Lincoln Electric ST12 Seam Tracker Sensor Tip (Single Wheel)

Keep Your Seam Tracker Running at Peak Performance

Maximize the uptime of your automated welding line with the Lincoln Electric KP52042-1 ST12 Tip. Designed for the Lincoln Seam Tracker™ system, this single-wheel sensor tip is the key to keeping your torch exactly where it needs to be. Whether you are welding long structural beams or complex pipe joints, the ST12 tip rides the joint to provide accurate, real-time corrections to your welding head.

Built for the Shop Floor

We know that welding environments are tough on equipment. That is why Lincoln Electric builds these tips from plated steel, ensuring they can handle the heat and sparks of the job. The probe ends, which slide along your workpiece, are made from a special wear-resistant alloy. This means you get more arc time and less downtime waiting for maintenance. The single-wheel design (ST12) is one of over 15 standard styles available, specifically chosen for applications where a single point of rolling contact provides the best tracking stability.

Quick and Easy Replacement

Time is money in fabrication. The KP52042-1 is designed for "change-in-seconds" utility. You don't need to dismantle your entire sensor setup just to swap out a worn tip. Simply replace the low-cost tip and get back to welding immediately. This smart design protects your investment in the Seam Tracker control unit while ensuring your welds remain straight and true, shift after shift.
