Kugirango wirinde kuberako ifeza yatwitswe, itumanaho rihagaze muburyo bugoramye, guhuza intera hagati igice.Arc rero ntabwo izaba iri hejuru yubusabane bwo gutwikwa.Nubwoko bwiza bwo guhuza, kandi kubishyira mubikorwa biragutse.Igikorwa cyakazi cyo guhuza amakuru gishyirwa imbere ibisabwa byinshi kubikoresho.Kuberako umuringa ufite amashanyarazi meza hamwe nubushyuhe bwumuriro.Gukomera birahagije.Ingingo yo hejuru yo gushonga, gutunganya byoroshye.Irakoreshwa cyane nkigice cyo guhuza igice cya voltage yamashanyarazi.Ariko ukoresheje ukuboko kwumuringa guhinduka okiside byoroshye, okiside yo kurwanya guhura.Mubice bimwe byumuzunguruko, umuringa utwikiriye ifeza igaragara hanze nyamukuru.

Ifeza ifite imiyoboro myiza, firime ya oxyde irayobora, irashobora kunoza imikorere yimikorere ya feza isize umuringa.Hamwe nogukoresha inshuro nyinshi kumashanyarazi, feza ihuza arc ingaruka zumuriro zariyongereye cyane, ubuso bwitumanaho burashobora kuba igihombo gikomeye, kubwibyo rero ifeza ihuza ubushyuhe, kurwanya arc, kurwanya abrasion kandi igashyira imbere ibisabwa byinshi.Powder metallurgie uburyo bwafunguye inzira nshya yo guteza imbere ibikoresho byitumanaho.

Ifu ya metallurgie aho gukoresha uburyo busanzwe bwa metallurgjiya, ariko ubwoko bubiri bwifu yicyuma ivanze hamwe muburyo bwo gukanda.Muri gaze ikingira (hydrogen) murwego rwo gucumura.Ubu bwoko bwa zahabu mubyukuri ni uruvange rwa taiwan.Kuberako inzira isa nibicuruzwa byubutaka, byitwa kandi ibumba.Umuvuduko mwinshi wumuzunguruko ukoreshwa cyane hamwe na tungsten y'umuringa, nikel ya feza, ifeza, grafite nkumwanya wo guhuza arc cyangwa impeta arc irwanya.Ikoreshwa muri relay, abahuza, guhinduranya ikirere, imipaka ntarengwa, kurinda moteri, moteri iciriritse, ibikoresho, ibikoresho byo murugo, amashanyarazi yimodoka (urumuri rworoshye no gutangiza moteri yimodoka), icyuma kirinda kumeneka.Ugereranije na okiside ya cadmium ya silver, okiside ya silver tin ntabwo irimo cadmium yubumara yuburozi, aho okiside yicyuma ifite ubushyuhe bwinshi bwumuriro, hamwe nubushyuhe bwiza bwamashanyarazi nubushuhe, muburyo bwo kuzimya bifite ubushyuhe bwinshi, kurwanya isuri kandi anti welding, kugirango tumenye neza imikorere yibikoresho byamashanyarazi, byongera ubuzima bwa serivisi.Kandi iterambere ryihuse rya silver tin oxyde, ndetse no muri bimwe mumashanyarazi adahinduye impinduka nini birashobora gukoreshwa muburyo butaziguye silver tin oxyde kugirango isimbure AgCdO.Imikoreshereze iri hagati ya 10A - 100A, mubikorwa byinshi hafi ndetse nziza kuruta ifeza ya kadmium oxyde.

Harimo ingano ya feza kugirango wirinde guhuza umuriro, guhuza itumanaho muburyo bugoramye, guhuza imbaraga mubice byo hagati.Arc rero ntabwo izaba iri hejuru yubusabane bwo gutwikwa.Nubwoko bwiza bwo guhuza, kandi kubishyira mubikorwa biragutse.Igikorwa cyakazi cyo guhuza amakuru gishyirwa imbere ibisabwa byinshi kubikoresho.Kuberako umuringa ufite amashanyarazi meza hamwe nubushyuhe bwumuriro.Gukomera birahagije.Ingingo yo hejuru yo gushonga, gutunganya byoroshye.Irakoreshwa cyane nkigice cyo guhuza igice cyumubyigano mwinshi.Ariko ukoresheje ukuboko kwumuringa guhinduka okiside byoroshye, okiside yo kurwanya guhura.Mubice bimwe byumuzunguruko, umuringa utwikiriye feza hanze yingenzi.

Ifeza ifite imiyoboro myiza, firime ya oxyde irayobora, irashobora kunoza imikorere yimikorere ya feza isize umuringa.Hamwe nogukoresha inshuro nyinshi kumashanyarazi, guhuza arc ingaruka zumuriro ziyongera cyane, ubuso bwitumanaho bushobora kuba igihombo gikomeye, bityo feza ihuza ubushyuhe, kurwanya arc, kurwanya abrasion hanyuma ugashyira imbere ibisabwa hejuru.Powder metallurgie uburyo bwafunguye inzira nshya yo guteza imbere ibikoresho byitumanaho.
