constant-current power source, constant current power source, constant current characteristic power supply
järsult langeva tunnusjoonega vooluallikas, mille puhul keevitusvoolu kasvades langeb kaarepinge tunduvalt ja keevituskaare pikkuse muutudes keevitusvool muutub vähe (vrd püsivpingega vooluallikas), an arc welding power source that maintains current at a relatively constant level, regardless of fairly large changes in voltage caused by changes in arc length (compare: constant-voltage powder source)
