Summary/Abstract: Inverter welding sources are replacing conventional sources due to their convincing advantages - small size and weight, easy ignition and high quality of the arc, high energy and economic performance, operation in all conditions. The rapid development and implementation of transistor welding inverters became possible after the development of suitable power transistors (JGBT). Multi-station welding sources have more power than conventional welding sources. This places higher demands on their energy performance, which requires very precise design and selection of the element base. The purpose of this article is to study the energy performance of a multi-station inverter- welding source associated with switching losses at different welding currents.
