The problem with your unit is as a result of two things. The first being the power source, if the power source is not meant to support heavy equipment such as your unit then the speed which it goes at will definitely fluctuate and after a time it would drop to a slow pace.
Also the control knob which is not working could be the cause, due to the vibration of the system the inner workings of the knob could adjust itself to the lowest point as the external part doesnt work you dont see any movement on the knob.
Finally the transformer inside the unit might be bad and the symptoms which are being displayed are just pre-pack-up signs which are being displayed. Check out these three options and get back to me.
Hope this solution has been helpful?

Since the welder runs on 220, either of the hot wires can go to either of the other terminals (X or Y).. Those wires might be black, red, blue, brown.

There is a slight chance it would be white even though it is hot on the portable cord because some portable cord is used that way.

VERIFY the receptacle you connect to is wired correctely before connecting your unit to it.
