Ibisobanuro: J707Ni ni electrode nkeya-ikomeye cyane ya electrode hamwe na sodium ya hydrogène nkeya.Koresha DCEP (itaziguye ya electrode nziza) kandi irashobora gusudira mumyanya yose.Icyuma cyabitswe gifite imiterere yubukanishi.Ugereranije na electrode ya J707, ikintu nyamukuru kiranga J707Ni nuko ubukonje buke hamwe no kurwanya ubukana byateye imbere cyane.
Gushyira mu bikorwa: Byakoreshejwe mu gusudira ibyuma-bito bito-bikomeye-ibyuma byubaka byingero zingana, nka 14MnMoVB, WEL-TEN70 hamwe nu Buyapani HW56 hamwe nandi mavuta aciriritse-yimbaraga zikomeye.

Icyitonderwa:
1. Electrode igomba gutekwa kumasaha 1 kuri 350 ~ 380 ℃ mbere yo gusudira;
2. Ni ngombwa guhanagura ingese, igipimo cyamavuta, amazi, n’umwanda ku bice byo gusudira mbere yo gusudira;
3. Koresha ibikorwa bigufi arc mugihe cyo gusudira.Inzira ifunganye yo gusudira irakwiriye.
