Ko ngā whakamahana koiri tuwhera he whakamahana hau e whakaatu tika ana i te horahanga mata o te huānga whakamahana ki te hau. Ko te kōwhiringa o te koranu, ngā ine, me te ine waea ka whiriwhiria rautakitia hei waihanga i tētahi otinga ritenga i runga i ngā hiahia ahurei o tētahi tono. Ko ngā paearu tono taketake hei whakaaro ko te pāmahana, te hau, te pēhanga hau, te taiao, te tere o te arawhata, te auau huringa, te wāhi ā-tinana, te hiko e wātea ana, me te roa o te wā whakamahana.

NGĀ PAINGA
Te tāutanga ngāwari
Tino roa – 40 putu, neke atu rānei
Tino ngāwari
He pae tautoko tonu e whakarite ana i te pakari tika
Te roa o te ora ratonga
Te tohatoha wera ōrite

Ngā Taunakitanga

Mō ngā whakamahinga i roto i te taiao makuku, ka tūtohu mātou i ngā huānga NiCr 80 (kōeke A) hei kōwhiringa.
He 80% Nikara me te 20% Konupora (kāore he rino i roto).
Mā tēnei ka taea te whakahaere i te pāmahana whakahaere mōrahi o te 2,100° F (1,150° C) me te tāutanga ki ngā wāhi ka kitea pea te hauhautanga i roto i te paipa hau.
