Pakadali pano, njira zazikulu zochepetsera kugwiritsa ntchito ma electrode ndi izi:
Konzani bwino magawo a dongosolo la magetsi. Magawo a magetsi ndi zinthu zofunika kwambiri zomwe zimakhudza kugwiritsidwa ntchito kwa ma elekitirodi. Mwachitsanzo, pa ng'anjo ya 60t, pamene magetsi a mbali yachiwiri ndi 410V ndipo mphamvu yamagetsi ndi 23kA, kugwiritsa ntchito ma elekitirodi akutsogolo kungachepetsedwe.
Electrode yopangidwa ndi madzi yatengedwa. Electrode yopangidwa ndi madzi ndi mtundu watsopano wa electrode yomwe yapangidwa kunja kwa dziko m'zaka zaposachedwa. Electrode yopangidwa ndi madzi imapangidwa ndi gawo lapamwamba la chubu chachitsulo chozizira ndi madzi ndi gawo lotsika la graphite, ndipo gawo lopangidwa ndi madzi limawerengera pafupifupi 1/3 ya kutalika kwa electrode. Popeza palibe kutentha kwambiri (graphite oxidation) mu gawo la chubu chachitsulo chozizira ndi madzi, kusungunuka kwa electrode kumachepa, ndipo gawo la chubu chachitsulo chozizira ndi madzi limasunga kukhudzana bwino ndi chogwirira. Popeza ulusi wa gawo lozizira ndi madzi ndi gawo la graphite umagwiritsa ntchito mtundu wozizira ndi madzi, mawonekedwe ake ndi okhazikika, osawonongeka, ndipo amatha kupirira mphamvu yayikulu, zomwe zimapangitsa kuti mawonekedwe a electrode akhale olimba, motero amachepetsa kwambiri kugwiritsa ntchito electrode.
Njira yotsutsana ndi okosijeni ya electrode ya graphite yopopera madzi yagwiritsidwa ntchito. Poganizira momwe ma electrode amagwiritsidwira ntchito poyenga, njira zaukadaulo zopopera madzi ndi kupewa okosijeni zimagwiritsidwa ntchito, kutanthauza kuti, chipangizo chopopera madzi chozungulira chimagwiritsidwa ntchito pansi pa griper ya electrode kuti chipopere madzi pamwamba pa electrode, kuti madzi aziyenda pansi pa electrode, ndipo chitoliro chozungulira chimagwiritsidwa ntchito kupopera mpweya wopanikizika kupita pamwamba pa electrode pamwamba pa chivundikiro cha ng'anjo, kuti achepetse kuyenda kwa madzi. Pogwiritsa ntchito njira iyi, kugwiritsa ntchito electrode yachitsulo cha tani kunachepa moonekeratu. Ukadaulo watsopano umagwiritsidwa ntchito koyamba mu ng'anjo yamagetsi yamphamvu kwambiri. Njira yopopera madzi yozungulira ndi yosavuta, yosavuta kugwiritsa ntchito komanso yotetezeka.
Ukadaulo wopaka pamwamba pa ma electrode. Ukadaulo wopaka pamwamba pa ma electrode ndi njira yosavuta komanso yothandiza yochepetsera kugwiritsa ntchito ma electrode.
Zipangizo zophikira ma elekitirodi zomwe zimagwiritsidwa ntchito kwambiri ndi aluminiyamu ndi zinthu zosiyanasiyana zadothi, zomwe zimakhala ndi kukana kwamphamvu kwa okosijeni pa kutentha kwambiri ndipo zimatha kuchepetsa bwino kugwiritsa ntchito okosijeni pamwamba pa mbali ya elekitirodi.
Ma electrode oyezera amagwiritsidwa ntchito. Ma electrode oyezera amayezera kuviika ma electrode mu mankhwala opangira mankhwala ndikupangitsa kuti pamwamba pa ma electrode pagwirizane ndi mankhwalawo kuti awonjezere kukana kwa ma electrode ku kutentha kwambiri. Kugwiritsa ntchito ma electrode kumachepetsedwa ndi 10% ~ 15% poyerekeza ndi ma electrode wamba.
