The correct use of spot welding heads

Method of spot welding

When the spot welding head is not strong or the wire is brought up, the main point should be the spot welding head, not the higher parameters. When spot welding, be careful not to use too much force to grind, just use a grinding disc or W5 use fine sandpaper to lightly grind the bottom of the spot welding head for couple of times.

Do not disassemble the spot welding head frequently.

The center of the spot welding head is insulating glue. Tightening the spot welding head and then loosening it will affect the touch position of the two spot welding heads, resulting in poor welding performance. Therefore, it is strongly recommended that the spot welding head is installed and used until it cannot be used. Just take it out, do not often disassemble the spot welding head in the middle.

The clamping part of the spot welding head clamp should be clean

Due to the large current used in welding, the reason why large parameters are often required is because there are a lot of dirt where the spot welding head clamp clamps the spot welding head, which seriously affects the flow of current. Therefore, it is recommended to clean the area once a month.

To line up correctly

Defective products are generally caused by inaccurate alignment. One is that the line must pass through the two ends of the bottom end of the spot welding head, and the other is that there is an error when looking at it, and the line must be pressed at the bottom end of the spot welding head. The center position, but it appears to e where the wire is pressed behind the spot welding head.

Each spot welding head is different and cannot use the same parameters

The spot welding head is a very weak and delicate product. It has a standard range when it leaves the factory. Because different machines have different connection effects, different products have different degrees of surface oxidation, and the time the spot welding head is placed is different, and the degree of oxidation is different. Not the same.

The tolerances of each spot welding head are also different. Although they are all within the qualified range, the function of the welding spot is related to various factors such as the machine, the connection effect, the degree of oxidation of the welding surface, the condition of the line, and the strength of the foot. Therefore, the parameters corresponding to each spot welding head are different. Strictly speaking, there is no way to achieve two spot welding heads with the same welding effect, but as long as the parameters are suitable, the welding effect is in the same range or the difference is not large. As long as the above requirements are followed, the welding time of the spot welding head can be longer.
