K4267-3 - Lincoln LN-25X CrossLinc Wire Feeder with Flowmeter and Tweco Connection

Industrial-Grade Portable Wire Feeding Solution

The Lincoln Electric LN-25X Wire Feeder (K4267-3) represents a significant leap forward in field welding technology, specifically engineered for the rigorous demands of construction, shipbuilding, and structural fabrication. This unit is designed to solve the most common challenges faced by operators working at height or at significant distances from their power source: voltage drop and cable management.

CrossLinc Technology: Control Without Chaos

At the heart of the LN-25X is Lincoln's proprietary CrossLinc Technology. In traditional setups, adjusting voltage requires either a dedicated control cable—which adds weight, clutter, and a point of failure—or a trip back to the power source. CrossLinc eliminates this by communicating voltage control signals directly over the standard welding power cable. This means the operator maintains full control of their parameters at the arc without the safety hazard and logistical nightmare of extra cabling.

True Voltage Technology (TVT)

Long cable runs inevitably lead to voltage drops, resulting in the arc receiving less power than the machine is set to deliver. The LN-25X features True Voltage Technology (TVT), which actively monitors the voltage at the feeder. If a drop is detected, TVT automatically signals the power source to adjust its output, ensuring that the voltage you set is the voltage you get at the weld. This results in consistent weld quality and reduces the need for rework caused by "cold" welds.

Integrated Flowmeter and Rugged Design

This specific model (K4267-3) comes equipped with an integrated flowmeter, allowing for precise shielding gas regulation directly at the feeder. It also features a robust Tweco-style input connection. The unit is housed in a flame-resistant, impact-resistant case with potted PC boards to withstand moisture and corrosion, ensuring reliability in the harshest industrial environments.
