KP655-1/16 - Lincoln Electric KP655-1/16 Drive Roll & Guide Tube Kit for LN-7/Synergic 7F

Reliable Feeding for Quality Welds

When it comes to welding, the quality of your arc is only as good as the consistency of your wire feed. The Lincoln Electric KP655-1/16 Drive Roll Kit is designed to solve common feeding problems associated with heavy-duty welding applications. Specifically engineered for 1/16-inch (1.6 mm) wire, this kit is the perfect upgrade or replacement for your Lincoln LN-7, LN-7 GMA, Synergic 7F, or Synergic 7FH wire feeders. Whether you are running solid wire for clean, slag-free welds or flux-cored wire for deep penetration on thick materials, this kit ensures that your wire is delivered to the puddle smoothly and consistently.

Complete 4-Roll Solution

The KP655-1/16 is a comprehensive kit that includes everything you need to refresh the drive end of your feeder. It features high-quality drive rolls and matching guide tubes. In a 4-roll system, having matched rolls is crucial for distributing the feeding force evenly across the wire surface. This reduces the need for excessive drive roll tension, which can flatten cored wires or cause shaving on solid wires. By maintaining the roundness of the wire, you ensure better electrical contact at the contact tip and reduce the likelihood of burn-backs and arc instability. The inclusion of guide tubes further enhances performance by supporting the wire as it bridges the gap between the inlet and the drive rolls, preventing buckling.

Built for the Professional Welder

Professional welders know that equipment downtime is the enemy of profitability. Struggling with a wire feeder that slips or jams wastes valuable time and materials. The Lincoln KP655-1/16 kit is built to the high standards expected from Lincoln Electric, offering durability and long service life even in harsh industrial environments. The drive rolls are manufactured from hardened steel to resist wear, ensuring they maintain their grip over thousands of pounds of wire. This reliability makes them an ideal choice for shops that run continuous shifts or handle critical welding projects where failure is not an option.

Seamless Integration

Upgrading your wire feeder with the correct drive rolls is one of the most cost-effective ways to improve weld quality. This kit is designed for a perfect fit with your existing Lincoln equipment, eliminating the guesswork often associated with universal parts. The specific design for 1/16-inch wire means the groove geometry is optimized for that diameter, providing the perfect balance of grip and clearance. Whether you are repairing heavy machinery, fabricating structural components, or manufacturing pressure vessels, the KP655-1/16 Drive Roll Kit helps you keep your arc on and your production line moving.
