43115 - Bernard Style 43115 Replacement Liner 15ft .035-.045

Fix Your Feed: 15ft Liner for Bernard Style Guns

Is your wire stuttering? Are you feeling drag in the gun cable? It might be time to swap out your liner. The GEN43115 is a tough, reliable replacement liner designed to fit Bernard style MIG guns, including the Q-Gun and S-Gun series. If you are running .035" or .045" wire through a 15-foot cable, this is the part you need to get your machine running smooth again. A bad liner is one of the most frustrating things in welding—it ruins your rhythm, messes up your bead, and can even cause the wire to burn back into the tip.

This liner is built from strong coiled steel, designed to take the abuse of a shop environment. It acts as the highway for your welding wire, guiding it safely from the feeder all the way to the contact tip. When a liner gets old, it fills up with shop dust and metal shavings, acting like sandpaper against your wire. By installing a fresh GEN43115, you reduce friction and ensure that the wire speed you set at the machine is exactly what you get at the puddle. It’s perfect for running standard solid wire (ER70S-6) or flux-cored wire in 300A to 400A setups.

Installation Tips:

• Lay it Flat: Always lay your MIG gun cable out completely straight on the floor before removing the old liner or installing the new one. This prevents kinks.
• Measure Twice, Cut Once: This liner comes ready to fit 15-foot guns but will likely need to be trimmed at the front. Install the back end into the power pin first, push it through until it comes out the neck, and then trim it according to your gun's manual (usually flush with the gas diffuser or sticking out slightly).
• Check Your Burrs: After cutting the liner, make sure to file down any sharp edges on the cut end so the wire doesn't snag when it enters the tip.

Don't let a $20 part ruin a $1000 job. Keep a spare GEN43115 in your toolbox. Whether you are welding structural beams or fixing farm equipment, smooth wire feeding is the key to a good weld. This liner gives you the consistency you need to lay down perfect dimes every time.
