Miilermatic 185......

Look real close at the rollers, they are marked for the diameter of the wire.
Make sure they match the wire that you are using.
Will check the rollers. Might just pick up the remaining feeder parts when we go to town on Wednesday, the Napa I deal with is just down the road from a Miller dealer....

.023 wire in an .035 liner?

Sorry, just a guess. I'm really new to the whole welding deal.
Nope, both are .023.
It had this problem before I replaced the liner. It had the original liner in it with .035 wire. Kind of hard to weld with it when the wire is floating around a bit....
