CLASSIFICATIONS: E71T-1C/E71T-1M, E71T-9C/E71T-9M per AWS A5.20,
ASME SFA 5.20
Select 714 is designed for applications where all position capability
is required but horizontal fillet and flat position welding is dominant.
Select 714 performs optimally with 100 percent carbon dioxide shielding,
but can be used with 75-80 percent argon/balance carbon dioxide,
with no deterioration in welding performance.
APPLICATIONS: The good toughness properties of Select 714
make it an especially smart choice for the welding of fine grained
steels, such as ASTM A515 and 516. Typical applications are structural
welds, general steel fabrication, construction equipment and general
railcar welding.
DIAMETERS: .035", .045", .052", 1/16"
SHIELDING GAS: 100% CO2, 75-80% Ar/balance CO2, 35-50 cfh
WELDING POSITIONS: All positions
CHARACTERISTICS:
Much lower fume emissions than conventional rutile-based electrodes.
Specially formulated to produce low spatter horizontal fillets.
Smooth weld bead profile and excellent tie-in.
Very good CVN toughness values at subzero temperatures.
