Description

Technical Field

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

[0002] A spot welder is a device that uses a high-temperature arc generated when the positive and negative poles are momentarily short-circuited to melt the solder on the welding rod and the material to be welded, thereby combining the materials.

[0003] During the use of the spot welding machine, the material to be spot welded is placed between the positive electrode and the negative electrode, and the positive electrode on the top is lowered. The positive electrode and the negative electrode are in contact to spot weld the material. However, when welding some materials with more complex structures, the material cannot be placed between the positive electrode and the negative electrode. It can only be placed by changing the rotation angle of the positive electrode and the negative electrode. The existing spot welding machine cannot weld and can only weld by other methods. Its use is relatively limited. At the same time, when spot welding the material, people need to hold the material until the positive electrode and the negative electrode are in contact, which will create the risk of the positive electrode and the negative electrode pressing the fingers.
