Choosing a Welder for Beginners: Inverter vs Transformer, MMA 200A Nutool, 160A Dedra DESI190BT

Hello, I need your help in choosing a welder for home use. I will learn how to weld, so what is the best for a beginner welder, inverter or transformer? I will show you below some welding machines that caught my attention:

which of these would you recommend the most, with what amperage to choose? If you have any suggestions or other welding machines that you can recommend, I'm waiting for hints. Thank you in advance

Basically for an amateur who only learns to weld. A different work culture. Of the above only Dedra.
Fairly solidly made. What amperage? Suitable for material. Admittedly, you always have better reserves. But you won't be welding rail tracks? Enough for all kinds of shapes and profiles.

Transformers are more resistant to conditions. Inverters are more sensitive to the working environment (dust, moisture, metal filings).

Hello,
When it comes to transformer, I don't know these models, but the vast majority of new welders at this price have an aluminum transformer winding. It's hard to weld such a welder and you need to set a high current to weld anything, because the actual current is not on the scale. I reserve, however, that I do not know if this problem is also there.

Regarding inverters dedera and nutool, according to this and other forums, in both brands of welders sit the same gutters, so no matter which brand you choose (notool is probably cheaper).

When it comes to their maximum current - I currently have a Nutool 200A welder and, to tell you the truth, I didn't need to disassemble it to a higher current like 130A and I welded a large 100mm channel with a 4mm electrode. The advantage of a welder with a higher maximum current is a higher allowable welding time with a lower current.

My experience (AS AN AMATEUR WHO LEARNED WELDING WITH THE TEST AND ERROR METHOD) is that, although the inverter ignites and holds the arc very well, the better welds came with the transformer (maybe I just haven't learned to weld well with the inverter) .

However, if I were to buy a transformer - I would definitely buy a used Polish welder (bester etc.) than a new Chinese one.

In front of the inverter I had an "Italian" Awelco transformer welder with an aluminum primary and secondary winding and at first I could not weld it - the electrode was sticking, instead of welds came out "snots" but when I learned that I had to set 1.5x more current than I should, welds they started to come out decent. One day, during the not very bothersome welding, I saw a pillar of smoke next to me and I had to buy something new. I bought Nutool NTW 202 inv and it is heaven and earth when it comes to the culture of work compared to the previous one. However, I have to train myself in welding it, because for now, the effects are slightly worse than transformer ones.

To sum up - the inverter will be better, and whether nutool 200A or deda 200A is (according to the internet) there is no difference.

And an important aspect of resistance to conditions was raised by a colleague above.

Rustic

If a colleague has a lot of money, intends to weld a lot and wants to have the equipment of a reputable company, such as: http://allegro.pl/spawarka-inwertor-bester-210-st-200a-tig-i7018848534.html. If he wants to weld a lot and does not have a lot of money, it may be one of the links that a colleague has posted. I would buy something with the greatest amperage and the lightest possible. It is a fact that for inverter transformers life is not equal to any inverter but their mass is not equal to any inverter. When it comes to the quality of welds, cheap inverters, unfortunately, in my opinion, are not for beginner welders, unless someone wants to learn to weld for several weeks and not immediately to make good welds. I know that it is possible to build an inverter that welds very well and good welds are not only a feature of transformers.

My budget for the welder is about 500-700 PLN. I intend to use it for domestic needs (hinges for doors or gates, a frame or shelves) I also have access to a power installation so there is no problem with the type of power supply. But after reading your posts I will probably decide on some inverter
