Used Lincoln Electric NA-3S wire feeder: Sell or Buy at Auction
Lincoln Electric is the world's largest welding manufacturer, with a comprehensive range of welding machines, wire feeders, and robotic welding systems. Lincoln Electric is the dominant brand in North American welding, making Lincoln equipment highly liquid in the used market with active buyer demand.
The Lincoln Electric NA-3S is an automatic wire feeder and control head for submerged arc welding (SAW). It combines a motor-driven wire drive with an analog control panel whose dials set wire feed speed and arc voltage, letting the head weld automatically as it travels along a seam on a manipulator boom, a self-propelled tractor, or a fixed weld station. The NA-3S is built for continuous, high-deposition seam welding on heavy plate rather than handheld work: it is normally paired with a compatible Lincoln DC power source, usually run in constant voltage mode, and fed granular flux from a mounted hopper so it can lay long straight or circumferential seams with no operator holding a torch. Pressure vessel fabricators, tank builders, structural steel shops, and pipe mills look for this specific model because its control is simple, rugged, and well understood: buyers add SAW capacity, or drop a known-good feeder into an existing line, without paying for a new digital control system or retraining operators. KD Auctions sees steady demand for NA-3S heads, particularly when a unit sells complete with its drive motor, control box, and a matching boom or tractor mount, and Lincoln's durability reputation keeps these legacy feeders in active production across a network of 500,000+ industry contacts.

Frequently Asked Questions
What is a used Lincoln NA-3S wire feeder worth, and how do I sell one?
Value depends on the unit's age and running hours, the condition of the drive motor and analog control, and whether it comes complete with a compatible boom, tractor, or fixed-station mount and a working power source. Because those variables move the number, KD Auctions gives sellers a free AMEA-accredited, USPAP-compliant appraisal covering both orderly liquidation value (OLV) and forced liquidation value (FLV), so you have a documented figure before choosing a sale channel. From there we can place the head in a managed auction, which runs about 6 to 10 weeks from engagement to payout, or dispatch a team onsite within 48 to 72 hours when equipment has to move quickly. Commission is tailored to the engagement and quoted upfront, and most sellers pay nothing out of pocket.
How does the NA-3S differ from Lincoln's NA-4 and NA-5 wire feeders?
All three are automatic SAW heads, but the NA-3 is the original and simplest of the family. The NA-3S sets wire feed speed and arc voltage through a basic analog control, while the later NA-4 and NA-5 added more refined voltage regulation and weld-sequencing features such as controlled start and crater fill. Those later heads are still analog units, not programmable digital systems, which is exactly why shops running standard longitudinal or circumferential SAW seams often choose the NA-3S on purpose: fewer parts to fail, service knowledge that is still common in the field, and lower long-term upkeep than the more feature-heavy models.
