Our automatic welding electrical system description: electrical control system is mainly controlled fixture clamping and positioning, welding start and stop the movement of the workpiece or automatic welding torch designed for the delivery device in and out, and so on. As shown, including automatic / manual conversion quality automatic welding, arc or without close control, adjust the welding speed and display, welding power switch and emergency stop switch. Electrical control system generally consists of: relay, PLC programmable logic controller, microcontroller, numerical control systems, computer control. In the welding site, due to welding spatter and more complex electrical wiring water, electromagnetic interference large automatic welding machine sale, so the relay, PLC, CNC system most commonly used. Because both the relay and PLC functions automatic welding machine, they can achieve programming control. With the advent of technology and the development of new products, and now the PLC also enables more complex functions, such as part of the CNC functions, such as circular interpolation and so on. So PLC control technology in automated welding machine has been the most widely used.
