Sengoliloeng sena se bua ka potso ea hore na mochini oa tjheseletsa oa maqhubu a mahareng a maqhubu a motlakase o hlahisa tlhahiso ea hona joale (DC). Ho bohlokoa ho utloisisa mofuta oa tlhahiso ea motlakase bakeng sa ho lekola ho lekana ha mochini oa welding bakeng sa lits'ebetso tse ikhethileng le ho ntlafatsa ts'ebetso ea welding.
- Molao-motheo oa Ts'ebetso: Mochini oa welding oa "medium frequency inverter spot welding" o sebetsa ho latela molao-motheo oa ho fetola phallo ea alternating current (AC) hore e be tlhahiso e tobileng ea hona joale (DC) ka potoloho ea inverter. Potoloho ea inverter e kenyelletsa likarolo tse kang li-rectifiers le li-filters tse laolang sebopeho sa wave wave.
- Ts'ebetso ea Pulsed: Maemong a mangata, mechini ea welding ea maqhubu a mahareng e etselitsoe ho fana ka pulsed hona joale nakong ea ts'ebetso ea welding. Pulsed current e bolela sebopeho sa maqhubu moo nako ea hona joale e fapanyetsanang pakeng tsa maemo a holimo le a tlase, e leng se hlahisang phello ea pulsating. Ketso ena ea pulsing e ka fana ka melemo e fapaneng, ho kenyeletsoa ho fokotsa mocheso, taolo e ntlafalitsoeng holim'a ts'ebetso ea welding, le ho fokotseha ho fokolang.
- Karolo ea Direct Current (DC): Le ha mochini oa welding oa maqhubu a mahareng o fana ka pulsed hajoale, o boetse o na le karolo e tobileng ea hona joale (DC). Karolo ea DC e etsa bonnete ba hore ho na le arc e tsitsitseng ea welding mme e kenya letsoho mosebetsing oa ho tjheseletsa ka kakaretso. Ho ba teng ha karolo ea DC ho thusa ho boloka botsitso ba arc, ho khothaletsa nako e telele ea li-electrode, le ho thusa ho kenella ka mokhoa o tsitsitseng oa weld.
- Taolo ea Liphetho: Mochini oa welding oa sebaka sa maqhubu a mahareng o lumella ho lokisa maqhubu a pulse, nako ea pulse, le amplitude ea hajoale, ho fana ka taolo holim'a ts'ebetso ea welding. Mekhahlelo ena e feto-fetohang e thusa basebelisi ho ntlafatsa maemo a welding ho ipapisitsoe le thepa, tlhophiso e kopaneng, le litšobotsi tse lakatsehang tsa weld.
Mochini oa tjheseletsa oa maqhubu a mahareng a maqhubu a mahareng hangata o hlahisa hona joale ka karolo e tobileng ea hona joale (DC). The pulsed current e fana ka melemo mabapi le taolo ea ho kenya mocheso le boleng ba weld, ha karolo ea DC e tiisa litšobotsi tse tsitsitseng tsa arc. Ka ho fana ka maemo a feto-fetohang ha ho lokisoa li-parameter tsa pulse, mochini oa welding o nolofalletsa basebelisi ho fihlela taolo e nepahetseng mabapi le ts'ebetso ea welding. Ho utloisisa litšoaneleho tse hlahisoang ke mochini ho bohlokoa bakeng sa ho khetha li-parameter tse nepahetseng tsa welding le ho eketsa boleng le katleho ea welding.
