Tru-Core® MC 80C-Ni1 is a low alloy steel, composite metal cored electrode for gas shielded arc welding low alloy, and certain carbon, steels requiring tensile strengths in excess of 80 ksi and good CVN values at temperatures as low as -50°F. This electrode is intended to be used with a shielding gas blend of 95-99% Argon/Balance Oxygen, but performs well with 75- 95% Argon/Balance Carbon Dioxide as well. The MC 80C-Ni1 can be used in single and multiple pass applications, both in fillets and groove welds.

CHARACTERISTICS

Excellent mechanical properties

Nearly slag free welds

Flat bead geometry

Smooth arc transfer

Easy clean-up

Excellent feedability

Good low-temperature CVN properties

Better sidewall fusion than solid electrodes

APPLICATIONS

Tru-Core® MC 80C-Ni1 is a good choice to weld steels from ¼” thickness up to heavy plates sections. Typical grades: ASTM A203 Grade A, ASTM A352 Grades LC1 and LC2, and Weathering steel such as ASTM A588. Some examples are:

  • Power transmission poles
  • Mining machinery
  • Construction equipment
  • Shipbuilding

TYPICAL APPLICATION SHIELDING GAS BLENDS

95-99% Argon/Balance O2

75-95% Argon/Balance CO2

Flow Rate: 35-45CFH

WELDING POSITIONS

All position welding is possible when using the correct shielding gas blends, welding process and welding parameters.

STORAGE

Welding wire should be stored in a dry, enclosed environment and in its originally-sealed package.
