Description

technical field [0001] The invention relates to the technical field of welding current detection, in particular to a power distribution switch welding current diagnosis system and a method for using the same, which are mainly suitable for improving the degree of intelligence and automation. Background technique [0002] Welding current refers to the current flowing through the welding circuit during welding. The unit is generally expressed in ampere. The welding current can be selected according to factors such as the type of electrode, welding position, welding level and production experience. There are two main detection methods. The first is to detect by the voltage drop of the detected current on the known resistance; the second is to detect by using the electromagnetic field established by the detected current as a standard quantity. [0003] Chinese patent, the application publication number is CN107486609A, and the application publication date is December 19, 2017. Th...
