Izici zezimo ezijwayelekile zesithando somlilo zimi kanje:
1. I-electrode ifakwe ngokujulile futhi iqinile ekushajeni. Ngalesi sikhathi, i-crucible inkulu, indawo ebonakalayo inokungena komoya okuhle, ungqimba lwezinto ezibonakalayo luthambile, igesi yesithando somlilo ithunyelwa ngokulinganayo iphuma emlonyeni wesithando somlilo, ilangabi liwuwolintshi, indawo ebonakalayo ayinazo izindawo ezimnyama nezibilisiwe, futhi akukho ukuthungela okukhulu noma ukuwa kwezinto ezibonakalayo. Indawo ebonakalayo iphansi futhi imnene, futhi umzimba wekhoni ubanzi. Ishaja yesithando somlilo yehla ngokushesha, futhi indawo engaphakathi yesithando somlilo esinomthamo omkhulu kagesi yacwila kancane.
2. I-current ilinganisela futhi izinzile, futhi inganikeza umthwalo owanele.
3. Umsebenzi wokuthepha uhambe kahle uma kuqhathaniswa. I-taphole ivuleka kalula, iso lomgwaqo licacile, izinga lokugeleza kwensimbi encibilikisiwe liyashesha, lamanje lehla kakhulu ngemva kokuvula i-taphole, izinga lokushisa lensimbi encibilikisiwe liphezulu, kanye nezimo zokukhishwa kwe-slag kokubili zinhle. Esigabeni sakamuva sokuthepha, ingcindezi yegesi yesithando somlilo ekhishwe embobeni kampompi ayinkulu, futhi igesi yesithando somlilo iyachichima ngokwemvelo. Ukukhishwa kwensimbi kujwayelekile futhi ukwakheka kuzinzile.
