Pankhani ya kuwotcherera, chinthu chabwino kwambiri nthawi zambiri chimatha kuwonjezera ndalama zosafunikira, nthawi yocheperako komanso kutayika kwa zokolola - makamaka ngati muli ndi mfuti yayikulu kwambiri ya MIG kuti mugwiritse ntchito.Tsoka ilo, anthu ambiri amakhulupirira lingaliro lolakwika: loti mukufunika mfuti ya MIG yomwe ili yokwera kwambiri yomwe mukuyembekezera kutenthetsa (mwachitsanzo, mfuti ya 400-amp pakugwiritsa ntchito 400-amp).Zimenezo si zoona.M'malo mwake, mfuti ya MIG yomwe imapereka mphamvu yochulukirapo kuposa momwe mumafunira imalemera kwambiri ndipo imatha kukhala yosasunthika, zomwe zimapangitsa kuti zisakhale zomasuka kuyenda mozungulira ma weld.Mfuti zapamwamba kwambiri za MIG zimawononganso ndalama zambiri.
Kusankha mfuti "yambiri" kumatha kukulitsa kutopa ndikuchepetsa zokolola zanu.Mfuti yabwino ya MIG imagunda bwino pakati pa zomwe pulogalamuyo ikufuna, komanso kukula ndi kulemera kwa mfuti ya MIG.
Chowonadi ndichakuti, chifukwa mumawononga nthawi ndikusuntha magawo, kuwagwira ndikuchita zina zomwe zisanachitike komanso zowotcherera, simumawotcherera mosalekeza kuti mufikire ntchito yayikulu yamfuti ya MIG.M'malo mwake, nthawi zambiri zimakhala bwino kusankha mfuti yopepuka, yosinthika kwambiri yomwe ikukwaniritsa zosowa zanu.Mwachitsanzo, mfuti ya MIG yomwe ili ndi ma amps 300 imatha kuwotcherera pa ma amps 400 ndi kupitilira apo - kwakanthawi kochepa - ndikuchita ntchito yabwino.
Mavoti amfuti adafotokozera
Ku United States, bungwe la National Electrical Manufacturers Association, kapena NEMA, limakhazikitsa njira zoyezera mfuti za MIG.Ku Europe, miyezo yofananira ndiudindo wa Conformité Européenne kapena European Conformity, yotchedwanso CE.
Pansi pa mabungwe onse awiri, mfuti za MIG zimalandira mlingo womwe umawonetsa kutentha pamwamba pomwe chogwirira kapena chingwe chimakhala chofunda movutikira.Izi, komabe, sizikuwonetsa pomwe mfuti ya MIG ingawononge kapena kulephera.
Kusiyana kwakukulu kuli pakugwira ntchito kwa mfuti.Opanga ali ndi mwayi wosankha mfuti zawo pa 100-, 60- kapena 35 peresenti ya ntchito.Pazifukwa izi, pangakhale kusiyana kwakukulu poyerekeza zinthu zosiyanasiyana za opanga mfuti za MIG.
Kuzungulira kwa ntchito ndi kuchuluka kwa nthawi yokhazikika mkati mwa mphindi 10.Mmodzi wopanga mfuti wa MIG atha kupanga mfuti ya MIG ya 400-amp yomwe imatha kuwotcherera pa 100 peresenti, pomwe wina amapanga mfuti ya MIG yomwe imatha kuwotcherera 60 peresenti yokha.Mu chitsanzo ichi, mfuti yoyamba ya MIG imatha kuwotcherera mosalekeza kwa mphindi 10, pomwe yomalizayo imatha kuwotcherera kwa mphindi zisanu ndi chimodzi.
Musanasankhe mfuti ya MIG yogula, ndikofunika kuunikanso kuchuluka kwa ntchito kwa malondawo.Mutha kupeza izi m'mabuku azinthu kapena patsamba la opanga.
Kodi mumagwira ntchito bwanji?
