CLASSIFICATION: EC409Nb per AWS A5.22, ASME SFA 5.22

Select 409Cb is a composite metal cored, stainless steel electrode for gas-shielded arc welding. This product is intended for welding ferritic stainless steel sheet and thin gauge material where niobium (columbium) stabilization is preferred over titanium. Arc transfer is a smooth spray with minimal spatter; bead appearance is smooth and clean.

APPLICATIONS: Select 409Cb produces a ferritic stainless steel deposit which is ideal for welding thin gauge ferritic stainless in the fabrication of automotive exhaust systems. Typically, these components are manifolds, mufflers, catalytic converters and tubing. The tubular wire characteristics provide better performance on gaps and poor fit up than solid wires.

DIAMETERS: .045", .052", 1/16"

SHIELDING GAS: 98% Ar/2% O2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Bridges gaps and handles poor fit up better than solid wire.
  • Faster travel speeds than solid wire.
  • Smooth spray transfer with minimal spatter.
  • Performs well when oil or other contaminents are present.
