OVERVIEW

Lincoln LN-25 PRO One-Pak: The Ultimate Field Welding Solution

When your job site demands reliability and your schedule demands speed, the Lincoln Electric LN-25 PRO / Magnum PRO Curve 300 One-Pak (K4101-1) delivers. This all-in-one package takes the legendary toughness of the LN-25 PRO "suitcase" feeder and pairs it with the comfort and performance of the Magnum PRO Curve 300 MIG gun. Designed for ironworkers, pipeline welders, and shipyard professionals, this kit eliminates the guesswork of matching feeders with guns and drive rolls, getting you ready to weld the moment it arrives.

Built for the Toughest Jobs

The LN-25 PRO is built to withstand the punishment of construction sites and mobile fabrication. Its case is not only flame-resistant but also incredibly durable, protecting the internal components from drops and impacts. Inside, the Maxtrac® Wire Drive System uses a heavy-duty cast aluminum mechanism to feed wire smoothly, preventing the bird-nesting and slipping that can ruin a weld and waste valuable time. Whether you are running flux-cored wire on a high-rise or MIG welding in a fab shop, this feeder provides the consistent performance you need to pass x-ray quality checks.

Precision and Control

Control is everything in welding, and the LN-25 PRO gives you plenty of it. The Dual Range Wire Feed Speed dial allows for precise adjustments, giving you total command over your deposition rate. For long days under the hood, the Trigger Interlock Switch allows you to weld without holding the trigger continuously, reducing hand fatigue and improving overall comfort. The included Magnum PRO Curve 300 gun is lightweight and balanced, further reducing strain during out-of-position welding.

Ready to Weld Out of the Box

Why buy components separately when you can get everything in one click? The K4101-1 One-Pak includes:

  • LN-25 PRO Feeder: The standard for portable wire feeding.
  • Magnum PRO Curve 300 Gun: 15 ft cable, comfortable grip, and industrial-grade consumables.
  • Drive Roll Kit: Setup for .040-.045 cored wire, perfect for structural steel.

Invest in equipment that works as hard as you do. The Lincoln LN-25 PRO One-Pak is the reliable partner you need for your next project.
