DETAILS

UltraCore® HD-M is a mild steel, gas-shielded flux-cored wire designed to provide high deposition rates and flat bead appearance required in many out-of-position applications.

Features

  • Increase weld deposition to more than 10 lbs./hr. out-of-position
  • Fast freezing slag for a flat bead shape and increased productivity in all positions, including vertical up
  • Operators can set the machine on a single setting and weld in all positions

Typical Applications

  • Shipbuilding
  • General fabrication

Welding Positions

  • All

Shielding Gas

  • Mixed Shielding Gas
