Description

Technical Field

[0001] The utility model relates to the field of argon arc welding machines, in particular to an argon arc welding machine which is convenient for heat dissipation. Background Art

[0002] Argon arc welding machine is a machine that uses argon arc welding, which uses high voltage breakdown to start the arc. Argon arc welding, or tungsten inert gas shielded arc welding, refers to a welding method that uses industrial tungsten or active tungsten as an infusible electrode and inert gas as a shield, referred to as TIG. It is generally used for welding thin plates of 6 to 10 mm and single-sided welding and double-sided forming of thick plates.

[0003] After searching the patent document with the announcement number CN220259822U, the patent document discloses "a argon arc welding machine that is easy to dissipate heat. This device drives the heat dissipation box to move through the electric guide rails on both sides. When the heat dissipation box moves, the fan inside it moves together with the heat dissipation box, so that the fan dissipates heat to the entire argon arc welding machine body through the heat dissipation through-holes on the right side, so that the high-temperature gas inside the argon arc welding machine body is discharged through the heat dissipation through-holes on the left side, and the discharged high-temperature gas contacts a plurality of metal square tubes to cool them down; compared with the prior art, this design can dissipate heat and cool down the entire interior of the argon arc welding machine, and to a certain extent can improve its heat dissipation effect, thereby extending the service life of the argon arc welding machine.";

[0004] There are two common types of heat dissipation, one is water cooling and the other is air cooling. Air cooling is to extract the hot air inside the device, so that the cold air outside the device is sucked into the device to cool the inside of the device. However, it is difficult to avoid some dust and impurities adhering to the air intake filter plate during the exhaust and intake. In this way, when the above device is used for a long time, it is easy to cause the air intake filter plate to be blocked, which can easily affect the heat dissipation effect of the device.
