Abstract

PURPOSE:To maintain the safety by closing a safety switch at the time of finishing the stage to mount an insulating cap on a nozzle and actuating the safety switch even if it is forgotten to screw the nozzle on a body. CONSTITUTION:When an electrode 3, the nozzle 31 and the insulating cap 34 are mounted on the body 30, the electrode 3 is screwed on the body 30 and then, the nozzle 31 is screwed on the body 30. Next, the insulating cap 34 is held by the nozzle 31. When the holding of the insulating cap 34 by the nozzle 31 is completed, the safety switch 39 is closed. By this method, unless the nozzle 31 is screwed on the body 30, the insulating cap 34 cannot be mounted thereon and moreover, the safety switch 39 is also not closed. Accordingly, since it cannot be forgotten to screw the nozzle 31 on the body 30, the safety can be maintained.
