KP2120-2 - Lincoln Electric Outgoing Guide Tube Insert .068-3/32 in

Precision Control for Heavy-Duty Welding

For professional welders, arc stability starts at the wire feeder. The Lincoln Electric KP2120-2 Guide Tube Insert is specifically engineered to handle the demands of feeding heavy wires, covering a diameter range of .068 inches to 3/32 inches (1.7 mm to 2.4 mm). This outgoing guide tube insert sits directly after the drive rolls, channeling the wire into the gun receiver bushing or cable. It is a crucial defense against feeding issues that can ruin a weld or cause frustrating downtime.

When running larger diameter wires, such as Innershield® (FCAW-S) or gas-shielded flux-cored wires, the alignment between the drive rolls and the exit path is critical. If the guide tube is worn, the wire can wander, leading to shaving or buckling. The KP2120-2 provides a tight, precision fit that supports the wire column, ensuring it enters the liner straight and true. This support is essential for preventing bird-nesting, especially when using softer cored wires or pushing wire over long distances.

Installation is straightforward, allowing you to get back to welding quickly. This insert is compatible with various Lincoln Electric wire feeders that utilize the KP2120 series guide tube system. By matching the guide tube ID to your specific wire size (.068-3/32"), you ensure optimal electrical conductivity and mechanical feeding. A guide tube that is too large offers no support, while one that is too small causes drag. The KP2120-2 strikes the perfect balance for its specified range.

Don't let a cheap or worn-out plastic guide ruin your bead. Upgrade to the genuine Lincoln Electric KP2120-2 for consistent performance. Whether you are welding structural beams, heavy machinery, or pipe, consistent wire delivery is the key to a consistent arc. Keep a spare in your toolbox to ensure your feeder is always ready for the heavy jobs.
