ʻO ka wehewehe: ʻO J421 kahi electrode carbon steel me ka titanium kiʻekiʻe a me ka uhi pālolo.Hiki ke hoʻohana ʻia no ka wiliwili kūlana āpau me AC a me DC.Loaʻa iā ia ka hana kuʻekuʻe kiʻekiʻe a maʻalahi ke hoʻomaka hou i ke arc.
Noi: He kūpono no ka wiliwili ʻana i nā hale kila kalapona haʻahaʻa, ʻoi aku ka maikaʻi no ka hoʻopili ʻana i nā ʻāpana liʻiliʻi o nā papa lahilahi a me nā wili pōkole a me ka uhi kuʻi ʻana e koi ana i nā ʻili laulima.
