Nqe lus piav qhia: J421 yog carbon steel electrode nrog siab titanium thiab potassium txheej.Nws tuaj yeem siv rau txhua txoj haujlwm vuam nrog AC thiab DC.Nws muaj kev ua haujlwm siab vuam thiab yooj yim rau rov pib lub arc.
Daim ntawv thov: Tsim nyog rau vuam cov qauv qis carbon steel, tshwj xeeb tshaj yog tsim rau kev sib tshuam vuam ntawm me me ntawm daim hlau nyias thiab luv welds thiab npog vuam xav tau qhov chaw du.
