Lub arc yog mos thiab ruaj khov, tsis tshua muaj txaws, zoo nkauj sib sau, zoo slag tshem tawm.
Tsawg qis, thiab muaj cov txheej txheem vuam zoo heev.
-60 ℃ qis kub cuam tshuam kev ua tau zoo heev.
Cr-Mo steel series vuam cov ntaub ntawv thiab electrode surfacing vuam cov ntaub ntawv yog dav siv nyob rau hauv roj av refining khoom.
