Nā memo:
1. Pono e hoʻomaʻamaʻa mua ʻia ka electrode i ka mahana o 350 ° C no 1 hola.E hoʻomehana i ke koʻokoʻo ke hoʻohana ʻia.
2. Pono e hoʻomaʻemaʻe ʻia nā mea haumia e like me ka ʻōpala, ka ʻaila ʻaila a me ka makū mai ka ʻāpana hana.
3. Pono ka pōkole pōkole e hana i ka wili.ʻOi ʻia ke ala weld haiki.
