Faʻamatalaga: O le J707Ni o se eletise uʻamea maualuga-maualalo faʻatasi ma le paʻu sodium maualalo-hydrogen.Fa'aaoga le DCEP (fa'atonu eletise eletise) ma e mafai ona uelo i tulaga uma.O u'amea teuina e iai mea fa'ainisinia lelei.Pe a faatusatusa i le eletise J707, o le vaega autu o le J707Ni o le maualalo o le vevela o le malosi ma le faʻafefeteina ua matua faʻaleleia.
Talosaga: Faʻaaogaina mo le faʻapipiʻiina o fausaga uʻamea maualuga-maualalo o le malosi tutusa, e pei o le 14MnMoVB, WEL-TEN70 ma Iapani HW56 ma isi fausaga uʻamea maualuga-maualalo.

Fa'aaliga:
1. E tatau ona tao le electrode mo le 1 itula i le 350 ~ 380 ℃ aʻo leʻi faʻaogaina le faʻaogaina;
2. E taua tele le fa'amamāina o le ea, fua o le suau'u, vai, ma mea leaga i luga o vaega uelo a'o le'i u'uina;
3. Fa'aaoga le fa'agaioiga pu'upu'u pe a uelo.O le ala uelo vaapiapi e talafeagai.
