Abstract
A process and apparatus for protecting a confinement chute from slag build-up caused by accumulation of spatter particles generated by cutting a workpiece by a hot discharge such as a plasma arc or laser, including a high velocity flow of gas such as air directed over the chute internal surface to deflect and cool the spatter particles. The surface is chrome plated to reduce the tendency for adhesion of the particles to the surface.
