Select 722 is a flux cored electrode formulated to enhance all position
welding performance, particularly in the overhead position. The
preferred shielding gas is 100 percent carbon dioxide but Select
722 is also designed to weld on blends of 75-80 percent argon/balance
carbon dioxide.
APPLICATIONS: The combination of welding performance and
mechanical properties make Select 722 well suited to demanding applications
such as shipbuilding, railcar manufacture, structural welding and
general fabrication.
DIAMETERS: .045", .052", 1/16"
SHIELDING GAS: 100% CO2, 75-80%Ar/balance CO2, 35-50 cfh
WELDING POSITIONS: All positions
CHARACTERISTICS:
Smooth arc transfer with very little spatter emission.
Quick freezing slag provides exceptional weldability.
Deposits weld bead without convexity.
