Kev piav qhia: J421 yog cov hlau carbon electrode nrog cov titanium thiab potassium txheej siab. Nws tuaj yeem siv rau txhua qhov chaw vuam nrog AC thiab DC. Nws muaj kev ua haujlwm vuam siab thiab yooj yim rov pib dua arc.
Daim Ntawv Thov: Haum rau kev vuam cov qauv hlau uas tsis muaj carbon ntau, tshwj xeeb tshaj yog haum rau kev vuam ib ntus ntawm cov phaj me me thiab cov vuam luv luv thiab kev vuam npog uas xav tau cov nplaim du.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
