Mark is talking about the one on the right in this link.

We use both, but my son is always tapping the nozzle to get spatter out. Have not have the IMIG-200 short yet. But we spend some time cleaning out the nozzle.

Mike,
That's the one.

Thanks for all this information, I think it has solved a problem that I thought I was having with my Millermatic. Only on this machine the wire stops feeding. if I had good stick out, I would put the wire right against the work piece to insure I would be starting in the right place, I could always see just a tiny spark when I touched it. Mine is a transformer based welder so it's not just the inverters that do it. I was always dumbfounded why it would act like it overheated after just a few tacks or inches of weld on a 40 degree day and other time it would weld on it's highest settings longer than I could. I am glad you are all willing to share your experiences on issues that seem like they should be common sense. (especially without the berating comments)
