4 hom soldering hlau faults thiab kho txoj kev
1. Lub tshuab hluav taws xob hluav taws xob tsis tsim hluav taws xob tom qab siv hluav taws xob.
Yog hais tias cov hlau soldering tsis kub tom qab tau muab tso rau, nws txhais tau hais tias cov hlau soldering muaj ib tug qhib Circuit Court txhaum. Qhov kev ua txhaum no tuaj yeem tshwm sim ntawm qhov ntsaws ntawm cov hlau soldering hauv ntau qhov chaw. Cov tub ntxhais hlau soldering tau tawg, cov hlau lead ntawm cov tub ntxhais hlau soldering yog txiav, thiab lub hwj chim qaum ntawm cov hlau soldering yog txiav.
2. Lub taub hau hlau tsis noj tin.
Lub taub hau soldering tsis noj. "Xi Pu tau pom tias cov hlau nplaum uas tau muag tshiab tau siv ncaj qha yam tsis tau kho, ua rau cov hlau taub hau tsis raug tinned. Lub taub hau hlau siv tau ntev tsis tau tinned, thiab cov hlau taub hau tau hlawv thiab xav tau. yuav tsum kho.
3. Cov hlau nplaum raug them
Ib tug nqi soldering hlau yog txaus ntshai heev rau welders thiab tej zaum yuav ua rau muaj teeb meem hluav taws xob loj. Yog li ntawd, thaum pom cov hlau soldering raug them, lub hwj huam mov yuav tsum raug txiav tam sim ntawd rau kev tshuaj xyuas. Muaj ob peb lub laj thawj vim li cas cov hlau soldering ua hluav taws xob: lub hwj chim qaum ntawm cov hlau soldering txuas nrog lub davhlau ya nyob twg ntawm cov hlau hauv av; lub hwj chim qaum ntog tawm ntawm lub davhlau ya nyob twg ntawm cov tub ntxhais hlau soldering thiab ces kov cov ntsia hlau ntawm cov hlau hauv av, ua rau cov hluav taws xob hluav taws xob ntawm lub taub hau ntawm cov hlau soldering ua rau entangled thiab ua rau to; Lub zog hauv av hlau nws tus kheej xau hluav taws xob.
4. Lub qhov dej tshwm rau ntawm lub taub hau hlau
Thaum siv cov hlau nplaum rau lub sijhawm, cov pits lossis txheej txheej oxidized corrosion yuav tshwm sim ntawm cov hlau nplaum, ua rau cov duab ntawm cov hniav ntawm cov hlau taub hau hloov. Thaum ntsib qhov teeb meem no, koj tuaj yeem siv cov ntaub ntawv tshem tawm cov oxide txheej thiab cov pits, xa lawv mus rau hauv lawv cov qauv qub, thiab tom qab ntawd muab lawv nrog cov tin, thiab koj tuaj yeem rov siv dua.
Kho txoj kev rau soldering hlau uas tsis kub li tom qab tau powered on
(1) Thaum lub tshuab hluav taws xob hluav taws xob tau siv rau thiab pom tias lub hau ntawm cov hlau soldering tsis kub, feem ntau yog vim lub hwj chim qaum tau poob los yog cov tub ntxhais hlau ntawm cov hlau soldering puas lawm. Hauv qhov xwm txheej zoo li no, koj tuaj yeem siv R × lkn thaiv ntawm multimeter los ntsuas ob qhov kawg ntawm lub hwj chim ntsaws. Yog hais tias lub multimeter pointer Yog hais tias nws tsis txav, nws txhais tau hais tias muaj ib tug qhib Circuit Court txhaum.
(2) Ua ntej xyuas seb cov hlau lead ntawm lub ntsaws nws tus kheej qhib. Yog tias tsis yog, tshem tawm tus kov Bakelite, thiab tom qab ntawd siv lub tshuab multimeter los ntsuas ob txoj hauv kev ntawm cov tub ntxhais hlau soldering. Yog hais tias lub multimeter pointer tseem tsis txav, nws txhais tau hais tias cov tub ntxhais hlau soldering puas lawm thiab cov hlau soldering yuav tsum tau hloov. Lub plawv.
(3) Qhov kev tiv thaiv ntawm ob qho tib si ntawm 35W sab hauv cov cua sov soldering hlau tub ntxhais yog 1. Nyob ib ncig ntawm Skfl, yog tias qhov ntsuas qhov ntsuas tsis zoo yog qhov qub, nws txhais tau tias cov tub ntxhais hlau soldering yog qhov zoo. Qhov txhaum tshwm sim hauv lub hwj chim coj thiab lub ntsaws nws tus kheej. Feem ntau faults yog qhib circuits nyob rau hauv lub leads. Yog tias cov tub ntxhais hlau yuav tsum tau hloov pauv, ntxig ib qho tshiab soldering hlau tub ntxhais ntawm tib yam tshwj xeeb rau hauv cov pas nrig txuas, txhim kho cov hlau lead ntawm cov ntsia hlau kho, thiab nruj lub davhlau ya nyob twg. Nyob rau tib lub sijhawm, nco ntsoov txiav tawm qhov dhau ntawm cov hlau lead ntawm cov tub ntxhais hlau los tiv thaiv ob txoj hauv kev luv luv.
