabrication, automotive, construction, and general manufacturing industries. The wire conforms to AWS A5.18 ER70S-6 classification, ensuring consistent weld quality and reliable performance in various welding environments.
This filler wire contains higher levels of manganese and silicon, which act as deoxidizers to remove impurities during welding. These elements help produce clean weld deposits even when welding on surfaces with light rust, scale, or oil contamination.
Arcflow ER70S-6 filler wire delivers smooth arc stability, excellent weld bead fluidity, and minimal spatter, enabling welders to achieve strong and visually clean weld joints. The weld metal typically provides a minimum tensile strength of around 70,000 psi, ensuring durability and structural reliability for demanding applications.
The wire is compatible with MIG (GMAW) and TIG (GTAW) welding processes and can be used with shielding gases such as CO₂ or Argon-CO₂ mixtures, making it suitable for both manual and automated welding operations.
Arcflow 70S-6 carbon steel filler wire is widely used in structural steel fabrication, automotive manufacturing, pipelines, tanks, agricultural equipment, and industrial machinery, where high weld strength and productivity are required.
