Thaum nws los txog rau vuam, ntau qhov zoo tuaj yeem feem ntau ntxiv rau cov nqi tsis tsim nyog, muaj peev xwm poob qis thiab poob cov khoom lag luam - tshwj xeeb tshaj yog tias koj muaj phom loj MIG rau koj daim ntawv thov.Hmoov tsis zoo, ntau tus neeg ntseeg ib qho kev xav tsis zoo: tias koj xav tau ib rab phom MIG rau qhov siab tshaj plaws amperage koj xav kom vuam (xws li, rab phom 400-amp rau daim ntawv thov 400-amp).Qhov ntawd tsuas yog tsis muaj tseeb.Qhov tseeb, rab phom MIG uas muab lub peev xwm muaj peev xwm ntau dua li qhov koj xav tau feem ntau hnyav dua thiab yuav tsis hloov pauv, ua rau nws tsis yooj yim rau kev ua haujlwm ntawm cov pob qij txha.Ntau dua amperage MIG phom kuj raug nqi ntau dua.
Xaiv rab phom "ntau dhau" tuaj yeem ua rau qaug zog thiab txo koj cov khoom tsim tau.Qhov zoo tshaj plaws MIG rab phom ntaus qhov sib npaug ntawm daim ntawv thov kev thov, thiab MIG phom qhov loj thiab qhov hnyav.
Qhov tseeb yog, vim tias koj siv sijhawm txav mus los, tacking lawv thiab ua lwm yam haujlwm ua ntej thiab tom qab vuam, koj tsis tshua txuas txuas ntxiv kom ncav cuag lub luag haujlwm siab tshaj plaws rau rab phom MIG.Hloov chaw, feem ntau nws yog qhov zoo dua los xaiv lub lightest, yooj yim tshaj plaws phom uas ua tau raws li koj xav tau.Piv txwv li, rab phom MIG ntsuas ntawm 300 amps feem ntau tuaj yeem txuas ntawm 400 amps thiab siab dua - rau qee lub sijhawm - thiab ua haujlwm zoo ib yam.
Cov phom phom piav qhia
Hauv Tebchaws Meskas, National Electrical Manufacturers Association, lossis NEMA, tsim cov MIG phom ntsuas cov qauv.Hauv Tebchaws Europe, cov qauv zoo sib xws yog lub luag haujlwm ntawm Conformité Européenne lossis European Conformity, kuj hu ua CE.
Nyob rau hauv ob lub koom haum, MIG phom tau txais kev ntsuam xyuas uas qhia txog qhov kub thiab txias saum toj no uas tus kov lossis cable ua rau tsis xis nyob.Cov kev ntsuas no, txawm li cas los xij, tsis txheeb xyuas lub ntsiab lus uas MIG phom txaus ntshai lossis tsis ua haujlwm.
Ntau qhov sib txawv yog nyob rau hauv lub luag haujlwm voj voog ntawm rab phom.Cov neeg tsim khoom muaj kev xaiv los ntsuas lawv cov phom ntawm 100-, 60- lossis 35-feem pua lub luag haujlwm.Vim li ntawd, tuaj yeem muaj qhov sib txawv tseem ceeb thaum sib piv cov khoom siv phom MIG sib txawv.
Lub voj voog lub luag haujlwm yog tus nqi ntawm lub sijhawm arc-nyob rau hauv lub sijhawm 10-feeb.Ib lub tuam txhab phom MIG tuaj yeem tsim tau 400-amp MIG phom uas muaj peev xwm vuam ntawm 100 feem pua lub luag haujlwm lub voj voog, thaum lwm tus tsim cov phom MIG tib yam uas tuaj yeem vuam ntawm tsuas yog 60 feem pua lub voj voog.Hauv qhov ua piv txwv no, thawj rab phom MIG yuav tuaj yeem txuas tau zoo tsis tu ncua ntawm tag nrho amperage rau 10-feeb lub sijhawm, qhov tom kawg tsuas tuaj yeem txuas tau 6 feeb xwb.
