Structural design of submerged arc welding machine

The submerged arc welding machine is composed of welding power source, welding head and auxiliary equipment. The power supply can use AC, DC or AC and DC in combination. Submerged arc welding equipment is composed of three parts: power supply, control cable and trolley. Each part is very important, and only a good cooperation can give full play to the advantages of submerged arc welding. Power requirements: The power supply is divided into AC and DC. There are magnetic amplifier type, thyristor type and inverter type for DC power supply. Because the thyristor type has moderate volume, high efficiency, reliable operation and low price, it is widely used. Features of DC power supply: stable arc, reverse polarity connection, greater penetration depth, and beautiful shape. The control cable submerged arc welding is in motion for a long time, and the cable is bent for a long time and is easily damaged. The quality of the cable is particularly important, and the welding of the cable and the plug must be reliable. There are too many examples of equipment failure due to internal disconnection of the cable, which should attract the attention of the majority of users. Trolley (welding car) The trolley is composed of an electrical control box, a motor, and a mechanical transmission device. The trolley works smoothly and reliably.
