K1733-1 - Lincoln Electric Wire Straightener for 10-Series Feeders

Achieve Smoother Wire Feeding with the Lincoln K1733-1

Every welder knows that the key to a consistent, high-quality weld often starts before the arc is even struck—it starts with how the wire feeds. The Lincoln Electric K1733-1 Wire Straightener is designed to tackle one of the most common frustrations in MIG and Flux-Cored welding: wire cast. When wire comes off the spool, it naturally wants to retain a curve (cast) and a twist (helix). This curvature causes friction inside your gun liner, leads to premature contact tip wear, and causes the wire to wander as it exits the tip. The K1733-1 solves this by mechanically straightening the wire before it enters the cable, ensuring it feeds dead-straight for precise targeting and a stable arc.

This accessory is a perfect match for your Lincoln 10-Series wire drives. Whether you are running heavy flux-cored wire for structural steel or large-diameter solid wire for manufacturing, this straightener can handle the job. It is rated for cored wire up to 1/8 inch (3.2mm) and solid wire up to 3/32 inch (2.4mm). The ability to mount it directly to your drive or separately gives you the flexibility to set up your station exactly how you need it. If you are working with long gun cables or complex automation setups, a wire straightener is often the secret ingredient to eliminating feeding issues.

Installation is straightforward and hassle-free. The bushings on the K1733-1 are designed to match the standard incoming and gun receiver bushings you likely already use. This means you don't have to hunt for obscure adapters or modify your feeder to get it to fit. Once installed, you can adjust the straightening tension to dial in the perfect feed. By removing the cast, you ensure the wire makes consistent contact with the tip, which improves conductivity and reduces micro-arcing inside the tip that causes burn-backs.

Investing in a K1733-1 is investing in uptime. By reducing drag and liner friction, your consumables last longer, and you spend less time troubleshooting bird-nests or erratic arcs. It is an essential tool for professional welders who demand precision and reliability from their equipment, especially when running heavier gauge wires that are prone to feeding resistance.
