Ngokumisela i-angle phakathi kwecala elingaphezulu leqonga lokugcina i-electrode kunye neqonga elijikelezayo, i-electrode inokuqengqeleka isuka kwiqonga lokugcina i-electrode ukuya kwiqonga lokubhabha phantsi kwesenzo somxhuzulane wayo. Ke, isilinda esijingisiweyo se-hydraulic kunye nenkxaso ye-oyile ye-cylinder iyasebenzisana ukuqhuba iqonga lokujikeleza ukuze lijike, ngaloo ndlela liqhuba i-electrode iphaphatheka kwiqonga lokuphaphazela. Ngenxa yokuba isenzo sokuphaphaza sixhomekeke ikakhulu kule modeli yoncedo ukunciphisa kakhulu umsebenzi wexesha lokuqhuba kunye nokusebenza ngesandla, ayithinteli nje ukunxiba kunye nokukrazula kwi-electrode ebangelwa kukuphakamisa kunye nokushukuma kwesithuthi, kodwa ikwavumela. ukusebenza okuzenzekelayo okude, ukonga ixesha kunye nomzamo, kunye nokunciphisa ukuqina kwabasebenzi.
