Enqubweni yokushisela i-intermediate frequency spot welder, ukumelana kwakhiwe ukumelana nokuxhumana phakathi kokushisela, ukumelana nokuxhumana phakathi kwama-electrode nama-welds kanye nokumelana kwama-welds ngokwawo. Njengoba izinga lokushisa likhuphuka, ubukhulu bokumelana bushintsha njalo.
Ngesikhathi sokushisela, umehluko wengcindezi ye-electrode, yamanje kanye nezinto ezizoshiselwa konke kuthinta ushintsho olunamandla lokumelana. Lapho izinto ezahlukene zensimbi zishiselwe, ukumelana okuguquguqukayo kushintsha ngokuhlukile. Ekuqaleni kwe-welding, insimbi endaweni ye-welding ayincibiliki kodwa ishisa ngaphambili, futhi ukumelana nokuxhumana kwehla ngokushesha. Njengoba izinga lokushisa likhuphuka, ukumelana nokunyuka, kuyilapho ukumelana kuncipha ngenxa yokwanda kwendawo yokuxhumana ebangelwa ukushisa, lapho ukwanda kwe-resistantivity kubusa, ngakho-ke ijika likhuphuka.
Lapho izinga lokushisa lifinyelela inani elibalulekile, ukukhula kwe-resistivity kuncipha futhi okuqinile kuba uketshezi. Ngenxa yokwanda kwendawo yokuxhumana ngenxa yokuthambisa ukushisa, ukumelana kuncipha, ngakho ijika liyancipha futhi. Okokugcina, ngenxa yokuthi inkambu yezinga lokushisa kanye nenkambu yamanje kungena esimweni sokuzinza, ukumelana okuguquguqukayo kuvame ukuzinza.
Ngokombono wedatha yokumelana, ushintsho olusuka ku-180μΩ ekuqaleni kokushisela luye cishe ku-100μΩ ekugcineni lukhulu kakhulu. Ngokombono, ijika lokumelana eliguquguqukayo lihlobene kuphela nezinto ezibonakalayo, futhi linezici zendawo yonke. Kodwa-ke, ekulawuleni kwangempela, ngenxa yokuthi ukumelana kunzima ukukubona, kunzima ukulawula ngokusho koshintsho lokumelana. Ukutholwa komshini wokushisela kulula, uma ijika lokumelana eliguqukayo liguqulwa libe ijika lamanje eliguquguqukayo, kulula kakhulu ukulisebenzisa. Nakuba ijika lamanje eliguquguqukayo lihlobene namandla kanye nezici zomthwalo we-intermediate frequency spot welder, lapho izimo zehadiwe (i-intermediate frequency spot welder) ziqinisekile, ijika lamanje eliguqukayo kanye nejika lokumelana eliguqukayo kunemithetho ehambisanayo.
