Miller syncrowave 250 with a three phase plug?

I know there are a few threads that say the syncrowave is only single phase and so does the manual so I believe them but I was just given one and it has this plug on it. I'm not an electrician but I do know the basics and a four prong plug like that usually means three phase right? Can I just remove that one and put on a different one?

Where is the ID plate located? I looked around it and couldn't find anything. I couldn't find the cereal number ether. Its from my work, they upgraded and said I could take it if I wanted but have no info on it because it hasn't been used in a few years.

I know my cereal number is cap'n crunch. lol

but its always been located by the power entrance to the machine.
and yes they have made 1ph and 3ph machines,no they are not interchangeable unless the plate specs it out on it. most were only one or the other.

I prefer ciniman toast crunch haha
I actually found the plate. We moved and it was placed up against the wall so I couldn't properly see the front but I found it and it is in fact single phase. So why the four prong plug?
