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

Precision Wire Feeding for Industrial Applications

The Lincoln Electric KP655-1/16 Drive Roll Kit is an essential component for maintaining the performance and reliability of your industrial wire feeding systems. Designed specifically for use with 1/16-inch (1.6 mm) diameter wires, this kit is engineered to handle both cored and solid wire types effectively. In high-volume welding environments, the consistency of wire delivery is paramount to achieving sound welds and maintaining productivity. Worn or incorrect drive rolls can lead to slippage, erratic arc characteristics, and costly downtime due to wire feeding issues such as birdnesting. By utilizing genuine Lincoln Electric replacement parts, operators ensure that their equipment continues to operate at peak efficiency.

Compatibility and Versatility

This drive roll kit is tailored for compatibility with some of Lincoln Electric's most robust wire feeders, including the LN-7, LN-7 GMA, Synergic 7F, and Synergic 7FH models. These feeders are workhorses in the industry, often found in heavy fabrication shops, manufacturing plants, and structural steel environments. The KP655-1/16 kit supports a 4-roll drive system configuration, which provides superior gripping force on the wire compared to 2-roll systems. This is particularly beneficial when feeding heavier 1/16-inch wires or when using cored wires that may be susceptible to crushing if excessive pressure is applied by a single pair of rolls. The kit includes not just the drive rolls but also the necessary guide tubes, ensuring a complete overhaul of the wire path for optimal alignment.

Optimized for Cored and Solid Wire

One of the standout features of the KP655-1/16 is its versatility. It is designed to accommodate both solid MIG wires and flux-cored wires. Feeding 1/16-inch wire requires a drive roll profile that can grip the wire firmly without deforming it. This kit ensures that the wire retains its shape as it passes through the feeder and into the gun liner, promoting smooth arc initiation and stable deposition rates. Whether you are welding structural steel with flux-cored wire or performing heavy-duty MIG welding, this kit provides the traction needed to push the wire through long gun cables and complex torch angles.

Installation and Maintenance

Installing the KP655-1/16 Drive Roll Kit is a straightforward process that restores your wire feeder to factory specifications. Regular inspection of drive rolls is recommended as part of a preventative maintenance schedule. Over time, the grooves in drive rolls can wear down or become clogged with debris, reducing their effectiveness. Replacing the rolls and guide tubes simultaneously ensures that the wire enters and exits the drive mechanism in a straight line, minimizing friction and wear on the gun liner. This kit is a critical investment for any shop relying on LN-7 or Synergic 7F series feeders for their daily operations.
