Kev noj cov hlau tsis zoo yog ib qho teeb meem tshwm sim hauv ntau qhov kev ua haujlwm vuam. Hmoov tsis zoo, nws tuaj yeem yog qhov tseem ceeb ntawm kev poob qis thiab poob kev tsim khoom - tsis hais txog tus nqi.
Kev noj zaub mov tsis zoo lossis tsis zoo tuaj yeem ua rau tsis ua haujlwm ntxov ntawm cov khoom siv, burnbacks, noog-zes thiab ntau dua. Yuav kom daws tau qhov teeb meem yooj yim, nws yog qhov zoo tshaj plaws los nrhiav cov teeb meem hauv cov hlau feeder ua ntej thiab txav mus rau pem hauv ntej ntawm rab phom mus rau cov khoom siv.
Nrhiav qhov laj thawj ntawm qhov teeb meem tuaj yeem qee zaum nyuaj, txawm li cas los xij, cov teeb meem kev noj zaub mov feem ntau muaj cov kev daws teeb meem yooj yim.
Dab tsi tshwm sim nrog lub feeder?
Nrhiav qhov ua rau tsis zoo ntawm cov hlau tsis zoo tuaj yeem qee zaum nyuaj, txawm li cas los xij, qhov teeb meem feem ntau muaj cov kev daws teeb meem yooj yim.
Thaum tsis zoo xaim pub mis tshwm sim, nws tuaj yeem cuam tshuam nrog ntau yam hauv cov hlau feeder.
1. Yog hais tias tus tsav rolls tsis txav thaum koj rub lub trigger, xyuas seb lub relay puas lawm. Hu rau koj lub chaw tsim khoom feeder rau kev pab yog tias koj xav tias qhov no yog qhov teeb meem. Kev tswj cov hlau lead ua tsis raug yog lwm qhov ua tau. Koj tuaj yeem kuaj xyuas cov hlau lead nrog lub multimeter los txiav txim seb puas xav tau ib lub cable tshiab.
2. Ib qho kev teeb tsa tsis raug thiab/lossis txoj kab uas hla txoj kab uas hla tsis raug yuav yog tus txhaum. Txoj kev qhia lub raj zaum nruab nrab ntawm lub hwj chim tus pin thiab tus tsav rolls kom cov hlau noj zoo ntawm tus tsav yob mus rau hauv rab phom. Ib txwm siv lub raj qhia me me kom zoo, kho cov kev taw qhia kom ze rau ntawm qhov tsav rolls li sai tau thiab tshem tawm txhua qhov khoob hauv txoj kab hlau.
3. Nrhiav kev sib txuas tsis zoo yog tias koj rab phom MIG muaj lub adapter uas txuas rab phom mus rau lub feeder. Xyuas lub adapter nrog ib tug multimeter thiab hloov nws yog hais tias nws yog malfunctioning.
Ua tib zoo saib cov rolls
Noog-zes, qhia ntawm no, tuaj yeem ua rau thaum lub liner raug txiav luv luv lossis lub liner yog qhov loj me me rau cov xaim siv.
Kev siv qhov loj me lossis cov qauv ntawm vuam tsav yob tuaj yeem ua rau cov hlau tsis zoo. Nov yog qee cov lus qhia kom tsis txhob muaj teeb meem.
1. Nco ntsoov phim tus tsav yob loj rau cov hlau txoj kab uas hla.
2. Tshawb xyuas cov yob txhua lub sij hawm koj muab ib tug tshiab spool ntawm hlau rau ntawm cov hlau feeder. Hloov raws li qhov tsim nyog.
3. Xaiv cov style ntawm tsav yob raws li cov hlau koj siv. Piv txwv li, cov welding du yob yog qhov zoo rau kev vuam nrog cov khoom siv hlau, qhov U-puab zoo dua rau cov xaim tubular - flux-cored lossis hlau-cored.
4. Teem lub tsav kom zoo yob nro kom muaj lub siab txaus ntawm cov vuam hlau kom pub nws zoo.
Kos lub liner
Ob peb qhov teeb meem nrog lub vuam liner tuaj yeem ua rau cov xaim tsis zoo, nrog rau kev kub hnyiab thiab noog-zes.
