201 Insimbi Engagqwali
Okuqukethwe kwethusi: J4>J1>J3>J2>J5.
Okuqukethwe kwekhabhoni: J5>J2>J3>J1>J4.
Ukuhlelwa kobulukhuni: J5, J2>J3>J1>J4.
Ukuhleleka kwamanani kusukela phezulu kuya phansi yilokhu: J4>J1>J3>J2, J5.
I-J1（Mid Copper）: Okuqukethwe kwekhabhoni kuphakeme kancane kune-J4 kanti okuqukethwe kwethusi kuphansi kune-J4. Ukusebenza kwayo kokucubungula kungaphansi kwe-J4. Ifaneleka emikhiqizweni evamile yokudweba engajulile kanye neyokudweba okujulile, njengebhodi lokuhlobisa, imikhiqizo yenhlanzeko, isinki, ipayipi lomkhiqizo, njll.
J2, J5: Amashubhu okuhlobisa: Amashubhu okuhlobisa alula asalungile, ngoba ubulukhuni buphezulu (bobabili bungaphezu kuka-96°) futhi ukupholisha kuhle kakhulu, kodwa ishubhu eliyisikwele noma ishubhu eligobile (90°) livame ukuqhuma.
Ngokuphathelene nepuleti eliyisicaba: ngenxa yobunzima obuphezulu, ubuso bebhodi buhle, kanye nokwelashwa kobuso okufana
Ukuqandisa, ukupholisha kanye nokufaka iplasta kuyamukeleka. Kodwa inkinga enkulu inkinga yokugoba, ukugoba kulula ukukuphula, kanye nomsele kulula ukuwuqhumisa. Ukunwebeka okubi.
I-J3 (Ithusi Eliphansi): Ifanele amashubhu okuhlobisa. Ukucubungula okulula kungenziwa kuphaneli yokuhlobisa, kodwa akunakwenzeka ngobunzima obuncane. Kukhona impendulo yokuthi ipuleti lokugunda ligobile, futhi kukhona umthungo wangaphakathi ngemva kokuphuka (i-titanium emnyama, uchungechunge lwepuleti lombala, ipuleti lokusinkisha, liphukile, ligoqwe ngomthungo wangaphakathi). Izinto zesinki zizanyiwe ukugoba, ama-degree angu-90, kodwa ngeke ziqhubeke.
I-J4（Ithusi Eliphezulu）: Iwukuphela okuphezulu kochungechunge lwe-J. Ifanele izinhlobo ezincane ze-engeli yemikhiqizo yokudweba ejulile. Iningi lemikhiqizo edinga ukuqoqwa kukasawoti ojulile kanye nokuhlolwa kokufuthwa kukasawoti izoyikhetha. Isibonelo, amasinki, izitsha zasekhishini, imikhiqizo yokugezela, amabhodlela amanzi, amaflaski e-vacuum, amahinji eminyango, amaketanga, njll.
