FEATURES & APPLICATIONS

Hardest cobalt based electrode with very low coefficient of friction.

  • Extremely smooth running Alloy 1 Cobalt electrode.
  • Extra hardness for maximum edge retention.
  • Slag is self releasing.
  • Weld deposits are unusually fine rippled and uniform.
  • Available bare as product code 1291.
  • Special technology also performs on AC current.
