Pofuna kuonetsetsa kukula nugget ndi solder olowa mphamvu ya pafupipafupi sing'angamakina kuwotcherera malo, nthawi yowotcherera ndi kuwotcherera kwapano kumatha kuthandizirana mkati mwamitundu ina. Kuti mupeze mgwirizano wa solder ndi mphamvu inayake, mfundo ziwiri zotsatirazi nthawi zambiri zimatheka.
Ndiko kuti, nthawi yayikulu komanso yaifupi (yotchedwa hard standard), komanso nthawi yaying'ono komanso yayitali (yotchedwa soft standard) ingagwiritsidwenso ntchito. Gwiritsani ntchito choyezera cholimba kapena choyezera chofewa, kutengera zakuthupi ndi makulidwe achitsulo ndi mphamvu ya welder yomwe imagwiritsidwa ntchito. Pakalipano ndi nthawi yofunikira pakuwotcherera zitsulo ndi makina opangira malo ali ndi mfundo, zomwe ziyenera kugwiritsidwa ntchito ngati chitsogozo pochigwiritsa ntchito. Pofuna kuonetsetsa kuwotcherera khalidwe, kufunika kwa malo kuwotcherera maelekitirodi makina ambiri zimaonekera mfundo zotsatirazi:
1. Kuthamanga kwa elekitirodi wapakatikati pafupipafupi malo kuwotcherera makina zimakhudza kwambiri kukana okwana R pakati maelekitirodi awiri. Pamene kuthamanga kwa electrode kumawonjezeka, R imachepa kwambiri. Mwa njira iyi, kuwotcherera panopa kumangowonjezera pang'ono, ndipo chikokacho chimakhala chifukwa cha kuchepa kwa R. Kutentha kwa kutentha komwe kumachitika chifukwa cha kutentha kwakukulu.
2. Mphamvu zazitsulo zogulitsira zimachepa nthawi zonse pamene kuthamanga kwa kuwotcherera kumawonjezeka. Njira yothetsera vutoli ndikuwonjezera kuthamanga kwa kuwotcherera. Nthawi zambiri, pamene m'mimba mwake wa ma elekitirodi mapeto nkhope ya malo kuwotcherera makina ndi mosalekeza, kukana workpiece zimadalira resistivity ake.
3. Zitsulo zokhala ndi mphamvu zowonongeka zimakhala ndi mphamvu zowonongeka zamagetsi (monga zitsulo zosapanga dzimbiri) ndipo zitsulo zokhala ndi mphamvu zochepa zimakhala ndi magetsi abwino (monga aluminiyamu alloys).
Mwa njira iyi, resistivity sichingodalira mtundu wa chitsulo, komanso pamtundu wa kutentha kwa kutentha, njira yopangira ndi kutentha kwachitsulo. Kuthamanga kwa electrode kotereku kumakhudza kwambiri kukana kwathunthu R pakati pa maelekitirodi awiri. Pamene kuthamanga kwa electrode kumawonjezeka, R imachepa kwambiri, koma kuwonjezeka kwa kuwotcherera panopa sikuli kwakukulu. Sizingakhudze kukana chifukwa cha kuchepa kwa R. Kutentha kwa kutentha kumachepetsedwa. Chifukwa chake, mphamvu zowotcherera zimfundo zamakina apakati-kawirikawiri zimachepa nthawi zonse pamene mphamvu yowotcherera ikuwonjezeka. Yankho lake ndi kuonjezera kuwotcherera panopa pamene kuwonjezera kuwotcherera kuthamanga.
