Abstract
Harmonic composition of three-phase electric mains at operation of welding power sources was studied. It is shown that welding sources generate higher current harmonics into the mains that impairs the quality of power. Application of higher harmonic filters is recommended to reduce the impact of welding power sources on the mains
 
 
Keywords: arc welding, power sources, three-phase mains, power quality, higher harmonics, filters
