Description

Technical Field

[0001] The utility model relates to the technical field of electric welding machines, in particular to a protective device for electric welding machines. Background Art

[0002] The electric welder uses the high-temperature arc generated when the positive and negative poles are short-circuited 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. During the use of the electric welder, a certain magnetic field will be generated around the welder. When the arc burns, it will radiate to the surroundings. The arc light contains infrared, ultraviolet and other light species, as well as harmful substances such as metal vapor and smoke, so sufficient protective measures must be taken during operation.

[0003] Electric welders are often needed during mine construction. Generally, electric welders are placed directly on the ground, which causes unstable placement and shaking, resulting in damage to the welders. At the same time, due to inadequate management of the construction site and the intersection of various operations, the cables are scratched and damaged by objects, which can easily lead to safety accidents and affect their service life.

[0004] Therefore we make improvements to this and propose a protective device for electric welding machine. Utility Model Content
