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.
