Lincoln LN-25X Wire Feeder – P/N K4267-1

The Lincoln LN-25X wire feeder (P/N K4267-1) solves field wire feed problems through CrossLinc technology and an industrial four-roll MAXTRAC wire drive. Structural steel erectors and shipbuilders lose productive hours dragging fragile 14-pin control cords across jobsite decks or walking back to power sources to adjust voltage. This heavy-duty suitcase feeder transmits voltage and wire feed speed adjustments directly through standard welding cables, giving operators full control over arc parameters right at the weld joint.

The heavy-duty four-roll MAXTRAC wire drive features precision-machined steel gears and dual spring tension arms, feeding 0.035-inch to 5/64-inch solid, cored, and hardfacing wires up to 700 IPM without slippage. A flame-retardant, high-impact polycarbonate case seals out rain, mud, and grinding grit, protecting internal 12-inch wire spools from harsh outdoor jobsite elements. The digital meter displays preset and actual voltage and wire speed, keeping field welds compliant with structural building codes.

Engine Architecture of Lincoln LN-25X

- CrossLinc Cableless Digital Technology: Communicates voltage and wire speed adjustments through the weld cable without control cords.
- MAXTRAC Heavy-Duty 4-Roll Wire Drive: Feeds solid and cored wire from 0.035 to 5/64-inch diameter without crushing or slipping.
- High-Impact Weather-Sealed Polycarbonate Case: Protects internal 12-inch 33-pound wire spools from jobsite rain, snow, and mud.
- 50-700 IPM Wire Feed Speed Range: Delivers broad speed regulation to match short-circuit, spray-arc, and flux-cored parameters.
- Internal Gas Purge and Wire Inch Controls: Primes shielding gas lines and threads new wire spools without energizing weld leads.
- Integrated Replaceable Drive Roll Inserts: Permits rapid, tool-free drive roll changes between solid and knurled wire types.

Commercial Utility Stamina & Lifespan

Engineered for harsh outdoor construction and structural steel jobs, this portable suitcase feeder maximizes welder arc-on time.

- CrossLinc eliminates control cable failures, stopping the most frequent cause of jobsite wire feeder breakdowns.
- Heavy four-roll wire drive maintains uniform feed tension through 15-foot guns, preventing erratic arc stutter and wire burnback.
- Enclosed spool chamber keeps moisture off flux-cored structural wire, preventing hydrogen-induced weld cracking.

Chassis Integration & Industrial Fitment

Measuring 15 inches high by 23 inches long and weighing 38 pounds dry, this portable suitcase feeder fits through standard shipboard manholes and hangs from structural beams.

Commercial Warranty & Field Maintenance

- Lincoln Electric covers the LN-25X wire feeder and internal MAXTRAC drive with a 3-Year factory warranty.

Blow metal dust out of the wire drive compartment weekly, check drive roll alignment pins monthly, and replace internal gun guide tubes when changing wire diameters.
