DRAG CUP ASSEMBLY (S24114)

The drag cup protects the torch by preventing the torch from touching the workpiece.

SHIELD CUP ASSEMBLY (S24162)

This shields the torch tip and provides more visibil- ity to the workpiece than the drag cup. Note the shield cup does not prevent the torch tip from touching the workpiece.
