Kasancewa da tsayi ba kawai cikin sauƙi yana haifar da zubar da manyan ɗigo ba, amma kuma yana haifar da rashin kariya.
8. Al'amarin lokacin waldi irin ƙarfin lantarki da walda halin yanzu sun dace: baka yana ƙonewa a hankali, yana yin sauti mai kyau, gunkin walda yana girgiza dan kadan, taurin shine matsakaici, juzu'in voltmeter ba ya wuce 5V, lilon ammeter baya wuce 30A, kuma kada a sami girgiza a hannun hannu; Idan kan bindigar waldi ya ji laushi sosai kuma kusan babu girgiza, za a iya motsa bindigar walda ta kyauta. Ta hanyar lura da abin rufe fuska, wayar walda tana yawo a sama da narkakkar tafki, ta samar da wani babban narkakkar ball a karshen, wani lokacin kuma manyan digo-digo suna fantsama, wanda ke nuni da cewa karfin wutar lantarki ya yi yawa; Idan kan bindigar waldi ya ji da ƙarfi kuma yana girgiza sosai, za a iya jin sautin ƙararrawa, kuma akwai juriya yayin motsi da bindigar walda. Ta hanyar lura da abin rufe fuska, idan an saka wayar walda a cikin ruwan narkakkar kuma ta watsar da yawa, yana nuna cewa ƙarfin lantarki ya yi ƙasa; Yana da fa'ida a sami ɗan ƙaramin ƙarfin lantarki don hana haɗuwa da bai cika ba.
9. Gas kariya waldi tare da narkewar lantarki, daidaita walda halin yanzu shi ne don daidaita saurin ciyar da waya na walda waya, da kuma daidaita walda wutar lantarki ne daidaita da narkewa gudun na walda waya. Lokacin da saurin ciyarwar waya da saurin narkewa suka yi daidai, baka yana ƙonewa sosai.
