The seam tracker consists of a precision
Sensor, controller and slide. The sensor does probe the weld seam and the controller does control the change calue on the work-piece.
The welding torch is guided rapidly and exactly by moving the slides.
The seam tracker can calibrate the error caused by the work-piece deformed itself and the welding heat.

There si a stop function to prevent the deviation of the sensor from a thin work-piece. So, the welding defect can be avoided.
The seam tracker can be compatibly used with other automatic system or unmanned system.

All the controlling is done in digital and program, so the unit does show the good performance in the tough environments.
The seam tracker has the function for sensing the tack welding.
A uniformed welding bead is produced. There is the function to make the time of weld end programmed because the tracker can sense the edge of work-piece.

There are several priority functions as well as the reverse tracking.
The tracker has the right/left reverse function for easy installation.
The tracker has the function to prevent the deviation of the sensor from the welding seam. If the deviation occurs on the seam, the tracker stops automatically.

The tracker can work on the other semi or full automatic system.
All the functions are programmed for easy control.
