MALANGIZO:
1. Ma electrode ayenera kuphikidwa pansi pa 350-400℃ kwa ola limodzi musanawotchetse, kuyikidwa mu chidebe chotenthetsera ndikuyika nthawi yomweyo akafunika.
2. Madontho omwe ali pa cholumikizira ngati dzimbiri ayenera kuchotsedwa, ndipo cholumikiziracho chiyenera kutenthedwa mpaka madigiri 200 Celsius.
3. Chopoperacho chimatha kutenthedwa pansi pa 600-650℃ pambuyo powotcherera kuti athetse kupsinjika kwamkati.
