Embodiment Construction

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, in the present invention, descriptions such as "first", "second", "one" and so on are used for descriptive purposes only, and should not be understood as indicating or implying their relative importance or implicitly indicating the indicated technical features quantity. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

Abstract

The invention belongs to the technical field of inverter welding machine control, and provides an argon arc welding machine control circuit inverted through an IGBT. The argon arc welding machine control circuit comprises a power input module; a driving control module; an inversion output module, wherein the inversion output module is used for performing inversion output on the input voltage obtained through the power input module according to a control signal generated by the driving control module to obtain the output current of a welding machine; and an arc striking module connected with the inversion output module and used for generating high-frequency arc. The argon arc welding machine control circuit has the advantages that by selecting an SG3525 PWM modulation chip, the output current of the welding machine is more accurate; the output current value can be obtained in real time through an output current feedback unit, and when the output current value cannot meet the welding requirement, a user is reminded to conduct inspection and maintenance in time; the temperature of an IGBT tube is detected through a thermoswitch unit, so that the situation that the whole circuit is burnt out due to the fact that the temperature of the IGBT tube is too high in the welding process, and unnecessary damage is caused to a user is avoided.

Description

technical field [0001] The invention relates to the technical field of inverter welding machine control, in particular to an argon arc welding machine control circuit through IGBT inverter. Background technique [0002] Welding machine refers to an electrical appliance that provides a certain power supply for welding. Welding is widely used in various industrial fields, such as aerospace, ships, automobiles, containers, etc., due to its advantages of flexibility, simplicity, convenience, firmness and reliability, and even the same strength as the base metal after welding. [0003] At present, in the domestic and foreign markets, the sales volume of welding machines is very large, and they are widely used. In the argon arc welding machine, the quality of the welding machine will be affected by many factors, such as circuit board design, control circuit, manufacturing process, etc. These factors will eventually affect the market competitiveness of the product. [0004] At pre...
