Imishini yokushisela kagesi isebenzisa amandla kagesi ukuguqula ngokushesha amandla kagesi abe amandla okushisa. Ugesi uvame kakhulu. Imishini yokushisela kagesi ilungele ukusebenza endaweni eyomile futhi ayidingi izidingo eziningi kakhulu. Zisetshenziswa kabanzi emikhakheni ehlukahlukene ngenxa yosayizi wazo omncane, ukusebenza okulula, ukusetshenziswa okulula, isivinini esisheshayo kanye ne-weld eqinile ngemuva kokushisela, ikakhulukazi kwimikhiqizo edinga amandla aphezulu, Izinto ezifanayo zensimbi (noma izinsimbi ezahlukahlukene zingaxhunywa, kepha izindlela zokushisela zihlukile) zingaxhunywa unomphela. Ngemuva kokwelashwa kokushisa, i-weld inamandla afanayo nensimbi eyisisekelo futhi inokubekwa uphawu okuhle, okuxazulula izinkinga zokubekwa uphawu namandla okwenziwa kweziqukathi zokugcina igesi noketshezi. 2, Ububi bomshini wokushisela kagesi: ngesikhathi sokusebenzisa umshini wokushisela kagesi, kuzokwakhiwa insimu ethile kazibuthe ezungeze umshini wokuwelda, futhi imisebe izokhiqizwa kokuzungezile ngesikhathi somlilo we-arc. Kukhona i-infrared, i-ultraviolet nezinye izinhlobo zokukhanya ku-arc, kanye nezinto eziyingozi ezifana nensimbi yensimbi nentuthu. Ngakho-ke, kufanele kuthathwe izinyathelo zokuzivikela ezanele ngesikhathi sokusebenza. Ukushisela akulungele ukushisela insimbi ephezulu yekhabhoni. Ngenxa ye-crystallization, ukuhlukaniswa kanye ne-oxidation yensimbi ye-weld, ukusebenza kwe-welding kwekhabhoni yensimbi ephezulu akukuhle, futhi kulula ukuqhekeka ngemuva kokushisela, okuholela ekuqhekekeni okushisayo nemifantu ebandayo. Insimbi yekhabhoni ephansi inokusebenza okuhle kwe-welding, kepha kufanele futhi kusetshenziswe kahle kule nqubo. Ukucekelwa phansi nokuhlanzwa kuyasinda. Kwesinye isikhathi ukuqhuma kwe-slag, ama-pores, ama-undercuts kanye nokunye ukukhubazeka kuzovela ku-weld, kepha ukusebenza okufanele kuzonciphisa ukuvela kwamaphutha.

Okwamanje namandla kagesi ancishiswa yisiguquli esiyizigaba ezintathu, esilungiswa yi-thyristor element, futhi okukhiphayo kwamanje kulawulwa ngokushintsha isigaba se-trigger angle se-thyristor. Khipha isignali yamanje kusuka ku-shunt ekugcineni kokukhipha kwe-DC kwesilungisi njengesignali yempendulo engeyinhle yamanje. Njengoba ukukhishwa kwamanje kwe-DC kukhuphuka, impendulo engemihle nayo iyanda, i-thyristor conduction angle iyancipha, futhi okukhiphayo njengamanje namandla kuncipha, ukuze kutholakale izici zangaphandle ezincishisiwe. Isifunda sokugxila sandisa okukhiphayo okwamanje lapho amandla okukhipha engaphansi kuka-15V, ikakhulukazi uma kwenzeka isifunda esifushane, kwakheka izici zangaphandle zokuhudula kwangaphandle, ukuze i-electrode kungabi lula ukunamathela. Isifunda esitelekayo se-arc sonyusa amandla kagesi anikeziwe ngesikhathi esifushane phakathi kwesiteleka ngasinye se-arc, ukuze i-arc yesiteleka yamanje ibe nkulu futhi kulula ukuqala
