A plier (35, 36) of which the jaws are provided with claws (38, 39) of electrically good conductor metal, threaded in a complementary way to that of the threaded portion (10) of the cap (4) of the device (1), grips the device (1) by that threaded portion (10) of the cap (4) while strongly pressing the capsule (17) on the threaded end (10) of the cap (4) and heating those parts by Joule effect. The plier rests on a portion (26) which rests itself on the frame (25) of the machine. Hence, the insulating portion of ceramic material (2) of the device is not subjected to any stress due to the pressure exerted during such welding operation. |
