Lincoln Liner Spring .062in(1.8mm) inner diameter .156in(4mm) outer diameter 1.13inlong KP2009-10

Q: What does the Lincoln Liner Spring .062in(1.8mm) inner diameter .156in(4mm) outer diameter 1.13inlong KP2009-10 do, and why does it matter for weld quality?

The liner guides wire from the drive rolls through the gun cable to the contact tip. A worn or kinked liner is the most common cause of erratic wire feeding, birdnesting, and burnback. Replace the liner when wire feeding becomes inconsistent, when switching wire diameters, or every 3–6 months in production use regardless of visible condition.

Q: When should I replace the Lincoln Liner Spring .062in(1.8mm) inner diameter .156in(4mm) outer diameter 1.13inlong KP2009-10?

Liner inside diameter must match your wire diameter — use a liner sized for your wire: .023–.030 in wire uses a small-bore liner, .035–.045 in wire uses a standard-bore liner, and 3/64–1/16 in wire uses a large-bore liner. Installing an oversized liner causes wire to wander and arc erratically; an undersized liner causes excessive friction and burnback.

Q: What size or specification do I need for the Lincoln Liner Spring .062in(1.8mm) inner diameter .156in(4mm) outer diameter 1.13inlong KP2009-10?

Cut the liner to the exact length specified for your gun model. A liner that is too long buckles inside the gun neck and blocks the wire path; one that is too short leaves an unsupported wire gap at the tip end, causing burnback. Always trim with a clean, square cut — not diagonal — to ensure the wire enters the tip bore smoothly.

Q: Is the Lincoln Liner Spring .062in(1.8mm) inner diameter .156in(4mm) outer diameter 1.13inlong KP2009-10 an OEM Lincoln Electric part?

Q: What warranty does the Lincoln Liner Spring .062in(1.8mm) inner diameter .156in(4mm) outer diameter 1.13inlong KP2009-10 carry?
