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
