WeldingCity Steel Conduit Liner 35-40-15 (.030-.035) 15-ft for Lincoln Magnum 100L and Tweco Mini/No.1 MIG Welding Guns

MiG welders have liners through which the welding wire is pushed. Eventually from an accident or old age the liners need to be replaced. Any t kink or sharp protrusion in the liner prevents the wire from moving smoothly to the welding gun. I realized this when my Lincoln Weld-Pak 155 started sputtering-out the welding wire. I disassembled the exterior casing from the interior wire drive mechanism and after loosening the set screw at the base pulled the liner out. The 35-40-15 .030-.035 liner I purchased from WeldingCity.com was an exact match after I trimmed it down to the length I needed. It installed easily with no difficulty. (INSTALLATION NOTE: if you trim the liner or need to cut it make sure that there is no sharp point in the liner that can snag your welding wire. File down is necessary.) My wire fed welder now runs smoothly. I found the cost of this replacement liner fair and its construction to be similar to the original from Lincoln.

All ok it was a liner no prob

The product was a exact fit, exactly as described. Welder is back running good again, will be returning for more products.

Liner works perfectly in my Lincoln Pro-Mig 175 with the Magnum 100L gun. Easy to replace and my issues have disappeared. EDIT: I also purchased the 45-40-15 (.035-.045) liner for another gun I have with the same great results.

Fits fine - plenty of length to spare.

Works great

worked great fit like oem parts

Fits perfectly to my Lincoln 180 welding machine!

Easy installation on my older Lincoln Weld Pak 100 with a Magnum 100L gun. There is a slight difference on the copper head (Welder end) with this new one being slightly shorter and the rubber O-ring in a different location but it still installed correctly and works well. I bought my welder at a pawn shop so I cant verify if the older liner is correct or not. Final test when using the new liner shown it works well with .030 solid wire, no binding, no gas leak and good electrical continuity. I tested it with a meter before using.

works great!
