Handheld laser welding machines are invaluable tools in modern manufacturing, but issues like gas pressure alarms can disrupt operations. A “gas pressure insufficient” alarm indicates that the system cannot detect adequate gas pressure to operate efficiently. This guide explains the primary reasons behind this issue and provides step-by-step solutions to help users resolve it effectively.
Primary Causes of Gas Pressure Alarms
- Low Gas Pressure: The gas cylinder pressure is below the acceptable range.
- Feature Enabled Without Wiring: The gas pressure monitoring function is enabled, but the required wiring is not connected.
- Incorrect Wiring: The wiring for the pressure detection system is improperly configured, leading to false alarms.
Step-by-Step Solutions
1. Verify Gas Cylinder Pressure
Problem:
Gas pressure that is too low will trigger an alarm. Handheld laser welding machines require a specific gas pressure range to function, typically 0.1–1 MPa. Insufficient pressure will not only prevent proper operation but may also result in poor welding quality.
Solution:
- Step 1: Check the gas cylinder valve to ensure it is fully open.
- Step 2: Inspect the gas gauge to confirm whether the pressure is within the recommended range.
- Step 3: If the pressure is too low, replace the gas cylinder with a fresh one or refill the existing cylinder.
Regularly monitoring gas levels and using a properly maintained gas supply can prevent this issue from recurring.
2. Confirm the Installation and Configuration of the Pressure Detection Switch
Problem:
If the gas pressure detection feature is enabled but no pressure detection switch is installed, or if the settings are incorrect, the system will generate an alarm.
Solution:
- Step 1: Determine whether a pressure detection switch is installed in the system. If no switch is present, consider disabling the gas pressure detection feature in the system settings.
- Step 2: If a pressure switch is installed, verify its configuration. The system should be set to detect high-level signals as part of its standard operation.
- Step 3: Adjust the system’s internal settings to ensure compatibility with the pressure detection switch.
Proper installation and configuration of the pressure switch are essential for accurate pressure monitoring.
3. Correct Wiring for the Pressure Detection System
Problem:
Incorrect wiring is a frequent cause of gas pressure alarms. The pressure switch must be connected to the appropriate ports to send accurate signals to the system.
Solution:
- Step 1: Inspect the wiring of the pressure detection switch. It should be connected to the normally open port.
- Step 2: Ensure that the undervoltage alarm system is set to detect a -24V signal for proper functionality.
- Step 3: Correct any wiring errors by reconnecting the components to their respective terminals. Test the wiring to ensure proper signal transmission.
Accurate wiring is critical for the pressure monitoring system to function as intended and avoid false alarms.
