Select 70C-3 Close Window
 Print Sheet


CLASSIFICATIONS: E70C-3M per AWS A5.18, ASME SFA 5.18

Select 70C-3 is a premium metal cored electrode intended for single and multiple pass welding of carbon and certain low alloy steels, where a minimum tensile strength of 70,000 psi is required in the deposited weld metal.

APPLICATIONS: The versatility of Select 70C-3 makes it an ideal choice for those applications where solid wire is inadequate or the slag from flux cored wire is unwanted. Typical areas of appeal are propane and air compressor tanks, farm machinery frames and assemblies, heavy gauge sheet metal and general steel fabrication. The absence of slag and spatter residue facilitates painting after the welding operation is completed.

DIAMETERS: .035", .045", .052", 1/16", 5/64", 3/32"

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

WELDING POSITIONS: All Positions - .035"-1/16"; Flat and Horizontal - 5/64"-3/32"

CHARACTERISTICS:

  • Increased productivity due to faster welding speeds.
  • Very smooth spray transfer with virtually no spatter emission.
  • Better fusion than solid wire.
  • Elimination of cold lap.
  • Slag-free welds enhance productivity.
