FEATURES & APPLICATIONS

DESCRIPTION: 1180 is an outstanding welding electrode for welding higher strength piping, castings and forgings. The coating is specially formulated to resist moisture pick-up under conditions of high heat and humidity. The electrode offers resistance to moisture reabsorption which helps prevent hydrogen cracking and aids in elimination of starting porosity. Definitely a preferred electrode with high operator appeal.

APPLICATIONS:

1180 is used in welding chrome-moly pipes and boiler work.

FEATURES:

  • Excellent arc characteristics
  • Low spatter level
  • Quick and easy slag removal
  • Low moisture reabsorption
  • Low smoke level
  • Low hydrogen, less than 4 ml/100g

BENEFITS:

  • Stable, easy to control arc
  • Improves weld bead appearance, higher deposition
  • Reduce clean-up time
  • Prevents starting porosity
  • Welder safety and comfort
  • Resistant to hydrogen-induced cracking
