Good morning, I had that burn back problem a while ago and also had the same liner for around 20 years. My machine is a Lincoln 255 wire matic and has been great. I run Harris wire .030 most of time with the correct liner for that wire. I have also had my liner in my machine over 20 years before having the burn back problem. My welding supplier was the one who suggested a liner change and it worked. I know a lot of guys run .030 wire in .035 liners and I wonder if that would prevent the problem. But after 20 years changing the liner and running the right sized liner seems to be the correct way to solve the problem. Have a great Thanksgiving and thanks for the "Like".Probably a good idea. That liner has been in there at least twenty years. I used to always run a lubricated wiper on the feed, but it gave up the ghost a few years back. Time to give it a little love, it's treated me well for many years, with no major issues. Mike
