OLELO HOOLAHA:
1. Pono e hoʻomoʻa ʻia nā electrodes ma lalo o 350-400 ℃ no hoʻokahi hola ma mua o ke kuʻi ʻana, e hoʻokomo i loko o kahi pahu insulation a hoʻopili koke i ka wā e pono ai.
2. Pono e hoʻomaʻemaʻe ʻia nā stains ma ka weld e like me ka rust, a pono e hoʻomaʻamaʻa ʻia ka weld ma kahi o 200 ℃.
3.Weld hiki ke hoʻonāukiʻia ma lalo o 600-650 ℃ ma hope o ka wiliʻana i mea e hoʻopau ai i ke kaumaha o loko.
