Dynamic Correction: Corrects for curved workpieces or thermal distortion—deviations that cannot be fixed by initial position detection alone.
Medium/Thick Plate Specialist: Optimized for workpieces with medium thickness or greater.
Cost-Effective Tracking: The most affordable option among all available seam tracking sensor technologies.
Minimal Interference: Requires no additional parts or external hardware around the torch, making it easier to maintain and ideal for tight workspace
Note: This sensor is not applicable for aluminum welding tracking.

This system utilizes the welding wire itself as a probe to detect the workpiece position. It is an ideal solution for manufacturers looking for a reliable, high-speed sensing method without the high costs of external laser systems.
The FD-A20 system ensures that wire deviation is kept to a minimum, significantly outperforming standard equipment. By maintaining a tighter tolerance, the system guarantees consistent contact with the joint, even in high-speed or complex application
