SI-3545-17PT - Insulated Steel MIG Liner for .035-.045 Wire, 17 ft Length

Restore Smooth Operation to Your MIG Gun

Is your wire stuttering? Are you feeling excessive drag when welding? It might be time to replace your liner. The 17-Foot Insulated Steel Liner (SI-3545-17PT) is the perfect solution for welders using .035" to .045" wire in Binzel-style equipment. Over time, MIG liners become clogged with copper dust, dirt, and debris from the shop environment. This buildup creates friction, causing the wire to slip at the drive rolls or burn back at the tip. Installing a fresh liner is one of the most cost-effective ways to instantly improve your welding performance.

This liner features a durable steel coil design that resists kinking, ensuring the wire travels smoothly even when the gun cable is bent or looped. The insulated jacket is a standout feature, providing an extra layer of protection that helps maintain consistent gas coverage at the weld pool by preventing leaks within the cable. At 17 feet long, it provides ample length for 15-foot torch assemblies, allowing you to trim it for a perfect, custom fit. A liner that is cut too short can cause micro-arcing inside the gun, while one that is too long can cause feed issues; having the extra length ensures you can get it just right.

Designed for the rigors of daily industrial use, this liner is built to last. It is compatible with standard steel wires and is an essential spare part to keep in your toolbox. Don't let a $20 part ruin a day's worth of work. Keep your arc smooth and your beads consistent with this high-quality replacement liner.

Installation Tips

• Measure Twice, Cut Once: Ensure the gun is laid out straight before measuring and trimming the new liner.
• Clean Cuts: Use a sharp pair of side cutters or a liner cutter to ensure no burrs obstruct the wire path.
• Check Drive Rolls: When changing the liner, it's a good time to inspect your drive rolls for wear as well.
