DETAILS

UltraCore® HD-C is a high deposition, all position E71T1 gas-shielded flux-cored electrode. Designed with a fast-freezing slag to make it easy for the operator to weld at high deposition rates, even when welding out-of-position. Intended for use with 100% CO2 shielding gas. This product is manufactured with steel made and melted in the U.S.A. It complies to Buy America (BA), Buy American (BAA), Build America, Buy America (BABA), and American Iron & Steel (AIS) standards.

Features

  • This product is manufactured with steel made and melted in the U.S.A. It complies to Buy America (BA), Buy American (BAA), Build America, Buy America (BABA), and American Iron & Steel (AIS) standards.
  • High Deposition Rates – increase weld deposition up to 10 lbs/hr out-of-position
  • Flat Bead Appearance – fast freezing slag for a flat bead shape and increased productivity in all positions, including vertical up
  • 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
