Since it is passed through the nozzle, handling is difficult when working. Further, when the piston is reciprocated by compressed air, if it is continuously used in winter, the exhaust port of the cylinder, which is the swinging means, may condense and freeze up, leading to malfunction. If the cylinder freezes, it will not be possible to supply the thread evenly to the construction area. Once frozen, work will be interrupted until it is thawed and restarted.
