What does MissingRootGas mean?
The required root gas supply is either off, depleted, or not reaching the laser system at the necessary flow/pressure. This will negatively impact weld quality, especially for root passes, and may cause program interruption.
Repair Steps
- 1
Verify the root gas supply tank level and ensure the root gas valve is open.
- 2
Check the gas pressure at the laser system's input specifically for root gas.
- 3
Acknowledge the message on the robot controller HMI.
- 4
Resume or restart the program.
