Technical Field

[0001] The utility model relates to the technical field of production of a PLC control cabinet, and more specifically, to a PLC control cabinet welding device. Background Art

[0002] PLC control cabinet is a cabinet made of steel material to protect the normal operation of components. It is widely used in chemical industry, environmental protection industry, power system, metallurgical system, nuclear power industry, fire safety monitoring, transportation industry, etc. PLC control cabinet manufacturing materials are generally divided into hot-rolled steel plates and cold-rolled steel plates. When processing the electrical cabinet, you need to build its frame structure first, and then assemble the components inside it. When the frame of the PLC control cabinet is remanufactured, each steel plate needs to be welded and connected.
