ELECTRIC WELDER

摘要

FIELD: mechanical engineering; welding equipment. SUBSTANCE: welding electrode is connected to supply source together with piezoelectric generator as arc starting device for three-phase or direct current systems or electrostatic machine for single-phase current systems provides stabilization of arc and high quality of welding owing to reliable ionization of electrode-workpiece gap at reduced values of voltage and power of supply source. EFFECT: improved quality of welding. 1 dwgm
