Umshiseli usebenza ngomgomo wenqubo yokusebenzisa amandla kagesi ukushisela izinto ezimbili ndawonye. Umshini wokushisela ikakhulukazi wakhiwa amandla kagesi, i-electrode yokushisela, kanye ne-aimpahla yokushisela.
Ukunikezwa kwamandla kweumshini wokushiselangokuvamile ugesi we-DC, oguqula amandla kagesi abe amandla e-arc. I-electrode yokushisela ithola umthombo wamandla futhi ishise impahla yokushisela ibe yisimo esincibilikisiwe nge-arc kagesi Ukuncibilika kwempahla yokushisela kwakha ichibi elincibilikisiwe elipholisa futhi liqine ngokushesha, ngaleyo ndlela kushisele ngokuqinile lezi zinto ezimbili ndawonye.
Ngesikhathi sokusebenza komshini wokushisela, ukunikezwa kwamandla kuyamiswa ngaphambi kokuba i-electrode yokushisela ishiye impahla yokushisela, futhi i-arc eyakhiwe iyacinywa. Le nqubo, evame ukubizwa ngokuthi "isikhathi sokuvala amandla," isiza i-weld pool ukuthi iphole futhi yehlise izinga lokushisa ngesikhathi senqubo yokushisela.
Umshiseli angakwazi futhi ukulawula ikhwalithi ye-weld ngokulawula yamanje kanye ne-voltage. Imisinga ephezulu ijwayele ukusetshenziselwa imisebenzi emikhulu yokushisela, kuyilapho imisinga ephansi ifanele imisebenzi emincane yokushisela. Ukulungisa i-voltage kungathinta ubude nokuzinza kwe-arc futhi ngaleyo ndlela ikhwalithi yemiphumela yokushisela.
Ngokuvamile, umshiseli ushisela izinto ezimbili ngokusebenzisa amandla kagesi ukuze enze i-arc kagesi. Ukuqina kanye nekhwalithi ye-weld kuncike ezintweni ezifana namanje, i-voltage, kanye nokukhetha kwempahla.
