ABSTRACT:
The inventive system treating the surface of a material by utilizing high intensity ultraviolet light for glazing, cleaning and other such purposes. The system includes a high intensity ultraviolet light is generated by a liquid jet plasma pinch unit, and is repetitively pulsed to raise the surface temperature of the material rapidly to a predetermined high temperature. In one form of the invention, the system is mounted either on a vehicle, or on an overhead structure for facilitating the movement of the pinch unit to the surface to be treated. In another form of the invention, the pinch unit includes a light emitting assembly which can be lowered into an opening in a workpiece to be treated.
