Select 125-K4C

Low Alloy / Flux Cored / Gas Shielded


Features

  • The basic slag system of this electrode provides better mechanical properties and diffusible hydrogen levels in the weld deposit than T-1 (rutile) slag systems.
  • Globular arc transfer, producing more spatter than T-1 slag systems but much improved over usual T-5 types.
  • Slag removal and bead geometry are similar to those of E12018 electrodes.
  • Ideal selection for welding high strength, low alloy steels such as T-1, HY-100, ASTM A514, and others of similar strength. Also use for repair of high strength castings.
  • Designed for 100% CO₂ shielding gas. If you wish to use 75% Ar / 25% CO₂, Select 125-K4M is the preferred product