Ua ntej txiav txim siab uas MIG phom yuav yuav, nws yog ib qho tseem ceeb uas yuav tsum tau tshuaj xyuas lub luag hauj lwm voj voog piv rau cov khoom.Feem ntau koj tuaj yeem pom cov ntaub ntawv no hauv cov ntaub ntawv khoom lossis ntawm cov chaw tsim khoom lub vev xaib.
Koj ua haujlwm li cas?
Raws li cov lus piav qhia ntawm rab phom saum toj no, nws tseem yog qhov tseem ceeb rau koj los txiav txim siab lub sijhawm koj siv vuam ua ntej koj xaiv MIG phom.Saib seb koj siv sij hawm siv vuam ntau npaum li cas hauv 10 feeb.Tej zaum koj yuav xav tsis thoob tias qhov nruab nrab arc-on lub sij hawm feem ntau yog tsawg dua 5 feeb.
Nco ntsoov tias vuam nrog rab phom MIG ntsuas rau 300 amps yuav tshaj nws cov peev xwm ntsuas yog tias koj yuav tsum siv nws ntawm 400 amps thiab 100 feem pua lub luag haujlwm voj voog.Txawm li cas los xij, yog tias koj siv tib rab phom los txuas ntawm 400 amps thiab 50 feem pua lub luag haujlwm, nws yuav tsum ua haujlwm zoo.Ib yam li ntawd, yog tias koj muaj daim ntawv thov uas yuav tsum tau vuam cov hlau tuab heev ntawm cov khoom siv tam sim no (txawm tias 500 amps lossis ntau dua) rau lub sijhawm luv luv, koj tuaj yeem siv rab phom ntsuas ntawm 300 amps xwb.
Raws li txoj cai dav dav, rab phom MIG ua rau tsis xis nyob thaum nws tshaj nws cov dej num tag nrho ntawm qhov ntsuas kub.Yog tias koj pom koj tus kheej welding ntev dua li niaj zaus, koj yuav tsum xav txog qhov vuam ntawm lub voj voog qis lossis hloov mus rau rab phom siab dua.Tshaj ib rab phom MIG qhov ntsuas kub muaj peev xwm ua rau muaj kev sib txuas tsis muaj zog thiab lub zog hluav taws xob, thiab ua rau nws lub neej ua haujlwm luv.
To taub qhov cuam tshuam ntawm tshav kub
Muaj ob hom cua sov uas cuam tshuam rau tus kov thiab cable kub ntawm rab phom MIG thiab lub sijhawm koj tuaj yeem txuas nrog nws: radiant tshav kub los ntawm arc thiab resistive tshav kub los ntawm lub cable.Ob qho ntawm cov cua sov no kuj tseem ceeb rau qhov ntsuas ntawm MIG phom koj yuav tsum xaiv.
Radiant Kub
Radiant tshav kub yog cua sov uas qhia rov qab mus rau tus kov los ntawm vuam arc thiab lub hauv paus hlau.Nws yog lub luag haujlwm rau feem ntau ntawm cov cua sov uas tau ntsib los ntawm MIG rab phom kov.Ntau yam cuam tshuam rau nws, nrog rau cov khoom siv welded.Yog tias koj vuam aluminium lossis stainless hlau, piv txwv li, koj yuav pom tias nws muaj kev cuam tshuam ntau dua li cov hlau me me.
Kev sib xyaw roj shielding koj siv, nrog rau cov txheej txheem vuam hloov pauv, tuaj yeem cuam tshuam rau cov cua sov.Piv txwv li, argon tsim ib tug kub arc tshaj li ntshiab CO2, ua rau ib tug MIG phom siv ib tug argon shielding roj sib tov kom ncav cuag nws rated kub ntawm ib tug qis amperage tshaj thaum vuam nrog ntshiab CO2.Yog tias koj siv cov txheej txheem hloov pauv, koj tuaj yeem pom tias koj daim ntawv thov vuam ua kom muaj cua sov ntau dua.Cov txheej txheem no yuav tsum muaj 85 feem pua lossis nplua nuj argon shielding roj sib tov, nrog rau cov hlau nplaum ntev dua thiab arc ntev, ob qho tib si ntawm qhov ua kom muaj zog hauv daim ntawv thov thiab tag nrho qhov kub thiab txias.Qhov tshwm sim yog, dua, ntau radiant tshav kub.
