realizare aparat de sudura din traf UPS

Recommended Posts

salut

am 2 trafuri de ups dintr-un ups apc sua 2200.

sunt bobinate cu folie de cupru.

credeti ca dac as inseria secundarele ar merge facut un aparat de sudura pentru home use?

in secundar am 14,5v, dar nu stiu ce curent debiteaza.

cablurile care ies din secundar sunt de 8mm

Merge, dar tensiunea de iesire este cam mica, electrodul o sa se aprinda mai greu. Aparatele de sudura au o caracteristica cazatoare, in gol au 45-55V iar in sarcina tensiunea pica pe la 28V.

Pentru acasa, cu electrod de 2,5, eu zic ca merge.

Mai bine caută două trafuri identice de cuptor cu microunde, au spațiu generos de bobinaj, unde poți băga ceva cablu gros pe post de secundar, sau platbandă de cupru. Din trafurile alea de UPS mai bine faci redresoare auto (robot ajutător de pornire).
