We have a similar Rohr in our Men's shed, bought by somebody who thought it was a German made machine. They were not amused when I pointed out the manual written in Chinglish!
I've used it a few times & it welds ok but the claimed output is a bit ambitious. To get it to run a 3.2 rod nicely you need it set at 150 amps (should be 90-130).
If I've more than a few tacks to do I bring in my own welder!
The one in your link claims 120a so you'll probably be limited to a 2.5 rod.
Yes 2.5mm rods would be the max I'd need anyway. I use arc occasionally for outdoor repairs off a 13amp plug such as gate hinges or light box section type fab work.
Also - my arc welder is there as a "loaner" for others! So if friends or family ask to borrow your welder give them the cheap one you don't care too much about
