Uma kuziwa ekushiseleni, into enhle kakhulu ngokuvamile ingangeza ezindlekweni ezingadingekile, isikhathi sokuphumula esingaba khona kanye nokulahlekelwa umkhiqizo - ikakhulukazi uma unesibhamu esikhulu kakhulu se-MIG sohlelo lwakho lokusebenza. Ngeshwa, abantu abaningi bakholelwa umbono oyiphutha ovamile: ukuthi udinga isibhamu se-MIG esilinganiselwe ezingeni eliphezulu kakhulu olindele ukushisela (isb., isibhamu esingu-400-amp sohlelo lokusebenza lwe-400-amp). Lokho akulona iqiniso. Eqinisweni, isibhamu se-MIG esihlinzeka ngomthamo ophezulu we-amperage kunalokho okudingayo ngokuvamile sinesisindo esikhulu futhi singase singaguquguquki kancane, sikwenze kungabi ntofontofo ukuhambahamba eduze kwamajoyinti okushisela. Izibhamu ezisezingeni eliphezulu ze-MIG nazo zibiza ngaphezulu.
Ukukhetha isibhamu "esiningi kakhulu" kungakhuphula ukukhathala futhi kunciphise ukukhiqiza kwakho. Isibhamu esikahle se-MIG sishaya ibhalansi phakathi kwezimfuno zohlelo lokusebenza, nosayizi nesisindo sesibhamu se-MIG.
Iqiniso liwukuthi, ngenxa yokuthi uchitha isikhathi uhambisa izingxenye, uzibambe futhi wenza eminye imisebenzi yangaphambi nangemuva kokushisela, awuvamisile ukushisela ngokuqhubekayo ukuze ufinyelele umkhawulo womsebenzi waleso sibhamu se-MIG. Kunalokho, kuvame ukuba ngcono ukukhetha isibhamu esilula, esivumelana nezimo kakhulu esihlangabezana nezidingo zakho. Isibonelo, isibhamu se-MIG esilinganiselwe kuma-amps angu-300 ngokuvamile singashisela kuma-amps angu-400 nangaphezulu - isikhathi esilinganiselwe - futhi senze umsebenzi omuhle nje.
Kuchazwe izilinganiso zezibhamu
E-United States, i-National Electrical Manufacturers Association, noma i-NEMA, isungula imibandela yokulinganisa isibhamu se-MIG. E-Europe, izindinganiso ezifanayo ziwumthwalo we-Conformité Européenne noma i-European Conformity, ebizwa nangokuthi i-CE.
Ngaphansi kwazo zombili izinhlaka, izibhamu ze-MIG zithola isilinganiso esibonisa izinga lokushisa elingaphezulu lapho isibambo noma ikhebula lifudumala ngokungafanele. Lezi zilinganiso, nokho, azikhombi iphuzu lapho isibhamu se-MIG sibeka engcupheni yokulimala noma ukwehluleka.
Umehluko omningi usemjikelezweni womsebenzi wesibhamu. Abakhiqizi banenketho yokulinganisa izibhamu zabo emijikelezweni yomsebenzi wamaphesenti ayi-100, angama-60- noma angama-35. Ngaleso sizathu, kungase kube nomehluko omkhulu lapho kuqhathaniswa imikhiqizo ehlukene yomkhiqizi wezibhamu we-MIG.
Umjikelezo womsebenzi inani lesikhathi esibekiwe phakathi nenkathi eyimizuzu eyi-10. Umkhiqizi wezibhamu we-MIG oyedwa angase akhiqize isibhamu se-MIG esingu-400-amp esikwazi ukushisela ngamaphesenti angu-100 omjikelezo womsebenzi, kuyilapho omunye akhiqiza isibhamu esinamandla se-MIG esingashisela ngomjikelezo womsebenzi ongamaphesenti angu-60 kuphela. Kulesi sibonelo, isibhamu sokuqala se-MIG sizokwazi ukushisela ngaso sonke isikhathi silingana nesilinganiso sesikhathi esiyimizuzu eyi-10, kanti lesi sakamuva sizokwazi ukushisela imizuzu engu-6 kuphela.
