 Print Sheet


CLASSIFICATION: E100T1-K3C per AWS A5.29, ASME SFA 5.29

Select 100-K3, with a minimum tensile strength of 100 Ksi and good CVN toughness levels, is a gas-shielded electrode for flux cored arc welding of certain high strength, low alloy steels. This electrode is intended for single and multiple pass welding in horizontal fillets and the flat position.

APPLICATIONS: Select 100-K3 is an excellent selection for welding steels such as A514 and HY-80. These steels are typically used in fabrications such as heavy crane assemblies, mining machinery and large earthmoving equipment.

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

SHIELDING GAS: 100% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Good CVN toughness at lower temperatures.
  • Exhibits good bead profiles with excellent slag detachment.
  • Relatively low spatter levels.
