Tru-Core® FC 71T is a flux cored, gas shielded, allposition electrode intended to weld carbon steel, as well as certain low alloy steels, where a minimum tensile strength of 70,000 psi is required. Tru-Core® FC 71T is intended for single and multiple pass welding using 100% CO2 or 75-80% Argon/balance CO2 mixtures, for welding in all positions. Major advantages of this electrode include deep penetration, smooth stable arc transfer, low spatter levels and a slag system specially formulated for a high melting point. This provides a very quick-freezing slag.

CHARACTERISTICS

PRODUCT FEATURES:

  • Flat bead geometry
  • Easy slag removal
  • Excellent feedability
  • Smooth arc transfer
  • Excellent mechanical properties

MANUFACTURING ADVANTAGES:

  • Patented forming, feeding and drawing equipment
  • Consistent strip-to-core ratio
  • Precise thermal treatment that controls the type, amount and uniformity of surface oxides on the wire
  • Consistent diffusible hydrogen levels

APPLICATIONS

Tru-Core® FC 71T can be used for welding most carbon steels and certain low alloy steels. It is ideal for welding gauges varying from 10-gauge sheet metal to heavy plate sections.

Some examples are:

  • Structural Steel
  • Heavy Equipment
  • Railcar Construction
  • Mining Machinery
  • General Fabrication

TYPICAL APPLICATION SHIELDING GAS BLENDS

75% Argon/25% CO2

100% CO2

Flow Rate: 35-45 CFH

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.
