Iimodeli zokuwelda amabala amatsha e-Heltec zinamandla ngakumbi ngamandla encopho ye-pulse ye-42KW.Unokukhetha incopho yangoku ukusuka kwi-6000A ukuya kwi-7000A.Ilungiselelwe ngokukodwa ukuwelda ubhedu, i-aluminiyam kunye nephepha lokuguqulwa kwe-nickel, uchungechunge lwe-SW02 luxhasa ubhedu olutyebileyo, i-nickel esulungekileyo, i-nickel-aluminiyam kunye nezinye iintsimbi ezidityanisiweyo ngokulula nangokuqinileyo (inkxaso ye-nickel efakwe ishidi lobhedu kunye ne-nickel ecocekileyo ye-welding ngqo kwi-electrode yobhedu yebhetri, ubhedu olusulungekileyo. ishidi ukuwelda ngokuthe ngqo kwi-electrode yobhedu yebhetri ene-flux).
I-HT-SW02H ikwanakho ukulinganisa ukuxhathisa.Inokulinganisa ukuchasana phakathi kweqhekeza lokudibanisa kunye ne-electrode yebhetri emva kwe-spot welding.
