  • What Liner?

    I purchased a MM175 and it came with a small (2#?) roll of solid .024 wire. When I picked up a tank filled with C25, I also grabbed a large (11#?) roll of solid .030 wire. My question is, do I need to purchase a new liner for the .030 wire? My thinking is that since Miller supplied a roll of .024, then the liner they supplied me is a .023/.025 liner. I noticed on their webite that they list three liners for my machine: .023/.025, .030/.035, and .035/.045

    I'm thinking I'm going to need one of the .030/.035 liners to be able to use my large spool of wire. Can anyone confirm?

    You should be set to go with the liner that came with the welder, which probably is the .030/.035. I have run .023/.030/.035 through my HH140, and it has the same gun.

      When I got my MM175 a couple of years ago - I immediately installed a 11# spool of .030 solid wire and a .030 contact tip and was off and welding.

        The MM 175 comes from the factory with an .030/.035 liner installed in the gun. So you'll be fine with the .030. BTW, I've never had any wire feeding issues running an .023 wire though this liner either.
