Best answers

Jaki spawacz inwerterowy 230V do spawania MMA, bez TIG, kupić do amatorskiego garażowego użytku za około 500 zł?

Za te pieniądze najlepiej wybrać sprawdzoną spawarkę MMA marki Dedra, Magnum albo Sherman z realnym prądem około 150–180 A, a nie sugerować się napisami 200–330 A, bo w tym budżecie to zwykle marketing [#18689474][#18688262][#18689717] Z konkretnych modeli padły propozycje Magnum Snake 200, Dedra DESI 199BT oraz — jeśli można dopłacić — Bester 170-ND, który ma wyglądać solidnie i wymaga zabezpieczenia 16 A [#18685597][#18685709][#18688262] W praktyce dla amatora takie urządzenia wystarczają, a różnice między Magnum, Sherman, Ideal itp. są niewielkie, bo często to podobna chińska baza pod inną obudową [#18689474] Warto nie wybierać zbyt małego modelu, bo trudniej go naprawić, i pamiętać o czyszczeniu wnętrza z pyłu, bo najczęściej padają tranzystory mocy i okolice [#18689474][#18689717] Trzeba też brać pod uwagę duty cycle i to, że przy wyższym prądzie spawanie nie będzie ciągłe [#18689257][#18689717]

And one more thing MOSFET or IGBT transistors are more likely to perform, failure rate etc.?

I have IGBT welders - at least I think so. It was discussed here: https://www.elektroda.pl/rtvforum/topic1557369.html

DEDRA DESi201M/200A - this was the choice , quite good opinions, and a 4-year warranty! At the 130A setting, the 3.25 electrode goes like a storm...

Topic summary

✨ The discussion revolves around selecting a 230V MMA inverter welder within a budget of PLN 500 for amateur use. Participants recommend various models, including MAGNUM SNAKE 200, Dedra DESI 199BT, and WELD MASTER 330A, while emphasizing the importance of reliable current ratings and duty cycles. Concerns are raised about the quality of low-budget welders, particularly regarding the components used, such as transistors and potentiometers. Users share experiences with different brands, noting that many welders are manufactured in China and that performance can vary significantly. The consensus suggests that for amateur applications, models with a real current output of around 160A are adequate, and users should be cautious of exaggerated specifications. The Dedra DESI201M/200A is highlighted as a solid choice with good reviews and a four-year warranty.
