KP2268-1 - Lincoln Electric LT-7 Drive Roll for .052-1/16 Wire

Optimize Your LT-7 Tractor Performance

Maintain the precision and reliability of your Lincoln Electric LT-7 Tractor with the KP2268-1 Drive Roll. Designed explicitly for this industry-standard mechanized wire feeder, this drive roll accommodates wire sizes of .052 inches and 1/16 inches. The LT-7 is a workhorse in heavy fabrication, known for its ability to travel along the joint and deposit weld metal with high consistency. However, the performance of the entire tractor system relies heavily on the condition of its consumables and wear parts. The drive roll is the primary interface between the machine's motor and the welding wire; therefore, its condition is directly linked to weld quality.

Over time, the grooves on drive rolls can wear down, leading to a loss of traction. This slippage can cause the wire feed speed to fluctuate, resulting in burn-backs, stubbing, or uneven penetration. The KP2268-1 is built to resist this wear, crafted from high-grade steel that maintains its dimensional integrity even after feeding thousands of pounds of wire. The precise groove geometry is designed to grip the wire firmly without crushing it, ensuring that the wire retains its shape as it enters the contact tip. This is particularly important for flux-cored wires where crushing can deform the flux column, and for solid wires where surface damage can accelerate liner wear.

This product is sold individually, but please be aware that the LT-7 feeder mechanism generally utilizes a pair of drive rolls to establish the necessary feeding force. When performing maintenance, it is best practice to inspect both rolls and replace them simultaneously if significant wear is detected to ensure balanced feeding pressure. Keeping a spare set of KP2268-1 drive rolls on hand is a smart strategy for any shop utilizing LT-7 tractors, minimizing downtime during critical production runs.
