Problems solved by technology
[0002] With the continuous development of industry, the application of electric welding machine is more and more extensive, but the power of electric welding machine is relatively large, and it will consume a lot of power under no-load conditions. The general electric welding machine can only manually control the power supply of electric welding machine. It is cumbersome to manually turn off or turn on the power supply of the welding machine when the welding is stopped for a short time

Description
technical field [0001] The invention relates to an electric welding machine power-saving circuit, in particular to an electric welding machine no-load self-stop power-saving circuit. Background technique [0002] With the continuous development of industry, the application of electric welding machine is more and more extensive, but the power of electric welding machine is relatively large, and it will consume a lot of power under the condition of no load. The general electric welding machine can only manually control the power supply of electric welding machine. And off, it is cumbersome to manually turn off or turn on the power supply of the welding machine when the welding is stopped for a short time. Contents of the invention [0003] The object of the present invention is to provide an electric welding machine no-load self-stop power-saving circuit in order to solve the above problems. [0004] The present invention achieves the above object through the following tech...
