Select 737 is a carbon steel electrode for flux cored arc welding with
an external shielding gas. This electrode is 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. The recommended
shielding gas is 75 percent Argon/25 percent Carbon Dioxide, with a
flow rate of 40 cfh and a dew point of at least -40 degrees F.
APPLICATIONS: The combination of weldability and good mechanical
properties make Select 737 a superb choice for 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.
