A number of problems, related to synergetic control of the process of the arc mechanized and automatic welding with the regulated pulse feed of the electrode wire, are considered. It is noted, that the known systems with a synergetic control due to the impulse algorithms of operation of modern structures sources can be replaced by more simple and less power-intensive systems with the use of the controlled pulse feed of electrode wire. It is determined, that in the systems with the controlled pulse feed of electrode wire the various structures of feed-backs are used on the parameters of an arc process. It is shown, that the required component of feed-back structure in the considered process is a feed-back on the welding current.
