Intonga yokwelulela ye-Ni307-2 ikwabalasele ekunciphiseni ixesha lokungasebenzi. Ukwambathiswa kwe-hydrogen ephantsi kwee-electrodes ze-Ni307-2 akupheleli nje ekuphuculeni ukuthembeka kwe-weld, kodwa kukwayenza lula inkqubo yokwelulela ngokunciphisa imfuneko yonyango lwangaphambi nasemva kokuwelulela. Olu phawu lwee-electrodes ze-Ni307-2 luluncedo kakhulu kumsebenzi wokulungisa nokugcina intsimi, apho ukusebenza kakuhle nokuthembeka kubalulekile. Ii-electrodes ze-Ni307-2 zinceda ukonga ixesha kunye nezixhobo ngokunciphisa amathuba okuba neziphene kunye nokuphinda kusetyenziswe.
Nangona iingenelo zobugcisa zisizathu esikhulu sokukhetha intonga yokuwelda ye-Ni307-2, intonga yokuwelda ye-Ni307-2 nayo yenzelwe ukuba kube lula ukuyisebenzisa. Ezi electrode zivelisa ukuchitheka okuncinci kunye nomsi, zidala indawo yokusebenza ecocekileyo nekhuselekileyo kwaye zonga ixesha lokucoca indawo yokusebenza. Iimpawu ezithambileyo zentonga yokuwelda ye-Ni307-2 zivumela ulawulo oluchanekileyo, oluvumela abawelda ukuba bafumane iziphumo ezisemgangathweni ophezulu nokuba kwimisebenzi yokuwelda enzima okanye ebuthathaka. Ezi mpawu zenza intonga yokuwelda ye-Ni307-2 ibe lukhetho oluhle kakhulu kubawelda abanamava nabaqalayo ngokufanayo, ukuqinisekisa ukusebenza rhoqo kwabawelda bazo zonke izakhono.
Uzinzo lolunye uphawu oluphambili lwentonga yokuwelda ye-Ni307-2. Ngokubonelela ngee-welds ezihlala ixesha elide nezithembekileyo, intonga yokuwelda ye-Ni307-2 inciphisa isidingo sokulungiswa rhoqo kunye nokutshintshwa, inceda ekunciphiseni inkunkuma yezinto kunye nokusetyenziswa kwamandla. Ukuhambelana kwentonga yokuwelda ye-Ni307-2 kunye neendidi ezahlukeneyo zesinyithi kunye nee-alloys kukwaxhasa ukulungiswa kunye nokusetyenziswa kwakhona kweendawo ezikhoyo, okuhambelana neendlela ezinobuhlobo nokusingqongileyo kwaye kunceda ishishini eliluhlaza. Njengoko ishishini linika ingqalelo ngakumbi kulondolozo, iintonga zokuwelda zibonelela ngezisombululo ezisebenzayo zokufezekisa ukusebenza kunye neenjongo zokusingqongileyo.
I-Ni307-2intonga yokuweldalukhetho olukhethwayo kwiingcali ezifuna izisombululo zokuwelda ezinokuthenjwa, eziguquguqukayo nezisebenzayo.
