The Lincoln Electric Wire Drive Roll Kit — KP2268 series is purpose-engineered for use with the Lincoln Electric LT-7 subarc wire drive and similar large-feeder platforms requiring matched drive roll components. Covering wire diameters from .045–.052 in (1.2–1.3 mm) through 3/32–3/16 in (2.7–4.7 mm), the KP2268 kits support submerged arc (SAW), large-diameter MIG/GMAW, and flux-cored (FCAW) applications where heavy-gauge wire feed consistency is critical to weld quality and deposition efficiency.
Sold in pairs (2 rolls required per set), the KP2268 drive rolls are matched to the LT-7 feeder's roll seat geometry and drive pressure requirements. Consistent wire feed in high-amperage submerged arc and large-diameter FCAW applications directly affects bead profile, deposition rate, and weld integrity — making correctly sized, factory-matched KP2268 rolls an essential maintenance component for production SAW and heavy FCAW operations.
- KP2268-1 – LT-7 Drive Roll .052-1/16 in (1.3-1.6 mm) (2 required)
- KP2268-2 – LT-7 Drive Roll .068-3/32 (1.7-2.4 mm) (2 required)
- KP2268-3 – LT-7 Drive Roll 3/32-3/16 (2.7-4.7 mm) (2 required)
- KP2268-4 – LT-7 Drive Roll .045-.052 in (1.2-1.3 mm) (2 required)
- Matched for Lincoln Electric LT-7 wire drive — direct-fit replacement with no feeder modification
- Wire diameter coverage: .045–.052 in through 3/32–3/16 in (1.2–4.7 mm) — spans medium to large SAW and FCAW wire sizes
- Sold in pairs — each kit supplies the two rolls required for proper LT-7 drive operation
- Supports SAW (submerged arc), heavy FCAW (flux-cored), and large-diameter GMAW processes
- Precision-machined groove profile — maintains wire feed accuracy at the high wire speeds required by submerged arc applications
- Durable roll construction — withstands the sustained feed forces of high-amperage production SAW operations
- Submerged arc welding (SAW) on structural plate, pressure vessels, and pipe
- Heavy FCAW (flux-cored) production welding with large-diameter cored wire
- Shipbuilding and offshore structure fabrication using LT-7 feeder systems
- Bridge and infrastructure plate welding with SAW processes
- Pressure vessel and heat exchanger fabrication requiring high-deposition welding
Lincoln Electric KP2268 drive roll kits are the factory-matched replacement component for LT-7 wire drives in SAW and heavy FCAW applications — ensuring the precise feed force, groove geometry, and roll sizing that high-amperage production welding demands. Selecting the correct wire-diameter-specific pair maintains the feed consistency that submerged arc and large-diameter flux-cored processes require for reliable, high-quality weld deposition.
