Liners do need to be replaced. They get bits of copper flaking off and pull in dirt every time they're used. That's why it's important to not have too much drive roll pressure and use a wire cleaner or ear plug before the drive rolls. That said it may be difficult to find a liner since an 85 amp MIG isn't a popular machine. If you're lucky it will have a standard gun like a Tweco which will make finding a liner a lot easier. Worst case you need to get a new MIG gun but then it might be better to upgrade your machine. A big advantage in buying a name brand machine is that you'll be able to get parts and consumables down the road. [Reply]   [No Email]

Come to think about it when it stopped working I had to cut the wire off at the roll and put the wire out of the sleeve with a pair of pliers. At first it was hard to pull and then suddenly came easily. The wire may have just broken off leaving a piece of wire welded in the middle. Its encouraging about the part maybe being Tweetco. I assume the "T" logo on the liner is for Tweetco and the numbers behind it are 45-40. I normally stick weld everything but years ago I did work for a company that sold cast aluminum furniture and I bought the welder for the argon gas. It worked fine for that purpose but now I mainly use the welder for welding sheetmetal. Thanks for the info. [Reply]  [No Email]

They are good guns. Highly possible that's what the T stands for. A good welding supply should be able to get you one. You could try googling Tweco and/or the part number on it. [Reply]  [No Email]
