The Lincoln LN-25 PRO Standard Wire Feeder (K2613-5) is a heavy-duty portable industrial wire feeder that accepts spools up to 45 lb, feeds wire diameters from .023 in. to 1/16 in., and operates across-the-arc on any CV power source delivering 15–110 V DC — no separate control cable required. It pairs with the Lincoln Flextec, Ranger, Vantage, CV, and Idealarc welder families, making it one of the most versatile suitcase feeders on the jobsite.

The LN-25 PRO is Lincoln Electric's flagship portable wire feeder for heavy industrial and field welding. Its across-the-arc power design means no separate control cable is needed — the feeder draws power directly from the welding arc, giving crews maximum portability without tethering to a control box.
- Structural fabrication and field erection: The rugged, flame-resistant case and 45 lb spool capacity keep ironworkers productive without frequent spool changes on large structural weldments.
- Pipeline and heavy construction: The dual-range wire feed speed delivers precise low-end control for root passes and fill passes on pipe, while the 450 A / 60% duty cycle handles sustained heavy deposition rates.
- Shipbuilding: Compatibility with a wide wire diameter range — from .023 in. solid steel up to 3/32 in. cored wire — lets shipyard crews run multiple wire products from a single feeder.
- Engine drive generator applications: Pairs directly with Ranger and Vantage engine-driven welders for remote pipeline or infrastructure work where utility power is unavailable.
- General and heavy fabrication shops: When paired with a CV power source such as the Flextec or Idealarc, the LN-25 PRO functions as a dependable benchtop or cart-mounted feeder for production MIG and flux-cored work.
The LN-25 PRO Standard (K2613-5) is an across-the-arc feeder powered entirely by the welding arc voltage — any machine that delivers 15–110 V DC at the output studs can drive it. Lincoln Electric's recommended power source families include:
- Flextec Family — multi-process CV/CC power sources ideal for pairing with the LN-25 PRO in fabrication shop environments.
- Ranger Engine Drive Welders — portable engine-driven generators for remote field use.
- Vantage Engine Driven Welders — heavy-duty engine drives for pipeline and structural work.
- CV Family (Classic CV, Idealarc CV) — traditional constant-voltage power sources used in shops and light industrial applications.
- Idealarc Family — Lincoln's long-running CV/AC transformer-rectifier line, compatible across the full voltage range.
Because no control cable is needed, the LN-25 PRO works with any compliant third-party CV power source as well, provided it supplies 15–110 V DC at the studs. Browse compatible wire feed welders and power sources to find the right match for your application.
