Embodiment Construction

[0028] Such as Figure 1-11 As shown, the main components of the welding machine include: 1) Wire feeding part. It mainly includes: a welding wire spool 13 for gas shielded welding, a wire feeding mechanism 17, a European style gas shielded welding torch interface copper head 18 and a wire feeding control circuit part on the single board. The wire feeding mechanism 17 and the wire feeding reel shaft 13 are installed on the inner middle partition. The wire feeding mechanism 17 is close to the front panel 21 of the welding machine. The wire feeding mechanism 17 is connected with the European-style gas shielded welding torch interface copper head 18 installed on the front panel 21 accordingly. During gas shielded welding, the gas shielded welding torch is connected with the copper head 18 of the European style gas shielded welding torch interface. The welding wire is mounted on the wire spool 13. After the welding wire is installed, it can be sent into the wire feeding mechan...

Abstract

The invention relates to a structure of an IGBT (insulated gate bipolar translator) inverter welding machine with two welding functions. The inner part of the welding machine is divided into left and right side layouts, wherein parts such as circuit boards, a cooling fan and the like are arranged at one side, and parts such as a wire feeding mechanism, an electric reactor and the like are arranged at the other side. One of the two circuit boards is a display and operation control panel, six nixie tubes and display control circuits thereof are designed on the display and operation control panel; the six nixie tubes and display control circuits thereof are divided into two groups which are respectively used for displaying current and voltage parameters; and a manual welding / gas-shield welding method conversion button, a gas-shield welding 2T / 4T welding gun switch operating mode selecting button, a voltage, current and wire feeding speed unit indicator lamp, an overheat indicator lamp as well as a current wire feeding speed, voltage and electronic electric reactor inductance parameter setting and regulating potentiometer are further arranged on the display and operation control panel; and electronic parts and components are arranged on both surfaces of the other large circuit board. According to the structure, the welding method is multifunctional, the problem that single-functional welding machine is narrow in application range is solved, and the circuit principle, the circuit boards and the integral structure of the welding machine are also unique.

Description

technical field [0001] The invention relates to a single-tube IGBT inverter MIG / MAG gas shielded welding machine with manual arc welding function. It belongs to the technical field of electric welding machines. [0002] technical background [0003] At present, the competition in the inverter MIG / MAG gas shielded welding machine product market is very fierce, which is not only reflected in the advancement and advantages of technology, but also largely depends on the welding machine's circuit and its functions and structural design. . [0004] In domestic and foreign markets, the rated current of small MOS tube and IGBT tube inverter MIG / MAG gas shielded welding machines is usually at the level of 140~200A (load duration 100~35%). Most of these welding machine products have a single MIG / MAG gas shielded welding function. Its scope of application will be limited. [0005] For multi-functional gas shielded welding machines that can also use functions such as manual arc weldi...
