Fa'amatalaga: O le J707 o se eletise u'amea maualuga-maualalo fa'atasi ma le pa'u sodium maualalo-hydrogen.Fa'aaoga le DCEP (fa'atonu eletise eletise lelei), ma e mafai ona uelo i tulaga uma.Pe a manaʻomia, e mafai ona faʻamafanafanaina faʻamaʻi aʻo leʻi faʻapipiʻiina ma faʻafefe pe a uma ona faʻafefe.

Fa'aoga: Fa'aaogaina mo le ueloina 15MnMoV, 14MnMoVB, 18MnMoNb ma isi fausaga u'amea maualalo.O le fausaga uelo e mafai ona galue i lalo o le tulaga o le uelo poʻo le faʻafefe (500 ~ 650 ℃).

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.
