CLASSIFICATION: E70T-2C per AWS A5.20, ASME SFA 5.20

Select Super 72 is designed to provide clean, porosity-free welds on heavily oxidized steels and steels with certain glass coatings. This carbon steel, flux cored electrode is intended for single pass welding in the flat and horizontal positions. 100% CO2 shielding gas is recommended.

APPLICATIONS: Select Super 72 is a superb selection for high speed welds on thin gauge carbon steels, particularly lap and butt welds. Typical applications include wheel and hub assemblies and hot water heater weldments, particularly the flue and bottom weldments.

DIAMETERS: .045", .052", 1/16", 5/64", 3/32", 7/64", 1/8"

SHIELDING GAS: 100% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Fast travel speeds and good weld bead profiles.
  • Complete coverage with very low slag volume.
  • Smooth spray-like arc transfer with low splatter.
