K52172-1 - Lincoln Electric Seam Tracker System MA-20/MP-22

Automate Your Precision with Lincoln Electric

For professional welders and fabricators running automated lines, the Lincoln Electric K52172-1 MA-20 Control and MP-22 Probe System is the ultimate solution for "set it and forget it" welding performance. We know that in the real world, perfect fit-up is rare. Beams have camber, plates warp under heat, and fixtures can slip. This seam tracking system acts as a relentless guide, physically feeling the joint and adjusting your torch position on the fly so you don't have to constantly hover over the slide controls.

The kit combines two powerful components: the MA-20 Control box and the MP-22 Probe. The MP-22 is a rugged, heavy-duty sensor that mounts near the torch. It uses a replaceable tip to ride along the joint, detecting even slight deviations in the seam's path. It sends this information instantly to the MA-20 Control, which commands your motorized slides to move up, down, left, or right. The result? The arc stays exactly where it needs to be, right in the root, regardless of how the part moves or distorts during the welding process.

This system is particularly valuable for long, continuous welds found in structural steel, tank manufacturing, and shipbuilding. It supports high-deposition processes like Submerged Arc and Flux-Cored welding where visibility is often limited or where the operator cannot safely be close to the arc. By installing the K52172-1, you reduce the risk of costly defects like lack of fusion or undercut caused by wandering arcs. It transforms a standard automated setup into a smart, adaptive welding machine.

Installation is straightforward for those familiar with Lincoln Electric automation gear. The components are designed to withstand the shop environment, resisting dust, grime, and impact. When your production schedule demands high volume and flawless consistency, relying on manual adjustments isn't enough. Upgrade your rig with the MA-20 and MP-22 system and experience the confidence of fully automated, precision tracking.
