UltraCore® HD-12C 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-12C-JH8, E71T1-C1A4-CS2-H8
Overview

Lincoln UltraCore HD-12C 0.0045 welding wire 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)
  • Select packaging and diameter are available meeting Buy America & American Iron & Steel (AIS) standards.

Typical Applications
