Ok machine arrived today, in manual mode how to you select ampage vs wire speed?
Just a little research, personally I didn't know this

So there is no amperage control on mig welders it's a combination of wire speed and stick out, voltage is constant at a given setting
From the above then wire speed and amperage are linked, voltage is constant
Don't think this will help your situation but at least it shows the theory behind mig welding
