ukunikezwa kokushisa okuqhubekayo okukhiqizwa yi-flat output current yomshini wokushisela imvamisa ephakathi kwenza izinga lokushisa le-nugget likhuphuke ngokuqhubekayo. Ngesikhathi esifanayo, ukulawulwa okunembile kwe-slope yamanje ekhuphukayo kanye nesikhathi ngeke kubangele i-spatter ngenxa yokushisa kokushisa kanye nesikhathi sokukhuphuka kwamanje esingalawuleki.
UMA i-inverter spot welder inomshini wokushisela oyisicaba, oqinisekisa ukusebenza kahle okuphezulu nokunikezwa okuqhubekayo kokushisa okushiselayo. Futhi isikhathi sokusebenza kwamandla sifushane, sifinyelela izinga le-ms, okwenza indawo ye-welding ethinteke ukushisa ibe yincane, futhi amalunga e-solder akhiwe kahle.
imvamisa yokusebenza ephezulu (imvamisa engu-1-4KHz) yomshini wokushisela imvamisa emaphakathi, ukunemba kokulawula impendulo izikhathi ezingama-20-80 zomshini wokushisela indawo we-AC ojwayelekile kanye nomshini wokushisela wendawo yokulungisa yesibili, kanye nokunemba kokulawula okukhiphayo nakho phezulu kakhulu.
ukonga amandla. Ngenxa yokusebenza kahle kokushisa okuphezulu, i-welding transformer encane kanye nokulahlekelwa okuncane kwensimbi, umshini wokushisela inverter ungonga amandla angaphezu kuka-30% kunomshini wokushisela indawo ye-AC kanye nomshini wokushisela wendawo wokulungisa lapho ushisela isiqeshana sokusebenzela esifanayo.
Isetshenziselwa ukushisela amabala nokushisela amantongomane ensimbi enamandla amakhulu kanye nensimbi eyakhiwe eshisayo embonini yokukhiqiza izimoto, ukushisela indawo kanye ne-multi-point projection welding yepuleti lensimbi eline-carbon ephansi, ipuleti lensimbi engagqwali, ipuleti le-aluminium kanye i-wire, i-resistance brazing kanye ne-spot welding ye-copper wire embonini kagesi yamandla aphezulu naphansi, i- silver spot welding, i-copper plate brazing, inhlanganisela yendawo yesiliva yokushisela, njll.
IMP: Imvamisa yokulungiswa kufanele inqunywe ngokuya ngokusetshenziswa kwe-spot welder nendawo yokukhiqiza, futhi kuvame ukutuswa ukwenza ukulungiswa kanye ngenyanga.
A: Ukukhethwa kokunikezwa kwamandla omshini wokushisela indawo kufanele kunqunywe ngokuvumelana namandla emishini kanye nendawo yokusetshenziswa ukuze kuqinisekiswe ukuthi okokusebenza kungasebenza ngokujwayelekile.
IMP: Ama-Spot welders adinga ukusetshenziswa kwezingilazi zokuzivikela, amagilavu, namanye amathuluzi okuphepha ukuze kugcinwe abaqhubi bephephile.
A: Ukunikezwa kwamandla kufanele kuxhunywe ngokuya ngezidingo zikagesi namazinga okuphepha emishini.
A: Impilo yesevisi yomshini wokushisela indawo incike ezintweni ezifana nekhwalithi yemishini, ukugcinwa kanye nemvelo yokusebenzisa, ngokuvamile phakathi kweminyaka engu-5-10.
A: Isivinini sokushisela sincike kusayizi kanye yinkimbinkimbi yephrojekthi yokushisela futhi ngokuvamile izikhathi eziningana ngomzuzwana.
