Nyob rau hauv lub ntsej muag ntawm txhua yam sib txawv ntawm cov roj teeb qhov chaw vuam tshuab, qee cov tuam ntxhab pheej yig, thiab qee qhov kim. Ntau tus phooj ywg tsis paub xaiv, vim lawv tsis to taub, qhov tseeb, lawv saib lawv tus kheej xav tau. Piv txwv li, yog tias koj xav tau los tsim high-end roj teeb pob welding, ces xaiv lub transistor chaw vuam tshuab, zoo tib yam vuam yuav tsum tsis siab dhau, koj muaj peev xwm ncaj qha manually pedal qhov chaw vuam tshuab AC pulse ntawm kab.
Nws yuav tsum tau muab sau tseg tias thaum saib xyuas txog tus nqi ntawm qhov chaw vuam tshuab ntawm txawv manufacturers, peb yuav tsum to taub lub vuam fais fab mov ntawm qhov chaw vuam tshuab. Qhov tseeb, kev lag luam tus nqi yog pob tshab, tus nqi ntawm vuam fais fab mov yog siab, thiab vuam fais fab mov kuj tseem ceeb heev, uas cuam tshuam ncaj qha rau cov txiaj ntsig zoo ntawm vuam cov roj teeb. Peb ntshai tsam ntsib cov tub lag luam phem, xws li transistor fais fab mov, tib lub transistor fais fab mov, 6000A thiab 8000A cov nqi sib txawv, qee qhov kev lag luam thiaj li yuav txo tau cov nqi, shoddy. Thaum 6000A raug muag, tus neeg siv khoom nws tus kheej raug dag.