Ngaphambi kokunquma ukuthi yisiphi isibhamu se-MIG esizosithenga, kubalulekile ukuthi ubuyekeze izilinganiso zomjikelezo wemisebenzi yomkhiqizo. Ngokuvamile ungathola lolu lwazi ezincwadini zomkhiqizo noma kuwebhusayithi yomkhiqizi.
Usebenza kanjani?
Ngokusekelwe encazelweni yesilinganiso sesibhamu esingenhla, kubalulekile futhi kuwe ukuthi ucabangele ubude besikhathi osichitha ushisela ngaphambi kokukhetha isibhamu sakho se-MIG. Bheka ukuthi singakanani isikhathi osichitha ushisela phakathi nemizuzu eyi-10. Ungase umangale ukuthola ukuthi isikhathi esimaphakathi se-arc ngokuvamile singaphansi kwamaminithi angu-5.
Khumbula ukuthi ukushisela ngesibhamu se-MIG esilinganiselwe kuma-amps angu-300 kuzodlula umthamo waso olinganiselwe uma ubungawusebenzisa kuma-amps angu-400 kanye nomjikelezo womsebenzi wamaphesenti angu-100. Kodwa-ke, uma usebenzise leso sibhamu ukushisela kuma-amps angu-400 kanye nomjikelezo womsebenzi wamaphesenti angu-50, kufanele sisebenze kahle. Ngokufanayo, uma ubunohlelo oludinga ukushisela insimbi ewugqinsi kakhulu emithwalweni ephezulu yamanje (ngisho nama-amps angu-500 noma ngaphezulu) isikhathi esifushane kakhulu, ungase ukwazi ukusebenzisa isibhamu esilinganiselwe ngama-amps angu-300 kuphela.
Njengomthetho ojwayelekile, isibhamu se-MIG sishisa ngendlela engathandeki uma seqa izinga lokushisa lomjikelezo waso ophelele womsebenzi. Uma uzithola usushisela isikhathi eside njalo, kufanele ucabangele ukushisela emjikelezweni womsebenzi ophansi noma ushintshele kwisibhamu esilinganiselwe phezulu. Ukweqa izinga lokushisa elilinganiselwe lesibhamu se-MIG kungaholela ekuxhumekeni okubuthakathaka namakhebuli kagesi, futhi kufinyeze impilo yayo yokusebenza.
Ukuqonda umthelela wokushisa
Kunezinhlobo ezimbili zokushisa ezithinta isibambo nezinga lokushisa lekhebula kusibhamu se-MIG kanye nesikhathi ongakwazi ukushisela ngaso: ukushisa okukhazimulayo okuvela ku-arc nokushisa okuphikisayo okuvela kukhebuli. Zombili lezi zinhlobo zokushisa ziphinde zifake isandla ekutheni isiphi isilinganiso sesibhamu se-MIG okufanele usikhethe.
Ukushisa Okukhazimulayo
Ukushisa okukhazimulayo ukushisa okubuyisela emuva kusibambo kusukela ku-arc yokushisela kanye nesisekelo sensimbi. Ibophezelekile ekushiseni okuningi okuhlangabezane nesibambo sesibhamu se-MIG. Kunezici eziningana eziwuthintayo, okuhlanganisa nezinto ezishiselwe. Uma ushisela i-aluminium noma insimbi engagqwali, isibonelo, uzothola ukuthi ikhombisa ukushisa okukhulu kunensimbi ethambile.
Ingxube yegesi evikelayo oyisebenzisayo, kanye nenqubo yokudlulisa i-welding, nayo ingathinta ukushisa okukhazimulayo. Isibonelo, i-argon idala i-arc eshisayo kune-CO2 ehlanzekile, okwenza isibhamu se-MIG sisebenzisa ingxube yegesi evikela i-argon ukuze sifinyelele izinga lokushisa elilinganiselwe nge-amperage ephansi kunalapho sishisela nge-CO2 ehlanzekile. Uma usebenzisa inqubo yokudlulisa isifutho, ungathola futhi ukuthi uhlelo lwakho lokushisela lukhiqiza ukushisa okwengeziwe. Le nqubo idinga amaphesenti angu-85 noma acebile ingxube yegesi evikela i-argon, kanye nenduku ende yocingo nobude be-arc, kokubili okwandisa i-voltage kuhlelo lokusebenza kanye nezinga lokushisa lilonke. Umphumela uba, futhi, ukushisa okukhazimulayo okwengeziwe.
