Basic Components of Mid-Frequency Spot Welding Control Device

Mid-frequency spot welding machines do not typically use welding materials or protective gases. Therefore, under normal circumstances, apart from the necessary power consumption, there is almost no additional consumption, resulting in lower operating costs. The control device includes a program ... Read More

Factors Affecting the Distance Between Spot Welds in Mid-Frequency Spot Welding

The spacing between spot welds in mid-frequency spot welding must be designed reasonably; otherwise, it will affect the overall welding effect. Generally, the spacing is around 30-40 millimeters. The specific distance between spot welds should be determined based on the specifications of the work... Read More

Adjusting the Specification of Mid-Frequency Spot Welding

When using a mid-frequency spot welding machine to weld different workpieces, adjustments should be made to the peak welding current, energization time, and welding pressure. Additionally, it’s important to select electrode materials and electrode dimensions based on the workpiece structure... Read More
