KP3807-6 - Lincoln Electric KP3807-6 AutoDrive SA Conduit Liner, 6 ft

Restore Smooth Wire Feeding with the Lincoln KP3807-6

For welders relying on AutoDrive SA Push Torches, the Lincoln KP3807-6 Conduit Liner is an essential replacement part to keep your arc smooth and your frustration low. We all know that a welding torch is only as good as its ability to feed wire. If your liner is clogged, kinked, or worn out, you're going to fight the puddle, deal with stuttering starts, and potentially ruin expensive workpieces. This 6-foot liner is the direct replacement you need to restore your torch to factory-fresh performance.

The conduit liner acts as the backbone of your wire delivery system. The KP3807-6 is specifically crafted to reduce friction, allowing the wire to glide effortlessly through the torch cable. This is particularly important in push torch setups where the column strength of the wire is tested; any resistance in the liner can cause immediate feeding problems. By installing a fresh KP3807-6, you ensure that the drive rolls transfer all their energy into moving the wire forward, rather than overcoming drag inside the cable.

Installation is straightforward, designed to fit perfectly into the AutoDrive SA architecture without the need for guessing or cutting to size in most standard configurations. Whether you are running mild steel, stainless, or other alloys, having a clean, high-quality liner prevents contamination and drag. A degraded liner can often be diagnosed by inspecting the wire for shavings or noticing a wandering arc due to inconsistent electrical contact.

Don't let a cheap or worn-out consumable compromise your weld quality. The Lincoln Electric KP3807-6 offers the durability and precision manufacturing that professional welders expect from the brand. Keep a spare in your toolbox or supply cabinet so that when feeding issues strike, you can swap it out quickly and get back to laying beads. This liner is built to withstand the rigors of daily use while providing the consistent performance required for high-quality fabrication.
