Why is it this way?

Why on some machines, especially mig, does it have a digital display and an accurate readout but some have a number dial 1-10. A millermatic 252 has the digital but the 211 has the 1-10 settings. I find it is very difficult to set the machine especially using the Miller app. Why is it like bat and is their some way of knowing what it truly is.

Jody made a way of finding out what the wire speed is and how to get the voltage (in the same ballpark) I don't recall the title of that specific video.
Hope this helped

On machines that don't have the WFS and volt settings I use the door chart to get close - I adjust based on what I see.
The chart follows pretty normal established info.
When using machines with WFS and volts on the dial, then I go by that.
Edit:
I should also add that it's likely a cost thing as well.
The door chart on my older Millermatic 210 mig says it's for an input of 230 volts ac.
My shop gives 247 volts input so the chart setting are a little hot. I just turn it down a little.
If the machine had digital voltage and WFS displays, there would have to be circuitry that corrects for differences in input voltage to ensure the outputs matched the dials.
