Description

Technical Field

[0001] The utility model relates to the technical field of spot welding machines, in particular to a spot welding machine with a protective effect. Background Art

[0002] A spot welder is a mechanical device that uses the principle of double-sided, double-point overcurrent welding. Two electrodes pressurize the workpiece, creating a certain contact resistance between the two metal layers under the pressure of the two electrodes. When the welding current flows from one electrode to the other, a thermal weld is formed at the two contact resistance points, without damaging the internal structure of the welded workpiece. Spot welders are widely used in fields such as metal processing, automotive manufacturing, and electronic equipment manufacturing. Their high efficiency and automation have led to their widespread application in various industries. However, current spot welders still have the following shortcomings:

[0003] For example, patent document CN213764415U discloses a spot welding machine that can perform both multi-point welding and single-point welding, and the switch between the two is very convenient, making it easy to promote and use. However, the spot welding process generates a certain amount of smoke and sparks, which are not only harmful to the human body but also pollute the processing environment.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a spot welding machine with protective effect is proposed. Utility Model Content
