FEATURES & APPLICATIONS

For joining and repairing boiler plate, pipe steels, shipbuilding steels and cast steels. Excellent for weathering steels, such as “Corten”.

  • Extra low hydrogen – Moisture resistant steel electrode for unalloyed construction steels.
  • Only low hydrogen alloy made in 1/16 (1.6mm) size.
  • Extremely smooth – spatter and turbulence free arc transfer.
  • Coating is totally non-conductive.
  • Unusually good AC welding characteristics.
  • Easy re-strike.
