Electrode pressure and welding time of IF spot welding machine
The PLC control core of IF spot welding machine can effectively control the impulse and discharge process, respectively adjust the pre-pressing, discharging, forging, holding, rest time and charging voltage, which is very convenient for standard adjustment. During spot welding, the electrode pre...Read more -
Influence of welding time of IF spot welding machine on electrode pressure?
The influence of welding time of IF spot welding machine has obvious influence on the total resistance between two electrodes. With the increase of electrode pressure, R decreases significantly, but the increase of welding current is not large, which cannot affect the reduction of heat generation...Read more -
Solution for insecure welding spot of IF spot welding machine
For the reason that the welding spot of IF spot welding machine is not firm, we first look at the welding current. Since the heat generated by the resistance is proportional to the square of the current passing through, the welding current is the most important factor to generate heat. The import...Read more -
