4. Shock sensor function
In the Arc welding system, a welding torch may collide with a workpiece or jig, resulting in its deformation,
or the robot body may get damaged. To avoid such an accident, this welding torch has the shock sensor
function, which stops the robot motion immediately when excess force is applied on the torch tip (nozzle
part), by keeping the nozzle part away and outputting the excess force detection signal at a time.
(* However, this function does not guarantee the torch positioning accuracy. After the shock sensor was
activated, ensure the torch aiming point.) (See the section 5.2.)
