There is. It’s called Lorch.I don't think there is any need with welders.
You buy it, it works. End of.
There are welders out there that are missing features they were advertised with and some that could do with having newer synergic lines added so for somebody like me a welder that offered this would be a selling point.
I suppose in the op's position paying £100 (whatever) for a usb stick to add features would sell it to him?
Some higher end machines might already offer it but I can't see many users wanting it.
I have declined at least 3 free updates on my smart tv as it does what I want as it is.
