Dab tsi uas yuav tsum muaj kev cuam tshuam rau lub welder?

Qhov voltage yuav tsum muaj volt tsis yog ib tug -} Nkag siab cov kab sib txawv no yog qhov tseem ceeb rau kev xaiv qhov hluav taws xob zoo, ua kom muaj kev nyab xeeb thiab cov cuab yeej siv hluav taws xob. Cov ntawv no tsoo cia cov kev tsim hluav taws xob voltage rau cov txheej txheem vuam thiab cov teeb meem uas cuam tshuam rau lawv.
1. Thawj voltage: lub zog siv rau cov welder
Ua ntej dhia rau hauv vuam arc voltage, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm cov ntawv voltage (cov hluav taws xob muab rau cov kab sib chaws ntawm daim phiaj) thiab arc voltage (qhov voltage hla lub vuam arc nws tus kheej). Kev txiav txim siab thawj lub zog hluav taws xob uas txiav txim siab tias lub peev xwm fais fab siv tau, thaum arc voltage ncaj qha cuam tshuam rau weld tsim.
1.1 Cov Thawj Xaiv Cov Chaw Xaiv Hluav Taws Xob
Feem ntau cov weelers tau tsim los ua haujlwm ntawm ib qho ntawm ob qib voltage thawj:
• 110 / 120V (Tsev Neeg Tam Sim No): ME, MIG lossis Flux lossis Flubisists lossis Lub Teeb DIY SIV RAU 120V. Cov cav tov no feem ntau xa 80-140 amps, haum rau vuam nyias steel (txog rau ¼ ntiv taw) lossis txhuas. Lawv tau ua haujlwm zoo rau chav nyob hauv tsev lossis kev cob qhia tsis muaj kev nkag mus rau siab dua- voltage outlets.
• 220 / 240v (kev lag luam lossis hnyav {{2} Duty): Cov Welders (Stig, Mig, lossis Tig) rau kev siv 240V. Cov tshuab no tuaj yeem tsim 140 6}} AMPS, tab sis ntau} V yog kev sib koom tes tam sim no thiab sab saud (}
Qee qhov siab inverter welders yog "dual - voltage," hloov ntawm 120V thiab 240V. Piv txwv li, ib qho dual - voltage mig welder tej zaum siv 120v rau {} nti hlau, muab kev hloov kho rau cov haujlwm sib txawv.
2. Arc voltage: Qhov hluav taws xob uas cov duab ntawm Weld
Arc voltage yog qhov hluav taws xob ntawm electrode (lossis xaim) thiab lub hauv paus hlau thaum vuam. Nws tswj hwm arc ntev, tawm tswv yim cua sov, thiab weld hlaws duab. Tsis zoo li thawj voltage (uas yog tsau los ntawm lub zog hluav taws xob), arc voltage yog kho tau rau feem ntau cov neeg muag khoom, txawm tias nws tau ua khub (tam sim no) rau kev ua tau zoo.
2.1 arc voltage los ntawm vuam txheej txheem
Txawv vuam txoj kev muaj qhov sib txawv arc voltage:
2.1.1 mig vuam
MIG arc voltage feem ntau yog li ntawm 18-30 volts, nyob ntawm cov kab uas hla thiab cov ntaub tuab:
• Cov ntaub ntawv nyias nyias (16-18 koob ntsuas): 18-22 volts. Qis dua voltage tsim ib qho luv dua arc, txo lub ntsej muag thiab kev tiv thaiv hluav taws kub - los ntawm. Piv txwv li, vuam 18-mhawe steel nrog 0.023-nti hlau siv 18-20 volts.
• Cov ntaub ntawv nruab nrab (¼-½ nti): 22-26 volts. Ib qho ntev dua arc (siab dua voltage) nce tshav kub tawm, ua kom muaj kev sib haum tsis muaj undercut. Vuam ¼ {4 4}} nti hlau nrog 0.035-nti hlau ua haujlwm tau zoo ntawm 22-24 volts.
• Cov ntaub ntawv tuab (½ nti +): 26-30 volts. Ntau dua voltage txhawb nqa ntev ntev rau tob nkag thaum siv cov xov hlau loj (piv txwv li 0.045-nti) ntawm tuab hlau.
Mig voltage feem ntau ua khub nrog hlau pub ceev (uas tswj hwm amperage). Qhov sib npaug ntawm "voltage + cov khoom siv hlau" teeb tsa ua kom ruaj khov arc- cov hlau qis, thiab cov hlau nplaum rau hauv cov hlau hauv paus; Siab dhau, thiab sab saum toj zuj zus.
2.1.2 pas vuam (smaw)
Lo arc volcage yog qis dua, feem ntau 20-32 volts, txiav txim siab los ntawm hom electrode thiab amperage:
• 6013 cov hlau me (hlau me): 20-25 volts. Cov pas nrig no ua haujlwm nrog qis dua voltage rau kev du, qis- pias welds ntawm nyias rau me me steel.
• 7018 electrodes (muaj zog siab): 22-28 volts. Ntau dua voltage ua kom qis dua - hydrogen flux melts kom zoo, tiv thaiv porosity hauv tuab.
• 6011 cov hluav taws xob (hlau qias neeg): 24-32 volts. Ib qho ntev dua arc (ntau voltage) pab hlawv los ntawm xeb lossis pleev xim, ua rau lawv muaj txiaj ntsig zoo rau kev kho kom zoo.
Pas voltage yog tsis kho dua ntau dua li mig, raws li nws tau khi rau kev amperage. Feem ntau lo welders tso cai cia koj teeb tsa amperage, thiab voltage hloov kho tau kom muaj arc ruaj khov.
