CLASSIFICATION: E70T-4 per AWS A5.20, ASME SFA 5.20

Select 74 is a self-shielded, flux cored electrode designed for use in the multiple pass welding of carbon steels. This electrode is intended for flat position welding of grooves and fillets and horizontal fillet welding with extremely high deposition rates.

APPLICATIONS: Select 74 is ideally suited for welding applications where gas-shielded electrodes may have problems, such as outdoors or in windy conditions. These would typically be light gauge steel plate fabrication or general purpose fabrication of carbon steels. Select 74 is also a good choice in poor fit up situations or when extended stickouts must be used in hard-to reach areas.

DIAMETERS: .120", 1/16", 5/64", 3/32"

SHIELDING GAS: Self-shielded

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Extremely high deposition rates.
  • Minimizes hot cracking on steels high in sulfur.
  • Facilitates welding fillets with gaps or poor fit up better than E70T-1 electrodes.
  • Very good slag detachment.
