Kufotokozera: J707Ni ndi electrode yachitsulo yotsika kwambiri yokhala ndi chitsulo chochepa cha hydrogen sodium.Gwiritsani ntchito DCEP (mwachindunji ma elekitirodi abwino) ndipo mutha kuwotcherera m'malo onse.Chitsulo choyikidwa chimakhala ndi makina abwino.Poyerekeza ndi ma elekitirodi a J707, chinthu chachikulu cha J707Ni ndikuti kulimba kwa kutentha kochepa komanso kukana kwa ming'alu kwasinthidwa kwambiri.
Ntchito: Amagwiritsidwa ntchito powotcherera zitsulo zotsika kwambiri zamphamvu zofananira, monga 14MnMoVB, WEL-TEN70 ndi Japan HW56 ndi zida zina zachitsulo zotsika kwambiri.

Zindikirani:
1. Elekitirodi ayenera kuphika kwa ola 1 pa 350 ~ 380 ℃ pamaso kuwotcherera ntchito;
2. Ndikofunikira kuyeretsa dzimbiri, sikelo yamafuta, madzi, ndi zonyansa pazigawo zowotcherera musanawotchere;
3. Gwiritsani ntchito kachipangizo kakang'ono powotcherera.Njira yopapatiza yowotcherera ndiyoyenera.