1. Nco ntsoov tias lub liner raug txiav kom raug qhov ntev. Thaum koj nruab thiab txiav lub liner, nteg rab phom tiaj tus, ua kom cov kab ncaj nraim. Kev siv lub ntsuas ntsuas liner yog pab tau. Kuj tseem muaj cov khoom siv hluav taws xob muaj nrog cov kab uas tsis tas yuav ntsuas. Lawv kaw thiab concentrically sib dhos ntawm cov lus qhia thiab lub hwj chim tus pin yam tsis muaj fasteners. Cov tshuab no muab cov ntaub ntawv pov thawj yuam kev hloov pauv kom tshem tawm cov teeb meem pub mis.
2. Kev siv cov hlua vuam tsis zoo rau cov vuam hlau feem ntau ua rau muaj teeb meem kev noj cov hlau. Xaiv ib lub liner uas loj me ntsis ntawm txoj kab uas hla ntawm cov xaim, raws li nws tso cai rau cov xaim pub kom zoo. Yog hais tias lub liner nqaim heev, nws yuav nyuaj rau noj, ua rau cov hlau tawg lossis noog-zes.
3. Cov khib nyiab buildup hauv liner tuaj yeem cuam tshuam cov xaim pub. Nws tuaj yeem tshwm sim los ntawm kev siv qhov tsis raug vuam tsav yob hom, ua rau cov hlau shavings hauv liner. Microarcing tseem tuaj yeem tsim cov weld me me hauv cov liner. Hloov cov welding liner thaum buildup tshwm sim nyob rau hauv erratic hlau noj. Koj tseem tuaj yeem tshuab cua compressed los ntawm lub cable kom tshem tawm cov av thiab cov khib nyiab thaum koj hloov lub liner.
Kaw ntawm ib tug hlau burnback nyob rau hauv ib tug tiv tauj lub ntsiab lus ntawm ib tug self-shielded FCAW phom. Tshawb xyuas cov lus qhia tiv tauj tsis tu ncua rau hnav, av thiab khib nyiab los pab tiv thaiv kev kub hnyiab (pom ntawm no) thiab hloov cov lus qhia tiv tauj raws li qhov tsim nyog.
Saib xyuas kev tiv thaiv kev hnav
Welding consumables yog ib feem me me ntawm rab phom MIG, tab sis lawv tuaj yeem cuam tshuam rau kev pub hlau - tshwj xeeb tshaj yog cov lus qhia. Kom tsis txhob muaj teeb meem:
1. Saib xyuas qhov kev tiv tauj rau kev hnav tsis tu ncua thiab hloov raws li qhov tsim nyog. Saib rau cov cim qhia ntawm keyholing, uas tshwm sim thaum lub bore nyob rau hauv qhov kev sib cuag lub taub hau ua oblong nyob rau lub sij hawm vim yog cov hlau noj los ntawm nws. Kuj saib rau spatter buildup, vim qhov no yuav ua rau burnbacks thiab tsis zoo hlau noj.
2. Xav txog kev nce lossis txo qhov loj ntawm cov lus qhia koj siv. Sim nqis mus rau ib qho me me ua ntej, uas tuaj yeem pab txhawb kev tswj hwm ntawm arc thiab kev noj zaub mov zoo dua.
Kev xav ntxiv
Kev noj cov hlau tsis zoo tuaj yeem ua rau muaj kev ntxhov siab hauv koj txoj haujlwm vuam - tab sis nws tsis tas yuav ua rau koj qeeb ntev. Yog tias koj tseem muaj teeb meem tom qab kuaj xyuas thiab hloov kho los ntawm lub feeder rau pem hauv ntej, saib koj rab phom MIG. Nws yog qhov zoo tshaj plaws los siv cov kab hluav taws xob luv tshaj plaws uas tseem tuaj yeem ua tiav txoj haujlwm. Cov kab hluav taws xob luv luv txo cov coiling uas tuaj yeem ua rau muaj teeb meem pub mis. Nco ntsoov khaws cov cable kom ncaj li sai tau thaum lub sij hawm vuam, thiab. Ua ke nrog qee qhov kev txawj daws teeb meem, rab phom zoo tuaj yeem ua rau koj vuam ntev dua.
