Kuwotcherera kwa arc pansi pamadzichitoliro chachitsulo chozunguliraamagwiritsa ntchito waya wowotcherera mosalekeza ngati ma elekitirodi ndi zitsulo zodzaza. Pogwira ntchito, malo owotcherera amakutidwa ndi wosanjikiza wa granular flux. The lalikulu-diameter spiral chubu arc amayaka pansi pa flux wosanjikiza, kusungunula mapeto a kuwotcherera waya ndi gawo la maziko zitsulo. Pansi pa kutentha kwa arc kuti apange weld, kutuluka kwapamwamba kumasungunula slag ndikuchita metallurgically ndi zitsulo zamadzimadzi. Silagi yosungunuka imayandama pamwamba pa dziwe losungunuka lachitsulo. Kumbali imodzi, imatha kuteteza chitsulo chowotcherera, kuteteza kuipitsidwa kwa mpweya, ndikupanga zochitika zakuthupi ndi zamankhwala ndi chitsulo chosungunula, kuwongolera kapangidwe kake ndi magwiridwe antchito achitsulo chowotcherera. Kumbali inayi, imathanso kupanga chitsulo chowotcherera Pang'onopang'ono kuziziritsa. Kuwotcherera kwa arc pansi pamadzi kumatha kugwiritsa ntchito kuwotcherera kokulirapo, ndipo zabwino zake ndizomwe zimakhala zabwino komanso kuthamanga kwambiri. Choncho, makamaka oyenera kuwotcherera lalikulu m'mimba mwake mozungulira zitsulo mapaipi. Ambiri aiwo amatengera kuwotcherera makina, komwe kwagwiritsidwa ntchito kwambiri pakuwotcherera kwa chitsulo cha kaboni, chitsulo chochepa cha aloyi, ndi chitsulo chosapanga dzimbiri.

High-frequency kuwotcherera ndi njira yolimba-gawo yokana kuwotcherera. Kuwotcherera kwanthawi yayitali kumatha kugawidwa kukhala kuwotcherera kwanthawi yayitali komanso kuwotcherera kwapang'onopang'ono kutengera momwe ma frequency apamwamba amapangira kutentha mu workpiece. Mukalumikizana ndi kuwotcherera kwanthawi yayitali, ma frequency apamwamba kwambiri amaperekedwa ku chogwirira ntchito kudzera pamakina olumikizana ndi workpiece. Panthawi yowotcherera ma frequency apamwamba kwambiri, magetsi othamanga kwambiri amatulutsa mphamvu yamagetsi mu chogwirira ntchito kudzera pakulumikizana kwa koyilo yolowera kunja kwa chogwirira ntchito. Kuwotcherera kwanthawi yayitali ndi njira yapadera kwambiri yowotcherera, ndipo zida zapadera ziyenera kukhala ndi zida malinga ndi zomwe zimapangidwa. High zokolola, kuwotcherera liwiro akhoza kufika 30m/mphindi. Pogwiritsa ntchito kutentha kolimba ngati gwero la mphamvu, kutentha kwamphamvu komwe kumapangidwa ndi mafunde apamwamba kwambiri mu workpiece kumagwiritsidwa ntchito panthawi yowotcherera kutenthetsa pamwamba pa malo otsekemera a workpiece kuti asungunuke kapena pafupi ndi pulasitiki, ndiyeno kusokoneza mphamvu. amagwiritsidwa ntchito (kapena osagwiritsidwa ntchito) kuti akwaniritse mgwirizano wazitsulo.
