Nkhaniyi ikuyankha funso ngati sing'anga pafupipafupi inverter malo kuwotcherera makina zotuluka pulsed mwachindunji panopa (DC). Kumvetsetsa momwe magetsi amagwirira ntchito ndikofunikira pakuwunika kuyenerera kwa makina owotcherera pazinthu zinazake ndikuwongolera njira yowotcherera.
- Mfundo Yogwiritsira Ntchito: Makina opangira ma frequency inverter spot kuwotcherera amagwira ntchito posintha zolowera zapano (AC) kukhala zotuluka mwachindunji (DC) kudzera pagawo la inverter. Dera la inverter limaphatikizapo zinthu monga zosinthira ndi zosefera zomwe zimawongolera mawonekedwe otuluka.
- Pulsed Operation: Nthawi zambiri, makina owotcherera apakati pafupipafupi amapangidwa kuti azipereka ma pulsed current panthawi yowotcherera. Pulsed current imatanthawuza mawonekedwe a mafunde pomwe mafundewa nthawi ndi nthawi amasinthana pakati pa milingo yokwera ndi yotsika, ndikupanga kugunda kwamphamvu. Kuthamanga kumeneku kungapereke ubwino wambiri, kuphatikizapo kuchepetsa kutentha, kuwongolera njira zowotcherera, ndi kuchepetsa kupotoza.
- Chigawo cha Direct Current (DC): Ngakhale makina owotcherera apakati a frequency inverter amatha kutulutsa ma pulsed current, alinso ndi gawo lachindunji (DC). Chigawo cha DC chimaonetsetsa kuti kuwotcherera kokhazikika komanso kumathandizira kuti kuwotcherera kuchitike. Kukhalapo kwa gawo la DC kumathandizira kukhazikika kwa arc, kumathandizira kuti ma elekitirodi akhale ndi moyo wautali, komanso kumathandizira kulowa kwa weld mosasinthasintha.
- Linanena bungwe Control: sing'anga pafupipafupi inverter malo kuwotcherera makina amalola kusintha zimachitika pafupipafupi, zimachitika nthawi, ndi matalikidwe panopa, kupereka ulamuliro pa ndondomeko kuwotcherera. Magawo osinthikawa amathandizira ogwiritsa ntchito kukhathamiritsa mikhalidwe yowotcherera potengera zinthu, masanjidwe olumikizana, ndi mawonekedwe omwe amafunidwa.
Makina owotcherera apakati pafupipafupi ma frequency inverter amatha kutulutsa pompopompo ndi gawo lachindunji (DC). Ma pulsed current amapereka maubwino potengera kuwongolera kwa kutentha ndi mtundu wa weld, pomwe gawo la DC limatsimikizira mawonekedwe okhazikika arc. Popereka kusinthasintha pakusintha magawo a pulse, makina owotcherera amathandizira ogwiritsa ntchito kuti akwaniritse kuwongolera bwino pakuwotcherera. Kumvetsetsa mawonekedwe a makinawo ndikofunikira pakusankha magawo oyenera kuwotcherera ndikukulitsa luso la kuwotcherera komanso kuchita bwino.
