Applicable Systems
Power MIG
Symptoms
Flow rate is below the minimum required threshold. System operation may be degraded or halted.
Possible Causes
- Pump or blower performance degraded
- Flow path restricted by blockage or valve position
- Leak in the flow circuit reducing effective flow
Troubleshooting Steps
- Step 1: Measure actual flow rate and compare with setpoint
Flow rate below setpoint confirmed - Step 2: Inspect flow path for restrictions and valve operation
Restriction found and removed - Step 3: Check pump or blower operation and performance
Pump or blower delivering rated output
How to Reset
To reset: Clear the flow alarm after restoring adequate flow rate.
