CLASSIFICATIONS: E71T-1M, E71T-9M per AWS A5.20, ASME SFA 5.20

Select 717 is a flux cored electrode specially developed to weld with high argon gas mixtures. Intended for single and multiple pass welding of carbon steels in all positions. The recommended shielding gas is argon with 5-25% carbon dioxide.

APPLICATIONS: Select 717 is best suited for situations where lower fume levels are required or higher out of position productivity is desired. Select 717 may be used to join steels such as ASTM A36, A515 Gr 70, A516 Gr70 and other fine grained steels. Typical applications include railcars, heavy equipment, structural fabrication and general plate fabrication.

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

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

WELDING POSITIONS: All positions

CHARACTERISTICS:

  • Very smooth arc transfer with virtually no spatter.
  • Exceptionally low fume generation.
  • Maintains handling characteristics in higher argon mixtures.
  • Quick freezing slag allows for very high deposition rates.
