Select 125-K4M

Carbon Steel / Flux Cored / Gas Shielded


Features

  • Designed for welding of low alloy steels, such as ASTM A514 or HY-100. Also well suited for structural welding and general fabrication.
  • Basic slag system allows for excellent mechanical properties.
  • In contrast with T-1 slag systems, this electrode has a globular transfer. However, the welding performance is improved over usual T-5 slag systems, featuring excellent slag release and bead geometry.
  • Typical applications include mining machinery, cranes, and construction equipment.
  • Designed for 75-80% Ar / balance CO₂ shielding gas. If you wish to use 100% CO₂, Select 125-K4C is the preferred choice
