Metalshield® MC®-120 from Lincoln Electric is a low alloy metal cored wire with low spatter and excellent arc stability.

DETAILS

Metalshield® MC®-120 from Lincoln Electric is a low alloy metal cored wire with low spatter and excellent arc stability.

Features

  • H4 diffusible hydrogen levels
  • Low spatter and excellent arc stability
  • Deoxidizing agents minimize pre- and post-weld clean up
  • Enhanced silicon island management
  • Low temperature impact properties – Charpy V-Notch test results capable of exceeding 27 J (20 ft•lbf) @ -51°C (-60°F)
  • Excellent bead shape and profile

Typical Applications

  • Robotics/hard automation
  • HSLA and quenched and tempered steels (i.e., HY-100 and ASTM A514)
  • Crane fabrication
  • Heavy equipment
  • Pressure vessels

Welding Positions

  • All

Shielding Gas

  • 75-90% Argon / Balance CO2, Flow Rate: 40-60 CFH
