Problems solved by technology
However, the power device and the air duct of the traditional electric welding machine are located in the same area, that is, when the airflow flows to the air duct or flows out through the air duct, the airflow will flow through the power device, and the power device is located in the airflow environment for a long time. There will be accumulation of metal dust nearby, which will seriously affect the normal use of power devices and eventually cause damage to power devices

Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

The invention relates to an electric welding machine and a dust-proof structure of the electric welding machine, comprising: an installation body, a partition plate and a fan unit. In the dust-proof structure of the electric welding machine, firstly, the size and shape of the partition plate are determined according to the size and shape of the installation cavity. The wind device is installed in the ventilation cavity, and the power devices required by the electric welding machine are installed in the assembly cavity. When the power device is in operation, the power device will generate heat, and part of the heat will be absorbed by the separator. At this time, the airflow in a specific direction can be generated in the ventilation cavity through the operation of the fan device, and the heat absorbed by the partition plate can be cooled during the flow of the airflow, thereby realizing the cooling of the power device. At the same time, during this process, the metal dust generated by the air flow will be isolated by the partition plate, stay in the ventilation cavity or be discharged through the air outlet together with the air flow. That is to prevent metal dust from staying at the power device driven by the airflow, and avoid damage to the power device.
Description
technical field [0001] The invention relates to the technical field of electric welding machines, in particular to an electric welding machine. Background technique [0002] Most of the traditional electric welding machines have a three-plate structure or a single-plate structure. When using the electric welding machine, ventilation and heat dissipation are required, that is, an air duct is opened on the electric welding machine. However, the power device and the air duct of the traditional electric welding machine are located in the same area, that is, when the airflow flows to the air duct or flows out through the air duct, the airflow will flow through the power device, and the power device is located in the airflow environment for a long time. Metal dust will accumulate nearby, which will seriously affect the normal use of power devices and eventually cause damage to power devices. Contents of the invention [0003] Based on this, it is necessary to provide an electri...