Kutengera kufotokozera kwa mfuti pamwambapa, ndikofunikiranso kuti muganizire za nthawi yomwe mumathera pakuwotcherera musanasankhe mfuti ya MIG.Onani kuchuluka kwa nthawi yomwe mumathera pakuwotcherera pakadutsa mphindi 10.Mutha kudabwa kupeza kuti nthawi yapakati pa arc nthawi zambiri imakhala yosakwana mphindi 5.
Kumbukirani kuti kuwotcherera ndi mfuti ya MIG yovotera ma amps 300 kungadutse mphamvu yake yowerengera ngati mutagwiritsa ntchito ma amps 400 ndi 100 peresenti ya ntchito.Komabe, ngati mutagwiritsa ntchito mfuti yomweyo kuwotcherera ma amps 400 ndi 50 peresenti ya ntchito, iyenera kugwira ntchito bwino.Momwemonso, ngati mutakhala ndi pulogalamu yomwe imafunikira kuwotcherera chitsulo chokhuthala kwambiri (ngakhale ma amps 500 kapena kuposerapo) kwakanthawi kochepa, mutha kugwiritsa ntchito mfuti yomwe ili ndi ma amps 300 okha.
Monga lamulo, mfuti ya MIG imakhala yotentha kwambiri ikapitilira kutentha kwake kwanthawi zonse.Ngati mukuwona kuti mukuwotchera nthawi yayitali pafupipafupi, muyenera kuganizira zowotcherera pamalo ocheperako kapena kusinthana ndi mfuti yapamwamba kwambiri.Kuchuluka kwa kutentha kwa mfuti ya MIG kungayambitse kufooka kwa malumikizidwe ndi zingwe zamagetsi, ndikufupikitsa moyo wake wogwira ntchito.
Kumvetsetsa momwe kutentha kumakhudzira
Pali mitundu iwiri ya kutentha yomwe imakhudza chogwirira ndi kutentha kwa chingwe pamfuti ya MIG komanso kuchuluka kwa nthawi yomwe mungathe kuwotcherera nayo: kutentha kowala kuchokera ku arc ndi kutentha kwachitsulo kuchokera ku chingwe.Kutentha kwamitundu yonseyi kumapangitsanso kuti mfuti ya MIG isankhe.
Kutentha Kwambiri
Kutentha kowala ndi kutentha komwe kumabwerera ku chogwirira kuchokera ku zitsulo zowotcherera ndi zitsulo zoyambira.Ndiwo omwe amachititsa kutentha kwakukulu komwe kumachitika ndi mfuti ya MIG.Zinthu zingapo zimakhudza, kuphatikizapo zinthu zomwe zimawotchedwa.Ngati mumawotcherera aluminiyamu kapena chitsulo chosapanga dzimbiri, mwachitsanzo, mudzapeza kuti chimawonetsa kutentha kwambiri kuposa chitsulo chochepa.
Kusakaniza kwa gasi wotchinga komwe mumagwiritsa ntchito, komanso njira yosinthira kuwotcherera, kungakhudzenso kutentha kowala.Mwachitsanzo, argon imapanga arc yotentha kwambiri kuposa CO2 yoyera, kuchititsa mfuti ya MIG pogwiritsa ntchito argon shielding gasi osakaniza kuti afikire kutentha kwake komwe kumatsika pang'onopang'ono kusiyana ndi kuwotcherera ndi CO2 yoyera.Ngati mugwiritsa ntchito njira yosinthira kupopera, mutha kupezanso kuti ntchito yanu yowotcherera imatulutsa kutentha kwambiri.Izi zimafuna 85 peresenti kapena yolemera ya argon shielding gasi osakaniza, pamodzi ndi chingwe chachitali cha waya ndi kutalika kwa arc, zomwe zimawonjezera voteji mu ntchito ndi kutentha kwathunthu.Chotsatira chake ndi, kachiwiri, kutentha kowala kwambiri.
