FEATURES & APPLICATIONS

For moderate abrasion resistance combined with resistance to corrosion, erosion and thermal shock.

  • Extremely smooth running Alloy 6 Cobalt electrode.
  • Controlled weld bead allows for easy edge buildups.
  • Slag is self releasing.
  • Weld deposits are unusually fine rippled and uniform.
  • Available bare as product code 1296.
  • Special technology also performs on AC current.
