The basic principle of the arc pressure transmitter utilizes changes in the welding parameters caused by the gap between the welding torch and the workpiece to detect the torch height and left and right deviations. In the constant speed wire feeding adjustment system, the wire feeding speed is constant and the welding power is generally flat. Or descending external characteristics, in this case, the welding current will change with the arc length.
L is the external characteristic curve of the power supply. When the welding state is not chaotic, the arc working point is A0, arc length L0, and current I0. When the interval between the welding torch and the workpiece surface changes stepwise, the arc length is elongated to L1. At this time, the elongation did not have time to change, and the arc burned at the new operating point A1. The current was abruptly changed to I1, and the instantaneous change in current was ΔI1 and vice versa. From the above analysis, it can be concluded that a change in the arc position will cause a change in the length of the arc and a corresponding change in the welding current, so that the relative position between the torch and the weld can be determined. What are the types of arc transmitters? Please see below.
The arc pressure transmitter control system includes the controller and the object two major departments, in which the dynamic characteristics of the controlled object are the main ones, so the establishment of the mathematical model of the controlled object is the first step of all the work, the so-called "system modeling" Is the abstract description of the process in the software.
