Problems solved by technology
Many similar products in the past, due to few anti-interference measures, it is difficult to guarantee the reliability of the welding machine
In addition, many welding machines cannot achieve the "six prevention" performances of waterproof, conductive dustproof, moisture-proof, mildew-proof, anti-corrosion, and vibration-proof
Furthermore, it is difficult to achieve 100% high-frequency arc ignition under the condition of a 10-meter-long welding torch welding cable, and there is a problem that the welding machine cannot work normally when the grid voltage fluctuation exceeds ±15%.

The invention relates to an inverter argon arc welding machine having 'six-proof' and good arc striking performance. Through a special welding machine structure design, the problems of 'six-proof' that is water-proof, conductivity-proof and dust-proof, moisture-proof, mould-proof, corrosion-proof and vibration-proof are well solved. Through a control circuit design, the high frequency arc striking success rate reaches 100% under the 10m welding gun welding cable condition, and the ultra-high grid voltage fluctuation resistant capability that the welding machine can also work under 140-27V power grid voltage is well achieved. Through implementation of multiple anti-interference circuits or measures, working stability and reliability of the welding machine are ensured. Due to the new design, performance of the welding machine is significantly superior to many similar products in the market, the welding machine has its own characteristics, and multiple control and safety performance detection and authentication requirements of argon arc welding can be satisfied. The welding machine has good performance, so that the welding machine has good market adaptability, and the circuit, circuit board and whole machine structure design of the welding machine are unique.
Description
technical field [0001] The invention relates to an inverter argon arc welding machine with six preventions and good arc starting performance, belonging to the technical field of inverter welding machines. technical background [0002] At present, the competition in the product market of inverter argon arc welding and hand arc welding dual-purpose machines is very fierce, which is not only reflected in the advancement and advantages of technology, but also largely depends on the functions and design of welding machines. [0003] In the domestic and foreign markets, the rated current of small MOS tube and IGBT tube inverter argon arc welding machines is usually at the level of 80~200A (load duration 100~15%). Different products have different control circuit schematic diagrams, circuit board structures, and overall machine structure designs. There will also be great differences in product performance, reliability, manufacturing process and cost. For many similar products in ...
