<P>PROBLEM TO BE SOLVED: To provide a method for starting an arc thermal spraying by which the operation for starting or finishing the thermal spraying can be performed by a single hand, a uniform film is deposited on a work by correctly operating a thermal spraying gun while reducing physical fatigue of hands during a thermal spraying work, and it is unnecessary to perform a repair work due to that the thermal spraying is started when a worker depresses a start switch erroneously. <P>SOLUTION: In this method, if the period of time that the worker depresses the start switch to maintain an ON-state is within a predetermined value, the feeds of wire and thermal spraying current are not started, and the ejection of compressed gas is stopped. On the other hand, if the period of time to maintain the ON-state of the start switch is the predetermined value or above, the feeds of the wire and energization of the thermal spraying current are started to start the thermal spraying. <P>COPYRIGHT: (C)2004,JPO |