Kugwiritsa ntchito khosi lalitali la MIG mfuti kungathandize kuchepetsa kutentha kwamphamvu pa chogwiriracho pochiyika motalikirapo kuchokera ku arc ndikuchisunga chozizira.Zomwe mumagwiritsa ntchito zimatha kukhudza kuchuluka kwa kutentha komwe khosi limatenga.Samalani kuti mupeze zogwiritsira ntchito zomwe zimagwirizanitsa mwamphamvu ndikukhala ndi kulemera kwabwino, chifukwa izi zimayamwa kutentha bwino ndipo zingathandize kuteteza khosi kuti lisatenge kutentha kochuluka ku chogwirira.
Kutentha Kwambiri
Kuphatikiza pa kutentha konyezimira, mutha kukumana ndi kutentha kosagwirizana ndi ntchito yanu yowotcherera.Kutentha kosasunthika kumachitika chifukwa cha kukana kwamagetsi mkati mwa chingwe chowotcherera ndipo kumayambitsa kutentha kwakukulu mu chingwecho.Zimachitika pamene magetsi opangidwa ndi gwero la mphamvu sangathe kuyenda kudzera mu chingwe ndi chingwe.Mphamvu yamagetsi "yothandizira" imatayika ngati kutentha.Kukhala ndi chingwe chokwanira kukula kungachepetse kutentha kwamphamvu;komabe, sichingathetseretu.Chingwe chachikulu chomwe chimatha kuthetseratu kukana chingakhale cholemera kwambiri komanso chosasunthika kuti chiyendetsedwe.
Pamene mfuti ya MIG yoziziritsidwa ndi mpweya ikukwera mu amperage, kukula kwa chingwe, kugwirizana ndi zogwirira kumawonjezekanso.Chifukwa chake, mfuti ya MIG yokhala ndi mphamvu zambiri pafupifupi nthawi zonse imakhala ndi misa yambiri.Ngati ndinu wowotcherera mwa apo ndi apo, kulemera kwake ndi kukula kwake sikungakuvutitseni;Komabe, ngati mumawotchera tsiku lonse, tsiku lililonse, ndi bwino kupeza mfuti ya MIG yopepuka komanso yaying'ono yogwirizana ndi pulogalamu yanu.Nthawi zina, izi zingatanthauze kusinthana ndi mfuti ya MIG yoziziritsidwa ndi madzi, yomwe ndi yaying'ono komanso yopepuka, koma imatha kuperekanso mphamvu yowotcherera yomweyi.
Kusankha pakati pa mpweya ndi madzi utakhazikika
Kugwiritsa ntchito mfuti ya MIG yopepuka nthawi zambiri kumatha kukulitsa zokolola chifukwa ndikosavuta kuyendetsa kwa nthawi yayitali.Mfuti zing'onozing'ono za MIG zimathanso kuchepetsa chiwopsezo chanu cha kuvulala kobwerezabwereza, monga matenda a carpal tunnel.
Malingaliro omaliza kuti mukhale omasuka
Posankha mfuti ya MIG, kumbukirani kuti sizinthu zonse zomwe zimapangidwa mofanana.Mfuti ziwiri za MIG zovotera ma 300 amps zimatha kusiyanasiyana malinga ndi kukula kwake komanso kulemera kwake.Pezani nthawi yofufuza zomwe mungasankhe.Komanso, yang'anani zinthu monga chogwirira cholowera mpweya chomwe chimalola kuti mpweya uzidutsamo ndikupangitsa kuti zizizizira.Zinthu zoterezi nthawi zambiri zimatha kulola kuti mfuti iwonetsedwe pamlingo wapamwamba popanda kuwonjezera kukula kapena kulemera kwake.Pomaliza, yang'anani nthawi yomwe mumagwiritsa ntchito kuwotcherera, njira ndi chitetezo chomwe mumagwiritsa ntchito, komanso zida zomwe mukuwotcherera.Kuchita zimenezi kungakuthandizeni kusankha mfuti yomwe imagwirizanitsa bwino pakati pa chitonthozo ndi mphamvu.