Siv lub caj dab ntev MIG phom tuaj yeem pab txo qis qhov cuam tshuam ntawm radiant tshav kub ntawm tus kov los ntawm kev tso nws ntxiv los ntawm arc thiab ua kom nws txias dua.Cov khoom siv uas koj siv tau tuaj yeem cuam tshuam cov cua sov uas lub caj dab absorbs.Saib xyuas kom pom cov khoom siv uas sib txuas kom nruj thiab muaj cov khoom zoo, vim tias cov khoom no nqus tau cov cua sov zoo dua thiab tuaj yeem pab tiv thaiv lub caj dab kom tsis txhob nqa cov cua sov mus rau qhov kov.
Resistive Thaum tshav kub kub
Ntxiv nrog rau cov cua sov radiant, koj tuaj yeem ntsib cov cua sov hauv koj daim ntawv thov vuam.Resistive tshav kub tshwm sim los ntawm txoj kev ntawm hluav taws xob tsis kam nyob rau hauv lub vuam cable thiab yog lub luag hauj lwm rau feem ntau ntawm cov cua sov nyob rau hauv lub cable.Nws tshwm sim thaum cov hluav taws xob tsim los ntawm lub zog hluav taws xob tsis tuaj yeem ntws los ntawm kev sib txuas ntawm cable thiab cable.Lub zog ntawm "them rov qab" hluav taws xob poob li cua sov.Muaj qhov loj me me ntawm cable tuaj yeem txo qhov cua sov;txawm li cas los xij, nws tsis tuaj yeem tshem tawm tag nrho.Ib lub cable loj txaus kom tshem tawm qhov kev tawm tsam yuav hnyav dhau thiab tsis muaj zog rau kev ua haujlwm.
Raws li cov phom cua txias MIG nce hauv amperage, qhov loj ntawm cable, kev sib txuas thiab cov tes tuav kuj nce.Yog li ntawd, rab phom MIG nrog lub peev xwm siab dua yuav luag ib txwm muaj ntau dua.Yog tias koj yog ib tug welder qee zaus, qhov hnyav thiab qhov loj tuaj yuav tsis thab koj;Txawm li cas los xij, yog tias koj txuas txhua hnub, txhua hnub, nws yog qhov zoo dua los nrhiav ib rab phom MIG sib dua thiab me dua rau koj daim ntawv thov.Qee zaum, qhov ntawd yuav txhais tau tias hloov mus rau ib rab phom MIG dej txias, uas yog me dua thiab sib dua, tab sis kuj tuaj yeem muab tib lub peev xwm vuam.
Kev txiav txim siab ntawm huab cua- thiab dej-txias
Siv rab phom MIG sib zog tuaj yeem txhim kho cov khoom tsim tau ntau dua vim nws yooj yim dua rau kev ua haujlwm ntev dua.Cov phom me me kuj tseem tuaj yeem txo koj qhov cuam tshuam rau kev raug mob rov ua dua, xws li carpal tunnel syndrome.
Qhov kawg xav kom koj xis nyob
Thaum xaiv koj rab phom MIG, nco ntsoov tias tsis yog txhua yam khoom tsim muaj sib npaug.Ob rab phom MIG ntsuas rau 300 amps tuaj yeem sib txawv ntawm lawv qhov loj thiab qhov hnyav.Siv sijhawm los tshawb nrhiav koj cov kev xaiv.Tsis tas li ntawd, nrhiav cov yam ntxwv zoo li lub tshuab ua pa uas tso cai rau huab cua ntws los ntawm nws thiab ua kom nws txias dua.Cov yam ntxwv zoo li no feem ntau tuaj yeem tso cai rau rab phom kom muaj peev xwm ntau dua yam tsis ntxiv qhov loj lossis qhov hnyav.Thaum kawg, ntsuas lub sij hawm koj siv vuam, txheej txheem thiab thaiv cov roj uas koj siv, thiab cov ntaub ntawv uas koj welding.Ua li no tuaj yeem pab koj xaiv rab phom uas ua rau qhov zoo tshaj plaws sib npaug ntawm kev nplij siab thiab lub peev xwm.
