Kev piav qhia: J421X yog lub electrode uas muaj titanium-potassium-coated ntau rau kev siv vuam hlau carbon. Nws tuaj yeem ua haujlwm hauv txoj haujlwm ntsug, thiab tsim nyog rau txhua txoj haujlwm vuam nrog kev ua tau zoo heev, thiab tuaj yeem siv rau ob qho tib si AC thiab DC. Lub vuam du thiab huv si. Lub arc ruaj khov thiab yooj yim rov ntaus, slag tuaj yeem tshem tawm yooj yim.
Daim Ntawv Thov: Nws siv rau kev vuam cov hlau carbon thiab galvanized steel phaj thiab, tshwj xeeb, siv kev vuam ntawm cov phaj nyias nyias hauv txoj haujlwm ntsug thiab daim ntawv thov vuam tsis tu ncua.
