1. Lithupa li fanoa ka likhoele tse otlolohileng tse lokelang ho sebetsoa kapa ho bōptjoa ke moreki hore e be likarolo tsa ho qetela.Ho theha ho etsoa pele lilemo li thatafala.Ho sebetsa ka mechine hangata ka mor'a ho thatafala.Lisebelisoa tse tloaelehileng li kenyelletsa:
▪ Li-bearings le matsoho a lisenthimithara tse hlokang tlhokomelo e fokolang
▪ Likarolo tsa sebopeho sa "resistance welding gun".
▪ Lithupa tsa mantlha le lintho tse kentsoeng ka hlobo ea ente le litšepe
▪ Mohokahanyi oa indasteri ea puisano

2. Li-bar li boetse li fanoe ka likhoele tse otlolohileng, empa ntle le karolo e pota-potileng, lisekoere, khutlonnetsepa le likhutlo tse tharo le tsona li atile haholo. Ts'ebeliso e tloaelehileng e kenyelletsa:
▪ Boto e thibelang ho roala
▪ Liporo tse tataisang le litšepe tsa libese
▪ Lifastening tse nang le likhoele
▪ Ho hana ho cheseletsa

3. Li-tubes li na le letoto la motsoako oa bophara / lebota la botenya, ho tloha ho likarolo tse entsoeng ka marako a tšesaane haholo, li-tubes tse tšesaane tse huloang ka ho toba, le li-tubes tse teteaneng tse sebetsang ka ho chesa.Lisebelisoa tse tloaelehileng ke tse latelang:
▪ Liphaephe tse matla, tse matla haholo, litataiso tsa maqhubu le li-pitot tube bakeng sa liletsa
▪ Li-bearings le li-pivot tsa lisebelisoa tsa ho theola sefofane
▪ Boroko ba nako e telele ba ho phunya lihlooho tse tharo
▪ Mohaho o sa keneleng khatellong oa lisebelisoa tse nepahetseng tsa khoheli le lisebelisoa tse ling

Tšebeliso ea bohlokoa ea lithupa, mekoallo le li-tubes ke bakeng sa lihlahisoa tse sebelisetsoang ho tjheseletsa ho hanyetsa.Koporo ea Beryllium e kopana le tlhokahalo ena ea indasteri ka ho thatafala ha eona le conductivity ho netefatsa ho nepahala ha likarolo tsa meralo le ho tšoarella ha li-electrode.Ho bonolo ho e etsa ka ho kobeha le ho sebetsa ka mochine, hape e fokotsa litšenyehelo tsa ho hanyetsa welding.
