Item Details

  • 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.


  • 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 contaminants are present.


  • 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.


  • Protect yourself and others read the safety data sheet prior to using this product.
