摘要： A lighter (3) for mechanical machining operations, in particular for welding or thermal cutting of metals, comprising a base (4) and a support element (5) rotatably connected to the base (4) The support element comprises an insulating body (14) of ceramic material a first electrode (17) fully enclosed within the overall dimensions of the insulating body (14), and a converging surface (9) adapted to receive an inflammable gas flow from the nozzle (2) and to convey the gas flow towards the first electrode (17) The converging surface (9) defines said receiving portion (8) and is made of an electrically conductive material in order to define a second electrode (18) cooperating with the first electrode (17) for generating an electric arc capable of lighting the inflammable mixture. The electrodes (17,18) receive an electric potential difference from a piezoelectric element (29) activated by rotation of the support element (5) relative to the base (4) , following the thrust exerted by the nozzle (2) on the converging surface (9).
