I noticed it in a nearby store and was impressed (but also skeptical) by its low price! The craftsman who had worked with it was very satisfied. He even emphasized that it is one of those things you buy "with closed eyes" with so much confidence!!! Anyway, having my reservations (cheap meat is eaten by dogs, as the saying goes), I received it and... I got stuck with the welds!!! So far, I have finished half a box of electrodes and without being a top professional, it immediately helped me and as soon as I found the right amperage, it's great. Very lightweight, excellent performance, it doesn't feel anything from prolonged use at high temperatures, it easily handles the 2.5mm electrode at 70A, and now it only needs to prove its durability over time. I will come back with updates around Easter when I have to tidy up some ironwork at the country house. Happy New Year to everyone with good health.

Update 30/12/2020
It continues to work perfectly and flawlessly, I have consumed about 10 kilograms of electrodes and it remains flawless. Even in heavy iron constructions, it did not feel tired. The short cables are still a downside, but you get used to it because it is so lightweight that you can easily move it around and work comfortably.
