      You might wonder why I didn't list replacement liner for .023 wire. I don't think it is really needed to get reliable wire feed with 10 foot electrode lead. It does require more force to push wire through over sized liner but most welders get reliable feed without going to .023 liner. New liner is about $15. Liners are not hard to change. Liners should be removed and gun casing blown out as regular maintenance. This is needed more often with flux core wire. Again not done by most welders until they have feed problems.

            Any welding dealer selling Miller welders should have drive rollers for your welder in stock. Sears sells miller welders and should also sell drive rollers.

              b'dog...if your 190 is like my 180, it has a two groove drive roller...one groove for .030/.035, one for .023/.025, On mine, you just loosen the drive tension and lift the tension adjuster, flip the adjuster up, then push roller in and rotate it 1/4 turn, and it will pop off.. Then flip it over so the correct wire size reads on the side viewed when it is all buttoned up (which is actually the side opposite the correct groove).

                you have the roller!

                The roller that comes with it has .024 and .030 on one side and .035 on the other. At least that is what my machine came with. The two small sizes use the same groove. If you use only .035" flux-core then use the knurled roll (It has teeth). The machine can use a miller driveroll, which many welder stores may have in stock.

                  Hotfoot,

                  Recently Hobart changed the factory supplied drive roll for the Handler 140, 190, and 210 MVP. The new drive roll has an .030/.035 smooth V groove and an .030 /.035 knurled V-groove.
