    Here's what to expect:

    First, the mold should be kept at a constant temperature. Variations in mold temperature can create quality instability.

    Second, the high-frequency output should be adjusted as high as possible, and the high-frequency output time should be reduced at the same time. Because ignition is often caused by the material not being able to withstand the high temperature.

    Third, check whether the mold is parallel to the first plate.

    Fourth, the size of the mold does not match the high-frequency machine, which makes the effective power output of the machine decrease.

    Fifth, the transformer or AC contactor is in poor contact, so that the output current is a virtual current.

    Precautions: When the mold is pressed down and touches the lower die, the grounding copper sheet must be pressed against the lower fixed plate, and the round copper sheet can be slightly deformed.

    If the grounding copper sheet is not adjusted properly, the machine will not be able to work stably. When replacing the mold with different heights, the grounding copper sheet needs to be readjusted again.

    Precautions for the use of high-frequency machine and machine operation:

    Keep the working surface of the machine clean, and do not place Tianna water and other liquids to prevent dumping and damaging the internal components.

    2.When cleaning the floor, do not allow water to splash into the machine to prevent damage to the transformer due to moisture.

    3.There must be 3-5 minutes of warm-up time to turn on the power of the machine, so that the components of the machine can be used after reaching a stable state.

    4.Do not do any tapping work on the machine table to prevent damage to the vacuum tube.

    5.During operation, do not touch the red mold handle and its mold with your hands to prevent being burned by high frequency.

    6.When it is necessary to be unloaded, the red pointer of the matcher must be reset to the zero position.

    7.Remove the debris on the template in time so as not to affect the product quality.

    8.Regularly change the oil in the air oil trap to ensure the purity of the pressure air.

    9.Do not put any parts of the body and debris between the upper and lower templates, and pay attention to the safety of operation.

    10.Do not touch the live line with your hands to avoid electric shock accidents.

    11.Regularly fill the moving parts of the machine with oil or grease every month. Clean the inside of the chassis once every six months.

    Summary. Hello, there should be two situations for this, the first is that the temperature of the fusion place cannot be reached, and the fusion cannot be completed at one time.

    Hello, there should be two situations for this, the first is that the temperature of the fusion place cannot be reached, and the fusion cannot be completed at one time.

    The second is that the accuracy of the fusion is not enough, and the fusion is not right at one time.

    It should be the first reason.

    Yes. What causes the temperature to be insufficient.

    Take a look at the recommended maintenance personnel to repair it.

    It's good without joints.

    If you have a joint, you need it twice.

    I can't tell the exact reason for this.

    It could be the hardware.

    One lap, which is good, is that the joint needs twice.

    Understand. Thank you.

    You're welcome. If you are satisfied, you can give a thumbs up.

    If you have any questions, please feel free to contact me.

    The landlord is not a high frequency under the addition of a high temperature resistant yellow rubber board, the general situation is to pad a voltage insulation board, must have a smooth surface, high temperature resistant yellow rubber board, after the use of the ignition will not appear ignition, is also one of the materials that we have been favoring, to find a professional high cycle insulation board business, otherwise buy some fake and shoddy materials on the use of ignition and blistering, there is a problem is to maintain the machine.

    The material of your product may affect the heat sealing effect, TPU and other materials must be heated to complete, and the power of the machine is also a more important factor.

    It is recommended that you add some temperature to assist in welding.

    High-frequency fusion splicerCommon faults and troubleshooting

    1. There is no anode current when working.

    2. Gate resistance is broken.

    3. The yang current and gate current transfer switch is damaged.

    4. The high-voltage DC is not input to the anode of the tube.

    5. The AC contactor is damaged by electric shock, and the transformer is not energized.

    6. The high-frequency travel switch is damaged.

    7. The relay is not plugged in.

    8. When the high voltage is turned on for about ten seconds, the anode current will automatically rise slowly and appropriately reduce the gate current.

    9. The no-load anode current is large, and the output port of the resonator is heated. The capacitance of the cylindrical capacitor is small, and the gap between the aluminum plates of the capacitor is adjusted (reduced) to increase the capacitance.

    10. The no-load anode current is very large or large.

    11. Fire inside the resonator to remove dust or foreign matter.

    12. The tube-side capacitor is ignited and polished and ablated.

    13. The lower electrode plate is poorly connected with the resonator, that is, the adjustment capacitor cover is poorly connected with the aluminum sheet below the table or the two sides of the adjusting capacitor cover are poorly connected with the resonance.

    14. The conductive band drawn from the resonator is connected with the cavity or the side plate of the adjusting capacitor.

    15. The top cover of the resonator is in poor contact with the cavity, and the connection is polished with an abrasive cloth to make it have good contact after being removed.

    16. The capacitor of the tube filament bypass is broken.

    17. Gate capacitor is open.

    18. The anode current rises slowly during operation. The capacitance of the cylindrical capacitor is too large, and the gap is adjusted (increased) to reduce the capacitance.

    19. During operation, the brightness of the electron tube decreases significantly with the increase of output power, and the AC contactor cannot be firmly engaged. The inlet voltage is too low or the inlet diameter is too thin.

    20. The brightness of the tube is not enough. Poor contact between the tube and the header or aging of the tube.

    21. The AC contactor jumps randomly during operation and cannot be sucked in.

    22. The bridge high-voltage rectifier has one or two sets of breakdown.

    23. In the high-voltage DC system, the high-voltage capacitor is 300p 12kV breakdown or the line is connected to the casing, and the gate of the electron tube is connected to the casing.

    24. Short circuit between the poles of the tube. Disconnect the anode of the tube, be careful not to touch the casing, if the operation is normal, you can preliminarily determine the failure of the tube, and replace the tube with a new one for trial operation.

    25. High voltage transformer short circuit. It is manifested that there is no positive current but the AC contactor jumps randomly and cannot be engaged, and the transformer is disconnected from the high-voltage rectifier and operated, if the fault is still there, the high-voltage transformer needs to be replaced.
