Description

Technical Field

[0001] The utility model relates to the technical field related to arc welding, in particular to an arc welding machine with a protective structure. Background Art

[0002] Electric welding machines use 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. 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] At present, electric welding equipment is widely used. Due to its heavy weight and inconvenience in movement, it sometimes needs to be stored outdoors for a long time. The electric welding machine is easily rusted by the sun and rain, and is also easily damaged by collision with foreign objects. Although current electric welding machines are generally provided with a protective casing, in order to facilitate the use of the control panel of the electric welding machine, the protective casing on one side of the control panel is generally exposed to the outside and is easily damaged, resulting in the entire electric welding machine body being unusable, causing great economic losses. In this regard, we propose an arc welding machine with a protective structure to solve the above problems. Utility Model Content
