The invention discloses a rotating arc length change value detection method based on rotating arc sensing signal characteristics, which comprises a working principle of the rotating arc length change value detection method and a relation between a rotating arc length change coefficient and a welding current and a change amount thereof. And establishing a relation model of a rotating arc length change coefficient and a rotating arc sensing signal characteristic quantity, and detecting a rotating arc length change value. The rotating arc length change value can influence the stability of the rotating arc, if the arc length change value is larger, the arc stability is poorer, and if the arc length change value is smaller, the arc stability is better. By means of the method, the rotating arc length change value can be detected based on the characteristics of the rotating arc sensing signals, a foundation is laid for automatic control over the rotating arc length change value of a machine, intelligent control over
