Abstract

The laser machining head has a nozzle electrode (15) screwed coupled coaxially to an annular isolation element (1) mounted on the head. A common helical spring (24) sits on the outer surfaces of the isolation element and nozzle electrode and is wound so that its helix diameter reduces when the nozzle electrode is unscrewed.
