Abstract
Molten metal created during cutting of a workpiece by a plasma-arc torch is discharged downwardly into a tubular collector duct. A power-rotated cutter is located adjacent the upper end of the duct and shaves dross from the underside of the workpiece as the latter is moved beneath the torch, the dross also being discharged downwardly into the duct. Water is sprayed into the duct to cool the duct and is also sprayed against the rotary cutter to cool the cutter as the dross is shaved from the workpiece.
