The paper analyzes the feasibility and advisability of the use of the multiple automatic control systems with a feedback complex, intended to meet the challenges of the current and voltage stabilization of the welding process, and assess the impact of tools on the continuity and stability of the electrode metal transfer, as well as a possibility of the mass transfer control. The authors investigated the cruise control wire feed with a positive feedback voltage of the welding process and negative current feedback arc characteristics for different types of the welding power source. In order to evaluate the effectiveness of development of a system of external disturbances, experiments were conducted on the conventional surfacing rolls on 10HSND plate steel with grooves milled across. The authors used a welding current source inverter of a modern type. Analysis of the results was carried out on the basis of the statistical processing of the current and voltage waveforms of the arc in a number of experiments. It was shown that both the investigated and the automatic control systems ensure stability of the welding process and the required accuracy and speed of running of the external disturbances, leading to changes in the arc length. The dynamic characteristics of the welding power source inverter are sufficient to stabilize the current in the electrode metal transfer. The automatic control system with a negative feedback welding current does not have an impact on the welding process and the system of self-regulation of the arc, and therefore its use in some cases is inappropriate. Understanding, that stabilization is one of the possible boundary impacts, suggests a possibility of influencing the process of the electrode metal transfer not only by imposition of the current pulses, but also by its more complex modulation.
