Description

Technical Field

[0001] The utility model relates to the technical field of electric welding machines, in particular to an electric welding machine with a dust collection structure. Background Art

[0002] The 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 as to combine the contacted objects. 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. They use the high-voltage arc generated when the positive and negative poles are short-circuited for an instant to melt the solder on the welding rod, so that they can achieve the purpose of atomic combination.

[0003] Electric welding machines will produce a lot of harmful substances such as metal vapor and smoke when in use, and the dust needs to be cleaned in time. However, current electric welding machines are basically not equipped with devices to absorb these harmful substances. Long-term use will have a certain impact on physical health and the environment, which is not environmentally friendly and healthy. Utility Model Content
