[0002] Electric welding machine is the high temperature arc produced when the positive and negative pole is in the moment short circuit to melt the welding material on the welding rod and the material to be welded, makes the contact object combination equipment. Because the high voltage assembly in electric welding machine operation power is bigger, easy produces a large amount of heat, needs the help of heat abstractor to carry out temperature control, the cooling structure of existing welding machine mainly through fan accelerates the air flow circulation inside and outside electric welding machine to carry out heat dissipation to the working part, but the static electricity of high voltage assembly is generated on the surface when running, and the dust and other impurities in the air flow are captured, which leads to the accumulation of dust inside the machine after a long time of use, and the risk of short circuit of internal electronic components is easy to occur, which is low in safety.

[0003] Through the retrieval, the patent with the announcement number CN221019069U discloses a heat dissipation structure for welding machine, which is characterized in that a plurality of first strip-shaped heat dissipation openings are arranged at equal distances on the front and back surfaces of the welding machine body, facilitating the free flow of air to cool the interior of the welding machine body. A plurality of second strip-shaped heat dissipation openings are arranged at equal distances on the left side surface of the welding machine body, and a heat dissipation fan is arranged inside the welding machine body. When the heat dissipation fan is started by the controller, it can quickly draw air into the interior of the welding machine body through the second strip-shaped heat dissipation openings, and the air that has absorbed heat can be quickly discharged to the outside through the first strip-shaped heat dissipation openings, thereby quickly cooling and dissipating heat inside the welding machine body.

[0004] In addition, the above-mentioned scheme also sets the first dust screen and the second dust screen, which can effectively reduce the dust entering the welding machine body with the air. However, if the filtering precision of the dust screen is high, it will affect the ventilation efficiency of the welding machine body, and the dust screen is easy to be blocked, with a short maintenance cycle. If the filtering precision of the dust screen is low, although it has little effect on the ventilation efficiency and prolongs the maintenance cycle, it will cause a large amount of small particle dust to enter the welding machine body, which needs to be improved.
