MALANGIZO:
1.Ma electrode ayenera kuphikidwa pansi pa 350-400 ℃ kwa ola limodzi musanawotchere, kuyika muzitsulo zotsekemera ndikuyika mwamsanga pamene akufunikira.
2. Madontho pa weld ngati dzimbiri ayenera kuchotsedwa, ndipo weld ayenera preheated mpaka 200 ℃.
3.Weld akhoza kupsya mtima pansi pa 600-650 ℃ pambuyo kuwotcherera kuti athetse nkhawa zamkati.
