The chitsulo chosungunuka ikhoza kuyambika, ndipo pali overcurrent pamene mphamvu ikuwonjezeka. Zomwe zimayambitsa:

① Transformer yapakati pafupipafupi ndiyowonongeka kapena yolakwika,

②The inverter pulse transformer ndiyowonongeka kapena yolakwika,

③Inverter SCR kusweka kofewa kapena kwapakatikati,

④Kutayikira kwa ma capacitor oyambira amtundu wapakati pafupipafupi,

⑤The capacitor yamagetsi yamagetsi imakhala ndi kuwonongeka kofewa, ndipo kutsekemera kwa mphete ya ng’anjo kapena chitsulo chamkuwa sikukhazikika bwino kapena kufupikitsidwa pang’ono.
