The preheating kung'anima kuwotcherera ndondomeko: pamaso mosalekeza kung'anima kuwotcherera imayimitsidwa, ndimakina owotchereraimatenthedwa ndi chitsulo cholimbitsa.Gwirani chitsulo pansagwada ya chowotcherera matako.Mphamvu ikatsegulidwa, mapeto otseguka amagwiritsidwa ntchito kuti mapeto a zitsulo aziphwanyidwa ndi kupanikizika pang'ono, ndiyeno kupatukana, kotero kuti nthawi zonse amalekanitsidwa ndi kulira, nthawi zonse akuphwanyidwa, chifukwa cha kukana kwa chopinga chophwanyidwa ndi kukana kwakunja kwazitsulo zachitsulo.Malo owotcherera amatenthedwa, ndipo akatsegulidwa, nthawi yowunikira imapangidwa.Kubwerezedwa mobwerezabwereza pamwamba, kutentha kumachepetsedwa pang'onopang'ono, ndipo njira yotenthetsera ikuchitika.Pambuyo pa kutentha, kung'anima ndi kukhumudwa kumayimitsidwa, ndipo njira ziwirizi ndizofanana ndi kuwotcherera kwamoto kosalekeza.Mukatengera mtundu wa un2-150 kapena un17-150-1 mtundu wa butt wowotcherera kuti muyimitse kuwotcherera kwazitsulo zazikulu m'mimba mwake, m'pofunika kutengera njira yocheka kapena kudula gasi kuti muyimitse chithandizo chakumapeto kwa chitsulo chachitsulo. ;ndiye tengerani njira yowotcherera yowotcherera kung'anima, ma hydraulic flash pair Wowotcherayo azitsatira zofunikira izi: kuwunikira kuzikhala kolimba komanso kokhazikika;zongopeka zidzakwezedwa;kusintha kolondola kudzapangidwa ndipo poyambira ndi poyimitsa ndondomeko iliyonse idzayendetsedwa bwino.

Kugwiritsa ntchito chowotcherera matako kuyenera: (1) Chowotcherera matako chiyenera kuikidwa m’nyumba kapena m’shedi yochitiramo mvula, ndipo chiyenera kukhala ndi nthaka yolimba kapena ziro.Pamene zowotcherera matako angapo zimakonzedwa mbali ndi mbali, mtunda pakati pawo suyenera kukhala wochepera 3m, ndipo uyenera kupatulidwa ndi gululi ndi gawo losiyana, ndipo wophwanya dera ayenera kupatulidwa.(2) Musanayambe kuwotcherera, ziyenera kuwunikiranso ndikutsimikiziridwa: makina oponderezedwa a welder ayenera kukhala okhazikika, chotchinga chizikhala chokhazikika, komanso kuthamanga kwa mpweya ndi ma hydraulic system sayenera kutayikira.(3) Pamaso kuwotcherera, voteji yachiwiri idzasinthidwa molingana ndi gawo la chitsulo chowotcherera, ndipo chitsulo chachitsulo chopitirira m'mimba mwake mwa chitsulo chosungunula sichidzawotchedwa.(4) Malo opumira ndi electrode ya woyendetsa dera adzakulitsidwa pa nthawi, ndipo bolt yachiwiri yolumikizira dera idzayimitsidwa monga momwe idakonzedwera.Kutentha kwa madzi ozizira sikuyenera kupitirira 40 °, ndipo kusamutsidwa kuyenera kusinthidwa malinga ndi kutentha.(5) Powotcherera zitsulo zazitali, pamafunika kukhala ndi mabulaketi.(6) Malo owala adzapatsidwa chododometsa, ndipo antchito okhudzana ndi kuwotcherera sadzalowa.(7) Powotchera m'nyengo yozizira, kutentha sikuyenera kutsika 8 °.Pambuyo pa homuweki, madzi ozizira mu makina ayenera kutha.
