KP3979-3 - Lincoln Electric 5/64 Inch Wire Guide Assembly

Reliable Wire Feeding with Lincoln Electric KP3979-3

The Lincoln Electric KP3979-3 Wire Guide is a critical component designed to maintain the efficiency and reliability of your welding wire feeding system. Engineered specifically for 5/64 inch (approximately 2.0 mm) welding wire, this guide plays a pivotal role in directing the consumable from the spool, through the drive rolls, and into the welding gun liner. In industrial welding environments where consistency is key, using the correct size wire guide is essential to prevent feeding issues that can lead to costly downtime and weld defects.

Manufactured to Lincoln Electric's exacting OEM standards, the KP3979-3 ensures a perfect fit with compatible wire feeder models. Its precise internal diameter is tailored to 5/64" wire, providing just enough clearance to allow smooth movement while restricting lateral play. This balance is crucial; a guide that is too loose can cause the wire to wander or buckle (bird-nest) under the pressure of the drive rolls, while a guide that is too tight creates excessive drag, straining the feed motor and potentially shaving the wire surface. By maintaining optimal alignment, this component protects the integrity of the wire and ensures a stable arc at the contact tip.

Durability is a hallmark of Lincoln Electric parts, and this wire guide is no exception. Constructed from high-quality materials, it resists the wear and grooving often caused by the constant friction of moving wire. Over time, worn guides can develop sharp edges or oval-shaped holes that disrupt feeding. Replacing your wire guide with a genuine KP3979-3 restores your system to factory performance levels. Whether you are running solid MIG wire or heavy-duty flux-cored wires, this guide supports the smooth delivery required for high-quality fabrication.

At Josef Gas, we understand that the smallest components often dictate the success of a welding operation. The KP3979-3 is an investment in process stability, helping you avoid the frustration of erratic feeding and the expense of wasted wire. Ensure your equipment operates at peak efficiency by choosing genuine Lincoln Electric replacement parts for your maintenance needs.
