CLASSIFICATIONS: E70T-1C, E70T-9C per AWS A5.20, ASME SFA 5.20

Select 71A is a carbon steel, flux cored electrode designed for the single and multiple pass welding of carbon and certain low alloy steels in the flat and horizontal positions. It provides smooth performance with superior bead shape and slag peeling.

APPLICATIONS: Select 71A is a general purpose electrode with extremely high welder appeal. It has a stable arc, with low spatter, over a broad current range. This new wire has excellent wetting characteristics, resulting in superior bead shape and the slag is typically self peeling. Select 71A is an ideal choice for welding plates such as ASTM A36, A285, A515 and A516, commonly found in earthmoving equipment, mining machinery, structural steel and railcar fabrication.

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

SHIELDING GAS: 100% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • High level of oxidation facilitates welding over mill scale, rust and other contaminants.
  • Extremely smooth welding arc over a broad range of amperage and voltage.
  • Quite low spatter.
  • Slag removes very easily.
