Ma electrode ang'onoang'ono a graphite, omwe ali ndi mainchesi kuyambira 75mm mpaka 225mm, kagawo kakang'ono ka maelekitirodi athu a graphite amawapangitsa kukhala oyenera kusungunula mwatsatanetsatane.Kaya mukufunika kupanga calcium carbide, kuyenga carborundum, kapena kusungunula zitsulo zosowa, ma elekitirodi athu amapereka yankho loyenera.Ndi kukana kwawo kutentha kwapamwamba komanso ma conductivity abwino kwambiri, ma elekitirodi athu a graphite amaonetsetsa kuti njira zosungunulira zikuyenda bwino komanso zogwira mtima, zomwe zimakuthandizani kuti mupeze zotsatira zabwino pantchito zanu.
