Abstract

The utility model discloses a no-load, no energy-consumption, high effective and energy-saving program-control welding machine which belongs to the technical field of electric welding equipment. The utility model consists of a base, a machine shell, an internal power transformer, a circuit board and a program-control discrete component. After power-on, the secondary winding of a remodeled alternating current contactor supplies program to start up power supply and charges to all electrolytic capacitors through a diode. The program-control system enters into the program automatically, cuts off the power supply of the welding machine which is then in a standby mode. In case of no welding, the welding machine has no energy consumption, thereby reaching the purpose of no-load and no energy consumption. Large-scale welding machine can no-load save energy more than 5000W; when welding is necessary, the program-control system allows various electrolytic capacitors to be in a discharging program by the commands of operators and then enters into the welding state automatically. At the same time of welding stopping, the program-control system cuts off the power supply of the welding machine automatically and then enters a standby program for the next welding automatically. A welding handle can be used for adjusting the working electric current in an upper part, which provides great convenience for remote operation and allows the novel welding machine to have obvious energy-saving effect.