2.1.3 Tig Vuam (GTaw)
Tig arc voltage ranges los ntawm 10-20 volts, nrog kho kom meej rau cov khoom siv nyias lossis cov khoom noj:
• Aluminium (AC Tig): 14-20 volts. Ntau dua cov hluav taws xob pab tawg los ntawm txhuas cov oxide txheej, ua kom zoo nkauj fusion.
• Hlau lossis stainless hlau (DC TIG): 10-16 volts. Txo cov hluav taws xob tsim kom nruj, ruaj khov arc rau cov ntaub ntawv meej ntawm nyias hlau (piv txwv li, 16-kawg li Hlau Stainless).
Tig voltage yog kho manually ntawm lub welder tus tswj, nrog rau qhov ntev teeb meem (arc ntev) kuj muaj feem cuam tshuam txog qhov kawg voltage. Ib tug txawj ntse muab cov ntaub ntawv pov thawj 微调 voltage kom phim cov khoom, zam kev kub dhau.
3. Cov yam ntxwv uas cuam tshuam voltage xav tau
3.1 Khoom Thickness
Thicker cov hlau yuav tsum muaj siab dua Arc voltage (thiab amperage) kom ua tiav nkag mus:
• 16-lub ntsuas cua hlau (1.6mm): 18-22 volts (Mig) lossis 20-22 volts (pas nrig).
• ¼ {- nti hlau (6mm): 22-26 volts (Mig) lossis 22-25 volts (pas dej).
• 1-nti hlau (25mm): 28-30 volts (MIG) lossis 26-28 volts (pas nrog 7018 pas nrig).
3.2 electrode / Hlau Ntau
Cov hluav taws xob loj dua lossis cov xaim feem ntau xav tau hluav taws xob siab dua los yaj:
• 0.023-nti Mig Hlau: 18-22 volts.
• 0.045-nti Mig Hlau: 24-28 volts.
• ⅛ {{- nti ntawm cov: 22-26 volts.
• ¼ ¼- nti nrog cov: 26-30 volts.
3.3 chaw vuam
Ntsug lossis Nyiaj Siv Tshaj Plaws Vuam feem ntau siv cov hluav taws xob qis dua los tswj lub pas weld pas dej, tiv thaiv kev ua si rau Weld,
• Ntsug Mig Vuam: 2-3 volts qis dua li tiaj txoj hauj lwm nqis los ua kom lub pas dej me me.
• Nyiaj siv ua haujlwm Welding: 20-24 volts (vs. 22}} - - 28 volts rau tiaj tus) kom tsis txhob molten hlau dripping.
3.4 Hom (Transformer vs. inverter)
Inverter welders muaj txiaj ntsig ntau dua, kev xa tawm voltage ruaj khov txawm nyob ntawm cov chaw qis, ua rau lawv zoo tagnrho rau 120V haujlwm. Transformers, thaum ruaj, yuav tawm tsam nrog voltage ruaj khov ntawm qhov qis kawg, xav tau 240v rau kev ua kom zoo ib yam ntawm cov hlau tuab.
4. Voltage Troughooting: Cov cim ntawm cov chaw tsis raug
• Tsawg heev voltage: ARC luv luv thiab tsis ruaj khov; cov xaim / electrode lo rau hauv paus hlau; Welds muaj kev nkag tsis zoo.
• Cov voltage heev: ntau dhau lawm ncauj lus; ntev, arc ntev, ua tsis ncaj; Dav, ntiav welds nrog undercut (ib qho zawj ntawm Weld Ntug).
Piv txwv li, Mig weld nrog 16 volts rau ¼ {} nti} nti hlau yuav muaj lub zog tsis muaj zog, thaum 30 lub hau kev hlau yuav hlawv los ntawm cov khoom.
5. Cov lus qhia tswv yim rau xaiv voltage
• Ua raws cov lus qhia cov khoom lag luam: welders tuaj nrog cov npe pom zoo "voltage + amperage" chaw rau cov khoom sib txawv thiab xaim. Rau 240V Mig Welder, daim ntawv qhia yuav hais txog 22 volts {{4 4} Amps rau ¼- nti hlau nrog 0.035-nti hlau.
• Kuaj rau seem hlau: kho voltage nce rau ntawm seem (tib yam tuab li koj qhov project) kom txog thaum arc yog ruaj khov thiab weld hlaws yog khaub ncaws.
• Sib phim thawj voltage rau lub luag haujlwm: siv 120V rau kev ua haujlwm lub teeb (piv txwv li khoos phis tawj) thiab 240v rau kev ua haujlwm hnyav (piv txwv li ½ steel nkhaus).
Xaus: Voltage yog ib qho cuab yeej, tsis yog tus lej xov tooj
Qhov voltage xav tau rau ib lub voltage nyob ntawm txheej ntawm cov khoom: thawj voltage (12-32 volts muaj peev xwm, thaum arc voltage (10-32 volts) duab lub weld nws tus kheej. Mig, lo, thiab tsov txhua txhua tus muaj kev sib tw tshwj xeeb, thiab kev kho kom haum rau cov ntaub ntawv tuab, hlau / electrode loj, thiab vuam txoj hauj lwm.
Yog tsis muaj universal "yog" voltage -}} tsuas yog txoj cai voltage rau txoj haujlwm. Los ntawm kev sib txuam voltage rau koj cov txheej txheem, cov ntaub ntawv, thiab koj yuav ua kom muaj zog, tsis ua haujlwm ntawm WIY {2} {} {l;
