Electricity saving control circuit of electric welding machine

Abstract

The invention discloses an electricity saving control circuit of an electric welding machine. The electricity saving control circuit of the electric welding machine comprises a first transformer, a second transformer, a current transformer, first to ninth resistors, first to sixth capacitors, a first diode, a second diode, a third diode, a fourth diode, a fifth diode, a sixth diode, a first time base chip, a second time base chip, a first relay, a second relay, a rectifier and a main switch. The electricity saving control circuit only can automatically cut off a power supply when the electric welding machine is idle, and can automatically access the power supply in operation, so that excellent electricity saving effect is achieved in actual operation, and the electricity saving control circuit has the advantages of low power consumption, convenience for operation, simple actions, sensitivity, reliability and strong practicability; and meanwhile, the electricity saving control circuit has the effects of few used elements, low cost, reduction of production cost and facilitation of promotion and application.

Description

technical field [0001] The invention relates to an auxiliary device of an electric welding machine, in particular to an electric welding machine power-saving control circuit. Background technique [0002] The electric welding machine is one of the indispensable welding tools at the construction site, but in the actual use process, the no-load time of the electric welding machine even exceeds the operating time, and its no-load loss is generally about 200W, which is not only in vain A lot of electric energy is wasted, and the power factor of the power grid will be reduced. In severe cases, it may even cause electric shock and casualty accidents for workers. In order to save electricity, the manual on and off will obviously affect the work efficiency. Load loss is of great practical significance. At the same time, the high-tech electric welding machines controlled by electronic circuits in recent years have good power-saving effects, but they have high requirements for the wor...

[0002] The electric welding machine is one of the indispensable welding tools at the construction site, but in the actual use process, the no-load time of the electric welding machine even exceeds the operating time, and its no-load loss is generally about 200W, which is not only in vain A lot of electric energy is wasted, and the power factor of the power grid will be reduced. In severe cases, it may even cause electric shock and casualty accidents for workers. In order to save electricity, the manual on and off will obviously affect the work efficiency. At the same time, the high-tech electric welding machines controlled by electronic circuits that have appeared in recent years have good power-saving effects, but they have high requirements for the working environment and require regular maintenance. The cost is too high and it is difficult to promote
