Precision spot welding machine is mainly used to weld precision workpieces, so do you know the advantages of precision spot welding machine? The following editor of Huandian will introduce the advantages of precision spot welding machine to you:
First, the welding effect is good, the time adjustment resolution of precision spot welding machine can reach 0.25ms (4kHz inverter frequency), and the control accuracy is high. The response speed of feedback control of precision spot welding machine is significantly accelerated, and the output stability is good. The output current of precision spot welding machine is pulsating DC, and it is continuous DC output under the action of loop inductance, with high thermal efficiency and stable welding heat input.
Second, the welding molding is good, the precision spot welding machine is DC output, the heating is concentrated, and the welding time is shortened. Therefore, the effect is very good in strong standard welding, the traceless effect is first-class, and the computer case and other high-end welding can be directly welded.
Third, it is energy-saving and environmentally friendly, the transformer of precision spot welding machine works at a higher frequency (1-4kHz), the loss is very small, the DC output improves the power factor, and the energy-saving effect is obvious.
Fourth, the equipment has a reasonable structure and is easy to install. The transformer of the precision spot welding machine is greatly reduced, and the equipment is relatively light.
The spot welding machine adopts the principle of double-sided double-point overcurrent welding. When working, the two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, an instantaneous heat welding is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the two workpieces to this electrode to form a loop, and the resistance welding machine motor industry application will not damage the internal structure of the welded workpiece.
Resistance welding machine motor industry application method:
1. When welding, the position of the electrode rod should be adjusted first, so that when the electrode just presses the weldment, the electrode arms remain parallel to each other.
2. The selection of the current adjustment switch level can be selected according to the thickness and material of the weldment. After power-on, the power indicator light should be on, and the electrode pressure can be adjusted by adjusting the spring pressure nut to change its compression degree.
3. After completing the above adjustments, you can turn on the cooling water first and then turn on the power to prepare for welding. The procedure of welding process: the workpiece is placed between two electrodes, the foot pedal is pressed, and the upper electrode contacts and presses the workpiece. When the foot pedal is pressed further, the power contact switch is turned on, so the transformer starts to work and the secondary circuit is energized to heat the workpiece. When the foot pedal is released after welding for a certain period of time, the electrode rises, and the power is first cut off by the tension of the spring and then restored to its original state, and the single-point welding process is completed.
