( TIG ARC SENSOR FD-TR )
Automatic seam tracking in TIG welding
* Allows arc length constant control (vertical tracking) in TIG.
* Allows stable execution of welding by keeping the arc length constant to the thermal distortion of thin plate.
* Allows high-accuracy tracking even in pulse TIG welding.
* Easy to use from the viewpoints of interference of workpieces and maintenance, because it requires no additional parts around the torch.
