Description

technical field

[0001] The invention relates to the technical field of electric welding machines, in particular to an inverter welding machine control circuit. Background technique

[0002] The control circuit of the inverter welding machine in the prior art includes a main control circuit and an output circuit, and the main control circuit is connected with the output circuit. The inverter welding machine using the control circuit with the above structure has the following disadvantages: when the welder is welding, especially at the moment of starting the arc, the electrode is easily stuck to the workpiece, making it impossible to continue welding. This not only interrupts the welding, thereby affecting the welding efficiency, but the short circuit between the two will directly lead to equipment damage or accidents that threaten personal safety. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a control circuit ...
