K52170-1 - Lincoln Electric MA-20 / MP-1 Tactile Seam Tracking System

Lincoln Electric MA-20 Control / MP-1 Probe System (K52170-1)

The Lincoln Electric K52170-1 MA-20 Control and MP-1 Probe System is a premier solution for tactile seam tracking in hard automation welding environments. Designed to integrate seamlessly with Lincoln Electric's automation equipment, this system provides a robust and reliable method for maintaining torch positioning relative to the weld joint. In heavy industrial applications such as beam fabrication, tank manufacturing, and pipe welding, part fit-up is rarely perfect. Thermal distortion and minor dimensional variances can cause the weld joint to shift during the process. The MA-20/MP-1 system eliminates the guesswork by utilizing a mechanical probe that physically rides in the joint, detecting changes in position and signaling the motorized slides to adjust accordingly.

The system is comprised of two main components: the MP-1 Mechanical Probe and the MA-20 Control Unit. The MP-1 probe is built to withstand the intense heat, spatter, and harsh conditions typical of Submerged Arc (SAW) and heavy-duty MIG (GMAW) welding. Its tactile tip maintains contact with the workpiece, translating physical movement into electrical signals. These signals are processed by the MA-20 Control Unit, which interprets the data and commands the cross-slides to move the welding head vertically or horizontally. This continuous feedback loop ensures that the electrode remains precisely targeted in the joint, regardless of irregularities in the material or fixture.

Implementing the K52170-1 system into your production line offers significant operational advantages. By automating the tracking process, operators are relieved of the fatigue associated with constant manual adjustments, allowing them to focus on overall process monitoring. This leads to a substantial reduction in rework and scrap caused by off-seam welds. The system's electromechanical design is favored for its simplicity and reliability compared to more complex optical or laser systems, particularly in environments where smoke or flux dust might interfere with non-contact sensors. Whether you are retrofitting an existing manipulator or outfitting a new welding cell, the Lincoln Electric MA-20/MP-1 system delivers the precision required for high-quality automated welding.
