CLASSIFICATION: E110C-K4 per AWS A5.28, ASME SFA A5.28

APPROVALS: CWB E76C-K4-H4

Select 110C-K4 is a low alloy steel, composite metal cored electrode designed for single and multiple pass welding of certain carbon and low alloy steels where a minimum tensile strength of 110,000 psi is needed in the deposited weld metal.

APPLICATIONS: Select 110C-K4 is an excellent choice for joining low alloy, high strength steels such as HY-80 and A514. Earthmoving equipment, mining trucks and machinery and heavy equipment trailers are some areas where these steels may be utilized. This electrode may also be used for overlay or surfacing in certain applications.

DIAMETERS: .035", .045", .052", 1/16"

SHIELDING GAS: 75-95% Ar/balance CO2, 98% Ar/2% O2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Provides exceptional mechanical properties and outstanding welder appeal.
  • Arc transfer is pure spray with virtually no spatter emission.
  • Minimal subsurface porosity.
  • Faster travel speeds and greater productivity than solid wires.
  • Eliminates "cold-lap".
