It is shown that the main drawback of multistation systems based on ballast rheostats, consisting in increased energy consumption, can be prevented in their replacement by electronic controllers of welding current made on power transistor switches of the third and fourth generations. These schemes are based on welding current coverters using pulse-width modulators with wide functional capabilities of welding-technological properties
