Mid-frequency DC chaw welders yog cov cuab yeej tseem ceeb hauv ntau qhov kev lag luam, muab qhov tseeb thiab kev ua haujlwm zoo hauv kev koom nrog cov khoom siv hlau. Txawm li cas los xij, zoo li txhua lub tshuab ua haujlwm nyuaj, lawv tuaj yeem ntsib teeb meem uas yuav tsum tau kho thiab kho. Hauv tsab xov xwm no, peb yuav tham txog cov teeb meem uas tshwm sim nrog ib nrab zaus DC qhov chaw vuam thiab yuav ua li cas daws lawv kom zoo.
1. Tsis muaj vuam tam sim no tso zis
Thaum koj qhov chaw welder tsis tsim cov vuam tam sim no, pib los ntawm kev kuaj xyuas lub zog. Xyuas kom meej tias lub tshuab txuas nrog lub zog txhim khu kev qha thiab tias lub tshuab hluav taws xob tsis raug cuam tshuam. Yog tias cov khoom siv hluav taws xob tsis zoo, tshawb xyuas cov welding cables kom muaj kev puas tsuaj lossis kev sib txuas xoob. Faulty cables tuaj yeem cuam tshuam cov dej ntws tam sim no, ua rau tsis muaj qhov tso tawm. Hloov lossis kho cov kab hluav taws xob puas raws li xav tau.
2. Tsis sib xws Welds
Cov welds tsis sib xws tuaj yeem yog qhov teeb meem ntxhov siab, feem ntau tshwm sim los ntawm qhov tsis sib xws los yog kev sib raug zoo ntawm cov khoom ua haujlwm. Ua ntej, paub meej tias cov vuam electrodes yog huv si thiab zoo. Tom ntej no, xyuas kom meej tias cov workpieces raug raug raws thiab ruaj khov. Kho qhov vuam siab thiab electrode quab yuam kom ua tiav qhov sib xws. Yog tias qhov teeb meem tshwm sim, nws yuav tsum tau kuaj xyuas thiab, yog tias tsim nyog, hloov cov lus qhia vuam lossis electrodes.
3. Kub kub
Overheating yog ib qho teeb meem tshwm sim nyob rau hauv qhov chaw welders thiab tuaj yeem ua rau txo qis kev ua haujlwm thiab txawm tias muaj kev puas tsuaj rau lub tshuab. Txhawm rau daws qhov teeb meem no, ua ntej, xyuas kom meej tias qhov chaw welder tau txias txaus. Ntxuav cov cua txias, nrog rau cov kiv cua thiab cov ntxaij lim dej, kom ntseeg tau tias cov cua ntws zoo. Tsis tas li ntawd, xyuas seb muaj kev cuam tshuam nyob ib puag ncig lub tshuab uas tuaj yeem cuam tshuam qhov txias.
4. Tswj vaj huam sib luag ua haujlwm tsis zoo
Yog hais tias tus tswj vaj huam sib luag qhia qhov yuam kev los yog malfunctions, xa mus rau tus neeg siv phau ntawv rau kev ua yuam kev code piav qhia thiab teeb meem kev taw qhia. Feem ntau niaj hnub nruab nrab zaus DC qhov chaw vuam muaj cov yam ntxwv kuaj mob uas tuaj yeem pab txheeb xyuas qhov teeb meem. Yog tias muaj teeb meem tshwm sim, hu rau lub chaw tsim khoom cov neeg siv khoom txhawb nqa rau kev pab ntxiv.
5. Ncaim heev
Lub txim taws ntau dhau thaum lub vuam txheej txheem tuaj yeem ua rau muaj kev phom sij thiab yuav qhia tau tias muaj teeb meem nrog cov electrodes lossis workpieces. Txheeb xyuas qhov xwm txheej ntawm cov vuam electrodes thiab xyuas kom meej tias lawv tau ua kom zoo thiab sib cuag nrog cov khoom ua haujlwm. Tshawb xyuas cov chaw ua haujlwm rau cov kab mob xws li xeb, xim, lossis roj, vim tias cov no tuaj yeem ua rau tawg. Ntxuav qhov chaw kom huv si ua ntej sim welding.
Hauv kev xaus, qhov nruab nrab ntawm DC qhov chaw vuam yog cov cuab yeej tseem ceeb hauv kev tsim khoom thiab kev tsim khoom, tab sis lawv yuav tsum tau saib xyuas thiab kho qhov teeb meem kom ntseeg tau tias kev ua haujlwm zoo. Los ntawm kev daws teeb meem xws li tsis muaj vuam tam sim no, welds tsis sib xws, overheating, tswj vaj huam sib luag malfunctions, thiab ntau heev sparking, koj muaj peev xwm ua kom koj qhov chaw welder khiav smoothly thiab ntev nws lifespan. Yog tias koj ntsib teeb meem nyuaj dua, tsis txhob yig mus nrhiav kev pab cuam kom tsis txhob muaj kev puas tsuaj ntxiv thiab sijhawm poob.
