Description

Technical Field

[0001] The utility model relates to the technical field of argon arc welding machines, and more specifically, particularly relates to an argon arc welding machine for welding stainless steel products. Background Art

[0002] Argon arc welding machine is a machine that uses argon arc welding, which adopts the arc starting method of high-voltage breakdown. Argon arc welding, also known as tungsten inert gas shielded arc welding, refers to a welding method that uses industrial tungsten or active tungsten as a non-melting electrode and inert gas as protection. In the processing of stainless steel products, stainless steel needs to be welded, so argon arc welding machine can be used for welding operations.

[0003] However, there are various types of argon arc welding machines in the prior art. For example, utility model patent CN218476135U relates to an anti-deviation argon arc welding machine, which is provided with an argon arc welding machine housing, and a welding gun is installed on the side wall of the argon arc welding machine housing; a welding machine plug is provided at the lower end of the side wall of the argon arc welding machine housing, and a welding circuit is plugged into the welding machine plug; a circuit connection port is installed on the side wall of the welding gun, and the end of the welding circuit is connected to the circuit connection port; a welding head is installed at the output end of the welding gun, and an anti-deviation guide plate is installed at one end of the outer wall of the welding gun close to the welding head, and a stabilizing mechanism is installed at both ends of the welding head on the side wall of the anti-deviation guide plate; a wheel frame is installed at the end of the stabilizing mechanism, and a rubber roller is installed in the wheel frame; the anti-deviation argon arc welding machine can prevent the staff from performing long-term straight-line welding and deflection during hand-held welding, thereby improving the efficiency of straight-line welding.

[0004] Although the argon arc welding machine can prevent deviation during long-term straight welding, it will generate a large amount of harmful smoke during welding. If it cannot be removed, it will be exposed to the working environment. The smoke is easy to enter the body with the worker's breathing during welding, causing damage to the health. In order to avoid this phenomenon, it is very necessary to design an argon arc welding machine for stainless steel products. Utility Model Content

It is introduced into the filter box by the conveying effect of the guide pipe. At the same time, it passes through the filter box to filter and purify the incoming harmful smoke, and the dust contained in the harmful smoke is filtered out. At the same time, the harmful substances contained in the smoke are purified and removed, thereby timely removing the harmful smoke to avoid exposure of the smoke to the working environment during welding, and preventing it from entering the body with the workers' breathing and causing damage to their health.
