Gullco Mechanical Seam Trackers and Height Sensors are designed for use with the Gullco Kat Travel Carriage to accurately maintain the required, pre-set distance between the gun or torch and the workpiece in automated welding and cutting operations.

Three models are available to effectively meet various application needs. All are constant velocity, spring-type sensors utilizing hardened and ground slide bars with recirculator ball bushings to provide 1-3/4"(44mm) of torch float.

Other float distances available on request.

Mechanical Seam Tracker with constant velocity spring, hardened ground rods and recirculator ball bushings to provide 1-3/4"(44mm) of 45º torch float and 1-1/4"(31.75mm) of weld seam misalignment in both the horizontal and vertical plane. The assembly includes a Micro Cross-slide with gun holder to provide 3/4"(19mm) of XY adjustment. Supplied as standard with single copper guide wheel, 1- 1/8"(29mm) sq. rack box, 12"(304mm) rack arm and 1-1/8"(29mm) swivel mounting clamp for attachment to Kat Carriage rack arm.

(A) When weld seam is Below the Kat carriage level, the sensor rack arm clamp is located below the sensor rack box.

(B) When weld seam is above carriage level the sensor rack arm clamp is positioned above the sensor rack box. Additional height adjustment may be required. We recommend the use of our Rack Box Riser Assembly (below) to increase the carriage rack arm height by 2”, 4"or 6”
