  I、Abnormal display handling


  Problem 1: Black screen


  - Cause analysis:


  - The device is not connected to the power supply.


  - The power fuse is blown.


  - The small transformer is faulty.


  - The power plug is loose or has poor contact.


  Solution:


  - Check and make sure the power cord is connected properly.


  - Replace a new fuse.


  - Repair or replace the small transformer.


  - Confirm that the power plug is tight and in good contact.


  Problem 2: Display confusion


  - Possible causes:


  - The software program runs abnormally.


  - The power supply voltage fluctuates or the line contact is poor.


  Countermeasures:


  - Turn off the power for at least 30 seconds and restart.


  - Stabilize the power supply voltage and check whether the power supply line is intact.


  II、Troubleshooting for welding dysfunction


  Problem 3: Unable to perform welding operation


  - Potential problem points:


  - Failure of welding sensor.


  - The switch controlling welding is damaged.


  - The control line connected to the welding machine is interrupted.


  - Improper installation of welding sensor.


  - Main controller failure.


  - Controller parameter setting error.


  Repair suggestions:


  - Replace damaged sensor or switch components.


  - Check and repair control cables.


  - Calibrate sensor position.


  - Update or reset the main controller.


  - Review and adjust controller settings.


  Problem 4: Insufficient welding strength


  - Common factors:


  - Too short welding cycle.


  - Low output current.


  - Sensor positioning deviation.


  - Insufficient welding pressure.


  - Contamination on the steel bar surface.


  - Increased resistance of the conductive loop.


  - The power grid has limited power supply capacity.


  Improvement plan:


  - Extend the welding time.


  - Increase the welding current intensity.


  - Accurately adjust the sensor position.


  - Increase the pressure during welding.


  - Clean the surface of the steel bar.


  - Eliminate bad connections in the conductive circuit.


  - Upgrade the power supply system to meet the needs.


  Problem 5: Frequent alarm triggering


  - Alarm source analysis:


  - Insufficient pressure during welding.


  - Sensor position offset.


  Preventive measures:


  - Adjust and confirm that the welding pressure is sufficient.


  - Accurately position the welding mesh sensor.


  - Through the above detailed troubleshooting process, various common problems of the steel mesh welding machine during operation can be effectively identified and solved, ensuring the efficient and stable operation of the machine, thereby improving the overall production efficiency.
