Popanga zitsulo, padzakhala kumwa kwa ma electrode a graphite, omwe amatha kugawidwa m'magulu abwino komanso ogwiritsidwa ntchito kwambiri. Pakudya kwanthawi zonse, pali mitundu itatu yakugwiritsa ntchito ma arc, kugwiritsa ntchito mankhwala komanso kugwiritsa ntchito oxidation. Ngakhale amayambitsa kumwa ma electrode a graphite, pali kusiyana kwa njira.
1, kumwa kwambiri ndi mlingo wovala makina mukamagwiritsa ntchito fracture.
2, kugwiritsa ntchito mankhwala kumatanthawuza momwe zonyansa zina zachitsulo, kashiamu ndi okusayidi wowopsa wa elekitirodi ndi chitsulo kapena momwe chitsulo chimayendera muzitsulo zosungunula, zomwe zimagwirizana mwachindunji ndi chitsulo ndi kukula kwa graphite electrode.
3, makutidwe ndi okosijeni kumwa amatanthauza kumwa mpweya anachita mu ndondomeko kupanga zitsulo, ndi mlengalenga mu ng'anjo, mpweya kutentha, mpweya otaya mlingo, opezeka mowa wabwinobwino wa 50% -60%, ndi mowa waukulu.
4, kugwiritsidwa ntchito kwa kuwala kwa arc kumatchedwanso evaporation mowa, chifukwa kutentha kwakukulu pakati pa elekitirodi ndi chiwongoladzanja chidzakhala chokwera mpaka 3000 ℃, padzakhala kupitiriza kumwa ma elekitirodi a graphite, omwe amawerengera pafupifupi 40% ya mowa wabwinobwino.
