If the vibrating disk is not used for a long time, it will inevitably appear damp! Especially in the spring season, the air humidity is high, and its insulation value will even decrease to zero. At this time, it should be dried to ensure that the insulation resistance and absorption ratio reach the specified value. If it is put into operation hurriedly, it is possible to insulate the vibration coil Breakdown, causing an accident.

    1. Before the operation of the AC welding machine drying method, the damp vibration plate and the terminals are connected in series, and the chassis is grounded, so that the three sets of windings can be heated and dried. To monitor the current changes during the drying process, a string can be connected Ammeter to observe whether the current reaches the rated current of the vibration plate.

    Drying the vibrating plate with an AC welding machine does not require disassembly and inspection of the vibrating plate, which reduces the workload. At the same time, the vibrating plate heats up with its own resistance when the power is turned on, so that the coil is heated evenly. The drying effect is better, but this method is only applicable Due to the light vibration of the vibration plate, it can not be used for a long time, because the current applied to the transformer of the welding machine when the AC welding machine is working is large, and it cannot be used for a long time, otherwise it may burn the welding machine.

    2. The operation wiring of the DC welding machine drying method is similar to that of AC, and the string ammeter should be a DC ammeter. It is easy to operate the damping vibration disk with DC welding machine, and it can dry large and medium-sized vibration disk and high-pressure vibration disk for a long time. In this way, when the welding machine is working for a long time or high current, its internal components will not be damaged due to long-term high current work, so it can be used for a large and medium-sized vibration plate for a long time.

It is worth noting that when using these two methods to dry, all contacts must be in good contact and fastened, and the lead wire of the welding machine must use a special wire. The cross-sectional size should meet the current carrying capacity of the welding machine output current. Pay attention to the cooling of the transformer of the welding machine, and ensure that the insulation resistance of the vibration plate cannot be less than 0.1Ω. Also pay close attention to the temperature of the vibrating disk windings and adjust the voltage and current in time.
