I’m giving up on my crappy MAG welder and looking for something simple for welding 5-10mm mild steel. I can get a 120A inverter with Hot Start, Arc Force and Anti-Stick for an acceptable price, what can I expect from this device?

22A input on a recommended 16 fuse ? 5KVa on 1.5 cable ? Whats the duty cycle ? 3.2 rod on 120A I doubt it. 2.5 would be the best option. Fine for light work but as you have mentioned 10mm, you will struggle. The numbers do not add up. A cheap inverter of this power should be about 100euros. Noel.

120A is a bit limiting, and even then it has 20% duty cycle,which could get very tedious if you’re on a big job.

Actually it’s 85Eur so cheap is the magic word. The next bigger (160A) is almost twice as expensive, and I don’t know if it will be used enough to justify the expense.
