Description

Technical Field

[0001] The utility model belongs to the technical field of electric welding machines, and in particular relates to a heat dissipation structure of an electric welding machine. Background Art

[0002] An electric welder uses the high-temperature arc generated when the positive and negative poles are short-circuited for an instant to melt the solder on the welding rod and the material to be welded, so that the contacted objects can be combined. Its structure is very simple, which is a high-power transformer. Electric welders can generally be divided into two types according to the type of output power supply, one is AC power supply and the other is DC power supply. They use the principle of inductance. The inductance will produce a huge voltage change when it is connected and disconnected. The high-voltage arc generated when the positive and negative poles are short-circuited for an instant is used to melt the solder on the welding rod, so that they can achieve the purpose of atomic combination.

[0003] Existing electric welding machines usually install heat dissipation devices to assist their work. However, the existing heat dissipation structure of electric welding machines generally opens holes and slots on the chassis to achieve heat dissipation. However, the heat dissipation effect of relying solely on holes and slots under high-intensity work of the electric welding machine is very unsatisfactory. Therefore, we specially designed a heat dissipation structure for the electric welding machine. Utility Model Content
