CLASSIFICATIONS: E70T-5C-H4, E70T-5M-H4 per ANSI/AWS A5.20, ASME SFA 5.20

Select 75 is a flux cored electrode designed with a basic slag system which provides better mechanical properties and diffusible hydrogen levels in the weld deposit than E70T-1 electrodes. Select 75 is intended for single and multiple pass welding of carbon and certain low alloy steels where a minimum tensile strength of 70,000 psi and good low temperature notch toughness are required.

APPLICATIONS: Select 75 is an ideal choice for weldments involving difficult steels, such as high carbon and free-machining types. It is well suited for heavy section fabrications such as crane sections, heavy machine bases, boom assemblies and construction equipment. Typical steels welded with this electrode are ASTM A36, A285, A515 Gr. 70 and A516 Gr. 70.

DIAMETERS:
.045", 1/16", 5/64", 3/32", 1/8"

SHIELDING GAS: 100% CO2, 75% Ar/25% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Excellent weld metal properties.
  • Slag removal and bead geometry similar to E7018 electrodes.
