Ithafa likagesi litholakala ezindaweni ezimbili: insimbi engagqwali ye-201 kanye ne-aluminium. Ingxenye yensimbi engagqwali igqokwe nge-Teflon, okwenza kube nokusebenza ngaphandle kokugcinwa futhi kuhlinzeka ngempumelelo yokuhlanzeka engcono.
Kukhona imodi eziningi zezimboni zamandla kagesi, kuhlanganisa ne-high-low voltage, i-full high voltage, kanye ne-dual-high single-low voltage. Ukuxhumana kwamandla kungafezwa ngeziphakamiso zokuxhumana noma ngezixhumi ezibhalwe. Ukuze kube nokwenziwa ngokwezifiso, kukhona ukukhetha kokuthi ubukhulu, imodi, kanye nendlela yokuxhuma amandla.
