Re: 220VAC generator & 220VAC welder

I would have expected a welder described as "XXX Amps" to give XXX Amps
on the output, but 50 amps seems a ridiculously low output for a welder
that could be used on anything bigger than jewellery.

It's only 30 amps according to the Amazon listing but I wonder if this
adapter does do almost exactly what the OP asks for it to do?
 <https://www.amazon.com/dp/B0DQDR7F77>
Can he plug the welder male (NEMA 6-50P) into the female (NEMA 6-50R)
of the adapter, and then the male (NEMA L14-30P) of the adapter into the
female (NEMA L14-30R) of the generator? I see two potential issues that I'm not the one to explain.
1. There are 4 wires on one side but only 3 wires on the other side
2. There is a potential for 50 amps on one side but only 30 on the other
The amperage can probably be controlled. But can the wires be controlled?
I have no idea. It seems dangerous to me. What's the other wire doing?
Since one side is four wires and the other side is only 3 wires, what do you think they did with the fourth wire? Connect it to ground?
I don't know how it's wired internally though but it's UL listed.
I guess that means it's perfectly safe (it's ETL listed also).
