UltraCore® HD-12M from Lincoln Electric is a mild steel, gas-shielded flux-cored wire designed to provide the high deposition rates and low temperature impact toughness equired in many heavy fabrication applications.
AWS / Classification: E71T-12M-JH8, E71T-1M-JH8, E71T-9M-JH8, E71T1-M21A4-CS2-H8
Overview

Lincoln UltraCore HD-12M is a mild steel, gas-shielded flux-cored wire designed to provide the high deposition rates and low temperature impact toughness required in many heavy fabrication applications.

Features
  • High Deposition Rates – increase weld deposition up to 14 lbs/hr out-of-position
  • Flat Bead Appearance – fast freezing slag for a flat bead shape and increased productivity in all positions
  • Wide Operating Range – operators can set the machine on a single setting and weld in all positions
  • Little or No Pre-Weld Clean up Required – weld over light rust, mill scale and primer
  • Low Temperature Impact Toughness – capable of exceeding 27 J (20 ft·lbf) at -40°C (-40°F)

Typical Applications

  • Heavy fabrication
  • Mining
  • General fabrication

Welding Positions

  • All

Shielding Gas
