Abstract

An engine driven welding machine in which a welding generator is driven by an engine, and the engine performs an idle operation when a welding operation is stopped by including an engine stop signal forming circuit which forms a stop signal for stopping an operation of the engine when time of the idle operation exceeds a predetermined time, a direct-current power supply connected to an output terminal of the welding machine, voltage detecting means which detects a voltage change of the output terminal, a restart detecting circuit which forms a restart signal for restarting the engine when the detected voltage by the voltage detecting means shows a predetermined change mode for starting the welding operation, and an engine control circuit which stops the engine in response to the stop signal, and restarts the engine in response to the restart signal.

Abstract

A coupling plate for an engine-driven generator on which a balance weight can be mounted and which is simple in structure and is constituted by a same hole making pattern. In a coupling plate for an engine-driven generator driving a generator by an engine, a plurality of elastic disks overlapped integrally are provided, and the elastic disks have one of the inner circumference side and the outer circumference side in the radial direction connected to the engine and the generator as the input side and the other as the output side, and in each of the elastic disks, a plurality of holes including small-diameter weight mounting holes and large-diameter weight escape holes distributed/arranged with a predetermined interval in the circumferential direction are drilled so that the holes of the respective disks are positionally overlapped with each other.

Abstract

To provide a protective cover capable of enhancing convenience in connecting and disconnecting an external output line and the like without impairing safety. In a protective cover placed on a side wall of a casing and covering a hollow part in which an output part of an apparatus housed in the casing is provided, the cover is characterized by including an outer lid which is supported by a hinge provided at an upper end to be openable and closable, and is provided, at a part close to a lower end, with a first locking member engaging with a catching member that is provided at a lower part of the hollow part, and an internal lid which is rotatably mounted to a position corresponding to the output part in an inner surface of the aforesaid outer lid to cover the output part. The internal lid is supported by a hinge.
