Isifudumezi sombhobho wokuqhuma luhlobo lwezixhobo zokugcina amandla ezifudumeza kuqala izinto, ezifakwe phambi kokuba izixhobo eziphathekayo ziqonde ukufudumeza ngokuthe ngqo kwezinto, ukuze zifudunyezwe kumjikelo wobushushu obuphezulu, kwaye ekugqibeleni. ukufezekisa injongo yokonga amandla. Isetyenziswa ngokubanzi kwi-preheating ye-oyile enzima, i-asphalt, ioli ecocekileyo kunye nezinye ioli yeoli. I-heater yombhobho yenziwe ngamacandelo amabini: umzimba kunye nenkqubo yokulawula. Isixhobo sokufudumeza senziwe ngombhobho wensimbi engenasici njengomkhono wokukhusela, ubushushu obuphezulu be-alloy wire, i-crystalline magnesium oxide powder, eyenziwa yinkqubo yoxinzelelo. Icandelo lolawulo liqulunqwe yisekethe yedijithali ephuculweyo, i-trigger yesekethe edibeneyo, i-high reverse voltage thyristor kunye nolunye umlinganiselo wokushisa ohlengahlengiswayo kunye nenkqubo yokushisa rhoqo ukuqinisekisa ukusebenza okuqhelekileyo kwesifudumezi sombane.
