But there's your contradiction/limitation.it’s more about the versatility of having a unit that does both and is easily moved around.
Welding 10mm thick and portability are at odds with each other.
I have small old dc BOC stick set (mma).
An Oxford 200a mig.
An Rtech 200a ac dc tig set.
These x3 are fairly portable, tig set less so, but 10mm would be asking a lot unless multi running mma.
