Wehewehe: He electrode i uhi ʻia me ka titanium-potassium kiʻekiʻe ʻo J421X no nā hana wili kila kalapona. Hiki iā ia ke hana ma ke kūlana kū i lalo, a kūpono no ka wili ʻana i nā kūlana āpau me nā hana wili maikaʻi loa, a hiki ke hoʻohana ʻia no AC a me DC. He laumania a maʻemaʻe ka wili ʻana. Paʻa ka ʻāʻī a maʻalahi hoʻi e hahau hou, hiki ke wehe maʻalahi ʻia ka slag.
Hoʻohana: Pili ia i ka hoʻopili ʻana i ke kila kalapona moku a me ka papa kila galvanized, ʻoi aku hoʻi, hoʻopili i ka hoʻopili ʻana o ka papa lahilahi i kahi kūlana kū i lalo a me ka noi hoʻopili discontinuous.
