Abstract

The invention relates to a three-function inverter welding machine with high electromagnetic compatibility. The three-function inverter welding machine has the functions of manual welding, argon arc welding and MIG / MAG gas shielded welding. The inside of the welding machine is designed into a left-right structure; a circuit board and a cooling fan are arranged at one side of the welding machine; a wire feeding mechanism is arranged at the other side of the welding machine; the circuit board is divided into three blocks, namely a filter board rectifier bridge and power-on buffer circuit board, a display and operation control circuit board and a main control circuit board, and according to the circuit functions, the circuit board mainly comprises an input filtering circuit, a power-on buffer circuit, an inverter main circuit, a switching power supply circuit, an IGBT (Insulated Gate Bipolar Translator) driving circuit, a gas shielded welding wire feeding and electromagnetic gas valve control circuit, an output current and voltage detection and feedback control circuit, a welding gun switch detection circuit, given, feedback and PI control and PWM output characteristic control circuit of three welding methods, a rapid spot welding control circuit, a display and operation control circuit and an overcurrent and overheat protection control circuit. According to the welding machine, multiple welding methods are achieved, the operation interface is good, and the problems of electromagnetic compatibility and reliability of the welding machine are well solved.

Description

technical field [0001] The invention relates to a three-function inverter welding machine with high electromagnetic compatibility. The welding machine has high anti-interference or electromagnetic compatibility and reliability. One machine has multiple functions and can be used for manual arc welding, argon arc welding, and MIG / MAG. Gas shielded welding is used for welding; it belongs to the technical field of inverter 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 foreign markets, the rated current of IGBT inverter MIG / MAG gas shielded welding machines is usually at the level of 160~650A (load duration 100~35%). Most of such welding machine products have a single MIG...
