The paper analyses the features of design of pulsed wire feed mechanisms based on quasi-wave converters. It is shown that the maximal acceleration voltage achieved in the pulse can be essentially increased by cascade connection of several modulators or by changing the modulating pulse frequency. Conditions are determined under which the mechanism designs will be optimal in terms of both their manufacture and adjustment of the output parameters. The main principles of designing new types of pulsed feed mechanisms are defined that allow for the features of their mounting in the mechanised arc welding equipment.