Ukusebenzisa intamo ende yesibhamu se-MIG kungasiza ukunciphisa umthelela wokushisa okukhazimulayo kusibambo ngokusibeka kude ne-arc nokuyigcina ipholile. Izinto ezisetshenziswayo ozisebenzisayo zingase zithinte inani lokushisa elimuncwa intamo. Nakekela ukuthola izinto ezisetshenziswayo ezixhumeka ngokuqinile futhi ezinesisindo esihle, njengoba lezi zimunca ukushisa kangcono futhi zingasiza ukuvimbela intamo ekuthwaleni ukushisa okungaka kusibambi.
Ukushisa Okuqinile
Ngokungeziwe ekushiseni okukhazimulayo, ungase uhlangabezane nokushisa okuphikisayo ohlelweni lwakho lokushisela. Ukushisa okubamba iqhaza kwenzeka ngendlela yokumelana nogesi ngaphakathi kwekhebula lokushisela futhi kunesibopho sokushisa okuningi kukhebula. Kwenzeka lapho ugesi okhiqizwa umthombo wamandla ungakwazi ukugeleza ngentambo nokuxhunywa kwekhebula. Amandla kagesi "asekelwe" alahleka njengokushisa. Ukuba nekhebula elinosayizi okwanele kunganciphisa ukushisa okuphikisayo; nokho, ayikwazi ukukuqeda ngokuphelele. Ikhebuli enkulu ngokwanele ukuqeda ngokuphelele ukumelana izoba nzima kakhulu futhi ingalawuleki ukuyiqondisa.
Njengoba isibhamu se-MIG esipholile emoyeni sikhuphuka nge-amperage, ubukhulu bekhebula, ukuxhumana nezibambo nakho kuyanda. Ngakho-ke, isibhamu se-MIG esinamandla amakhulu alinganiselwe cishe ngaso sonke isikhathi sinesisindo esikhulu. Uma ungumshiseli ngezikhathi ezithile, leso sisindo nokwanda kosayizi kungase kungakukhathazi; kodwa-ke, uma ushisela usuku lonke, nsuku zonke, kungcono ukuthola isibhamu se-MIG esilula nesincane esilungele isicelo sakho. Kwezinye izimo, lokho kungase kusho ukushintshela kusibhamu se-MIG esipholile ngamanzi, esincane futhi esilula, kodwa singanikeza umthamo ofanayo wokushisela.
Ukunquma phakathi kokupholisa umoya namanzi
Ukusebenzisa isibhamu se-MIG esilula ngokuvamile kungathuthukisa ukukhiqiza njengoba kulula ukusilawula isikhathi eside. Izibhamu ezincane ze-MIG nazo zinganciphisa ukuthambekela kwakho ekulimaleni okuphindaphindiwe kokunyakaza, njenge-carpal tunnel syndrome.
Imicabango yokugcina yokukugcina ukhululekile
Lapho ukhetha isibhamu sakho se-MIG, khumbula ukuthi akuyona yonke imikhiqizo edalwe ilingana. Izibhamu ezimbili ze-MIG ezilinganiselwe kuma-amps angu-300 zingahluka kakhulu ngokobukhulu bazo kanye nesisindo sazo. Zinike isikhathi sokucwaninga izinketho zakho. Futhi, bheka izici ezifana nesibambo esingenisa umoya esivumela umoya ukuba ugeleze kuso futhi sigcine sipholile. Izici ezinjalo ngokuvamile zingavumela isibhamu ukuba silinganiselwe kumthamo ophezulu ngaphandle kokwengeza noma yimuphi usayizi noma isisindo. Okokugcina, hlola isikhathi osichitha ushisela, inqubo negesi yokuvikela oyisebenzisayo, nezinto ozishiselayo. Ukwenza kanjalo kungakusiza ukuthi ukhethe isibhamu esifinyelela ukulingana okuhle phakathi kokunethezeka namandla.
