Default how to rewire NEMA 18-20 specifically W X Y Z to NEMA 10-50 plug/socket?

Hi everyone,

I have a forklift charger, it's plug has 4 flat pin and 3phase power 250v 30A rating(written on the plug).

Upon checking it seems to be a NEMA 18-20 type, I cannot find this socket in my country and planning to rewire it to NEMA 10-50.

What does the meaning of W X Y and Z?
I know W-white
X and Y - hot wire
Z is what? where is the ground?
