64-4515 - Tregaskiss Style 15ft Liner for .045-1/16 Wire

Keep Your Bead Smooth and Your Feed Steady

There is nothing more frustrating in the middle of a weld than the wire stuttering, dragging, or stopping completely. If you are fighting your machine, the problem is often hiding inside your cable. This 15-foot Replacement Liner is the fix you need for your Tregaskiss style or Lightning MIG gun. Built to handle the heavy lifting, this liner is sized perfectly for .045" to 1/16" wire, making it ideal for structural work and heavy fabrication where you need to lay down a lot of metal without interruptions.

We know that shop equipment takes a beating. That’s why this liner is made from tough, wound steel that resists kinking even when you are working in tight corners or have the cable looped around a fixture. It provides a smooth, low-friction tunnel for your wire to travel through, ensuring that what comes out of the contact tip is steady and predictable. If you have been experiencing burnback or if your wire feeder is slipping, a clogged or kinked liner is the likely culprit. Swapping it out is one of the cheapest and fastest ways to make your welder feel brand new again.

Installation Tips

Installing this liner is straightforward. Simply remove the old liner from your gun, lay your MIG gun cable out straight on the floor, and feed the new liner in until it seats fully at the front end. Because this is a 15-foot liner, it fits standard long-reach guns, but if your cable is shorter, you can easily trim the excess from the back end using a pair of side cutters. Make sure to file down any sharp edges after cutting to ensure the wire enters smoothly. It is always a good idea to keep a spare liner in your toolbox; when feeding issues strike, you don't want to be waiting on shipping while the job sits unfinished.

Don't let a worn-out $20 part ruin a $1000 job. This aftermarket liner gives you the performance of the big brands without the premium price tag. It fits 300A and 400A guns commonly found in production shops and garages alike. Get back to welding with a smooth, consistent feed and leave the frustration behind.
