Abstract. Stable and sustainable predicted development of industrial enterprises within global competition is ensured by regular improvement of technologies and introduction of innovative technological equipment. In terms of comparative analysis of the various power supplies application in the welding production, the equality of relative resource efficiency of various equipment and specific economic effect has been calculated. The research showed that the costs per 1 meter are the smallest for semiautomatic welding in a protective gas environment using inverter power supplies, contributing to the economic benefit during its application.
