Several major factors affecting the efficiency of spot welding machines

Due to the fact that the heat generated by the resistance is proportional to the square of the passing current, welding current is the most important factor in generating heat. The importance of welding current not only refers to the size of welding current, but also to the current density.

Lithium battery spot welding utilizes high-frequency vibration waves to transmit to two metal surfaces for welding. Under pressure, two metal surfaces rub against each other, forming fusion between molecular layers. Its advantages are fast, energy-saving, high fusion strength, good conductivity, no spark, and close to cold working; The disadvantage is that the welded metal parts cannot be too thick (usually less than or equal to 5mm), and the welding points cannot be too large, requiring pressure.

The installation, maintenance, and inspection of spot welding equipment must be carried out by electricians. When the welding machine and circuit malfunction occurs, the power should be immediately cut off and the electrician should be notified for repair. When using AC spot welding machines, the following requirements should be followed: when connecting multiple welding machines, the three-phase load should be balanced, and there must be switches and fuse protectors on the primary line.
