Integrated Design of power and control cabinet, the bottom of cabinet body is provided with universal wheel, which can move at will. Positioning the welding machine coordinate by moving the shelf. Using seven-inch color touch screen, human-computer interface intuitive, easy to find parameters, modify and verify. Using Siemens PLC (Programmable logic controller) , can save at least 99 process parameters, easy to query and call. Each parameter can be used immediately after adjustment or modification, or saved after modification. Software can be updated and modified; strong anti-interference. The welding process of the welding machine is controlled by a microcomputer and completed automatically according to the pre-set procedure. Welding machine has four ways: A, welding a layer, not filling line B, welding a layer, filling line C, welding two layers, not filling line, not filling two layers of wire. The welding machine does not rotate and can be welded continuously.
