   • Shongwe yepamusoro yeiyo iripoElectrodechikara muchoto(Iye anodakutsiva) yakagadzirirwa. Simba rinodzimwa, uyeElectrodeChikamu chinowanzo kumutswa. Chero chero dumbu rasara reNipple kubva kune iyo yakambopedzwa chikamu chikamu ingangoda kubviswa.
   • Zvekare, zvese socket tambo pane iyo iripo electrode yekamuri uye iyo nipple tambo (uye socket tambo kana nipple yakaparadzaniswa) paElectrode nyowani inofanira kunyatsonatswa.Mhepo yakamanikidzwa inowanzo shandiswa kuputika chero guruva,graphitezvidimbu, kana marara. Kunyangwe zvidiki zvidiki zvinogona kukanganisa nematehwe akakodzera uyekuwedzeramagetsikuramba.

2. Kuwedzera ("Kuwedzera" iyo Electrode):

   • The theNew ElectrodeChikamu chinonyatso kusimudzwa uye chakamiswa zvakananga pamusoro pekhorosi iripo.
   • Izvo zvakaderedzwa zvishoma nezvishoma, chichiita kuti zviumbwe zvakakwana, saka tambo dzisina musoro dzinobata zvakanyatso neSocket tambo dzekhoriyamu pazasi. Kuyambuka-kusimuka kunofanirwa kudzivirirwa pane zvese zvinodhura sezvo zvichikanganisagraphiteuye inodzivirira kubatana kwakachengeteka.
   • The theNew Electrodeinozotenderera (kazhinji muchina) kusimbisa kubatana.

3. Kuruba:

   • Kamwe ruoko-takasimba (kana muchina-snug), nyanzvi, calibrated torque wrench system inoshandiswa kushandisa iyo chaiyo yekupedzisira torque yakataurwa neTorque yakatsanangurwa neElectrodeMugadziri. Izvi zvimwe inonyanya kukosha nhanho.
   • Torque yakaringana inovimbisa yakakwanakusanganakudzvanywa pakati peElectrodezviso uye nipple, kuderedzakurwisa kwemagetsiuye kuwedzera simba simba rekubatana kwejoini. Torque diki inotungamira mukunatsa uye kusunungura; Torque yakawandisa inogonakupengathe theElectrodesocket kana nipple.

4. Cheki yekupedzisira:

   • Kuongorora kwekuona kunosimbisa kubatana kunogara zvakanaka uye kwakabatanidzwa.
   • Zvishandiso zvekusimudza zvinobviswa.
   • The theElectrodeChikamu chinogona kubva kudzikiswa kumashure, uyechoto kuvhiyainogona kutangazve kamwe kwakachengeteka.
