Kusankha kwa aloyi, miyeso, ndi waya woyezera kumasankhidwa mwanzeru kuti apange yankho lopangidwa mwamakonda kutengera zosowa zapadera za pulogalamuyo. Zofunikira zoyambira kugwiritsa ntchito zikuphatikizapo kutentha, kuyenda kwa mpweya, kuthamanga kwa mpweya, chilengedwe, liwiro la ramp, kuchuluka kwa njinga, malo enieni, mphamvu yomwe ilipo, ndi moyo wa chotenthetsera.

Malangizo

Pakugwiritsa ntchito pamalo ozizira, tikupangira zinthu za NiCr 80 (grade A) zomwe mungasankhe.
