CLASSIFICATIONS: E71T-1C, E71T-1M per AWS A5.20, ASME SFA
5.20
Select 710 is an all position, flux cored electrode which is intended
for the single and multiple pass welding of carbon and certain low
alloy steels where a minimum tensile strength of 70,000 psi is required.
Gas-shielding can be either 100% CO2 or 75% Ar/25% CO2.
APPLICATIONS: Select 710 is a superb choice for the general
purpose, flux cored welding of steels requiring a minimum of 70,000
psi tensile strength. Typical applications include structural steel,
farm machinery, construction equipment and general carbon steel
fabrication.
DIAMETERS: .035", .045", .052", 1/16"
SHIELDING GAS: 100% CO2, 75-80% Ar/balance CO2, 35-50 cfh
WELDING POSITIONS: All positions
CHARACTERISTICS:
Deep penetration eliminates lack of fusion problems.
Smooth and stable arc transfer with low spatter emission.
Fast freezing slag removes easily.
Outstanding welder appeal.
