Abstract
The invention discloses a gas shielded welding control circuit and a gas shielded welding machine. It includes a voltage supply module, a voltage regulation module, a waveform control module, a current regulator, a pulse width modulation circuit, a drive circuit, a current feedback module and a voltage feedback module connected to each other; the waveform control module includes a first resistor, a second resistor, a third Resistor, fourth resistor, fifth resistor, first diode, second diode, first anti-reverse connection unit, second anti-reverse connection unit, first capacitor, second capacitor, first operational amplifier, first A power supply and a second power supply, by arranging a first anti-reverse connection unit, a second anti-reverse connection unit and a second capacitor in the waveform control module, first charge the first capacitor, and when charged to the second anti-reverse connection unit leads When the first capacitor is turned on, the first capacitor and the second capacitor are charged; when the first anti-reverse connection unit is turned on, the second capacitor also participates in the discharge process, the capacity of the capacitor becomes larger, the discharge becomes slower, and the current rise speed becomes slower, so, Optimized arc characteristics.
Description
technical field [0001] The embodiments of the present invention relate to the field of welding technology, in particular to a gas shielded welding control circuit and a gas shielded welding machine. Background technique [0002] Gas shielded arc welding is referred to as gas shielded welding or gas electric welding. It is a fusion welding that uses an arc as a heat source and gas as a protective medium. During the welding process, the shielding gas forms a gas protective layer around the arc, which separates the arc and molten pool from the air, prevents the influence of harmful gases, and ensures the stable combustion of the arc. It is widely used in the welding field. The performance of short-circuit current in gas shielded welding directly affects the arc characteristics. [0003] However, the current performance of the short-circuit current in the gas shielded welding process is not conducive to the stability of the arc. Contents of the invention [0004] Embodiments...
