The advantages of thyristor control of welding transformers are considered. It is demonstrated that pulse stabilization of arcing in a thyristor-controlled transformer greatly expands its welding-technological capabilities and applications. A transformer of this type developed in PWI provides a smooth adjustment of the operational mode, "hot" and "cold" start, welding current modulation with an adjustable frequency. It can be used in AC and DC electrode welding
Keywords: arc welding, welding transformer, welding generator, thyristor regulation, welding current modulation, arcing stabilization device, technological properties of welding power sources, metal spatter
