K1733-5 - Lincoln Electric K1733-5 Automatic Wire Straightener for MAXsa 29 and NA-5

Precision Feeding with the Lincoln K1733-5 Wire Straightener

In the world of automatic welding, precision is everything. Even the most advanced robotic or hard automation system can be compromised by a simple variable: the curve of the wire. The Lincoln Electric K1733-5 Wire Straightener is the professional solution to this common problem, designed to ensure your wire feeds straight and true, every time. Specifically built for the Lincoln MAXsa® 29 and NA-5 automatic wire feeders, this accessory is a must-have for shops performing Submerged Arc or heavy-duty MIG welding where wire positioning is critical to weld integrity.

Wire coming off a spool or drum naturally wants to coil back up—a property known as cast and helix. When this curved wire is pushed through a welding gun, it drags against the liner and exits the contact tip at an angle. This "wandering" wire can miss the joint root, cause lack of fusion, or result in an erratic arc. The K1733-5 solves this by forcing the wire through a three-roll system that irons out the memory. The result is a wire that acts like a straight rod, aiming exactly where your automation system intends it to go. This level of accuracy is non-negotiable for long seam welds on beams, tanks, or pipes.

Versatility is a key feature of the K1733-5. It isn't limited to a single wire size; it handles a broad range from 1/16 inch all the way up to massive 7/32 inch (5.6mm) diameter wires. The integrated pressure adjustment knob puts you in control, letting you dial in the perfect amount of straightening force. Too much pressure on soft wires can flatten them, while too little on thick wires won't remove the cast. The K1733-5 gives you the tactile feedback and fine control needed to find the sweet spot for any consumable you are running.

Beyond weld quality, this straightener saves you money on maintenance. Curved wire acts like a saw inside your contact tips, wearing them out into oval shapes quickly. By straightening the wire before it enters the gun, you drastically reduce this wear, keeping your contact tips in service longer and reducing the downtime associated with changeovers. Rugged, reliable, and easy to install, the Lincoln K1733-5 Wire Straightener is the silent partner in your welding setup that ensures your heavy-duty automation runs smoothly, shift after shift.
