Zida zilizonse zimayenera kumvetsetsa zofunikira zomwe mungagwiritse ntchito kale komanso mutatha kugwiritsa ntchito zidazo, kuti zisangotsimikizira kuti zida za zidazo, koma onetsetsani kuti mwachitapo kanthu motetezeka. Tonsefe tikudziwa kuti zida zaluso zamphamvu zimathandiza kuti pakhale msewu womanga msewu, ndipo ntchito yake imakhudza mwachindunji malo monga misewu monga misewu. Kuti tiwonetsetse bwino, tiyenera kulabadira kwambiri pankhani zinayi mukamagwiritsa ntchito.

Tikamagwiritsa ntchito zida zophatikizika, tifunika kusamala kwambiri ndi zinthu zinayi zotsatirazi: 1. Asanapatsidwe mankhwala, zida ziyenera kuwona ngati malo a valavu iliyonse ndi yolondola. Pulambala wowonda wowonjezedwa ku zida zophatikizidwa kuti akwaniritse kutentha kwa 160 ~ 180 ℃. Kwa mayendedwe ataliatali kapena nthawi yayitali yogwira ntchito, chipangizo chotenthetsera chitha kugwiritsidwa ntchito poti amakutira, koma sichingagwiritsidwe ntchito ngati ng'anjo yosungunuka. 2. Mukamatenthetsa phula mu zida zophatikizidwa ndi Burner, kutalika kwa phula kuyenera kupitirira mumbewu la chipinda choyaka, apo ayi chipinda cha kuyaka chidzawotchedwa. 3. Zipangizozo sizingadzadzazidwa kwambiri, ndipo chipewa chamafuta chingapangidwire mwamphamvu kuti mupewe phula ku kusefukira. 4. Galimoto iyi ili ndi zowongolera ziwiri, kutsogolo ndi kumbuyo. Mukamagwiritsa ntchito kuwongolera kutsogolo, muyenera kusintha njira yosinthira. Pakadali pano, kutonthoza kwammbuyo kumatha kuwongolera kukwera ndikugwa kwa mphuno.
