That is actually a "feature" of some Miller machines now. (My Millermatic 140 is one of them.) The wire feed starts at a lower speed when you first pull the trigger, then quickly ramps up to your set wire speed after a second or so. I hate that feature because it screws up MY timing!
The first time I used the machine I thought the drive motor/controller was defective and I contacted Miller about it. The tech I talked to said it is supposed to do that to help prevent sticking the wire on arc starts. The amount of delay changes (milliseconds) depending on your set wire speed. Every MIG welder I have used (including my MM 185) up until this machine has been "instant on, full wire speed" as soon as you hit the trigger so that is what I am used to. Had I known the 140 has this built in delay, I never would have bought it.I just wanted a more portable 110V MIG welder at the time.

Wire speed has a scale for the wire size, and the heat knob has two scales, one material size, the other standard heat ranges 3.0 3.5 and so one to 10.0.
Using AUTO set, wire size selected, dial in the material size and burn away, that the way the 140 works?
Would you know if the slow feed rate when an arc is struck. Is a feature of both manual and AUTO set modes?
If only in AUTO set there might be a way to adjust or turn that feature off. My guess if happening in both modes, you could be stuck with that.
Below example is an older Miller with AUTO set. It shows how to gain better control of the AUTO set configuration. Maybe a glance thru the manual could turn up something similar for ya. I am all for automation .. but sometimes they take it to far for my taste
Thanks for the heads up on a new feature on that machine . thumbs UP!
