Abstract

Flushing gas lines of a laser processing machine, by supplying a flushing gas to the system in a series of pressure impulses greater than a residual processing gas pressure after completion of a processing sequence, and allowing the supplied flushing gas to expand and mix with any residual gas between successive pressure impulses, to substantially clear the processing gas from the system.
