797.x Flow rate too low
Description
Welding machine: shielding gas on the inside and outside
The flow of the shielding gas on the inside and outside is monitored. An error is triggered if the entered switching threshold is undershot. The last measured value is displayed if an error occurs while the machine is in production mode.
The gas valve is switched on for 10 seconds when the function Gas ON is selected. Thus, the protective gas flow rate can be set without production.
Remedy
- Check the shielding gas flow. Is the gas bottle empty?
- Set the shielding gas flow manually on the inside and outside.
- Set the shielding gas on the inside and outside to the minimum flow. 0.0 l/min ==> not active.
- Shielding gas can be switched on and off manually.
- Check analog inputs according to the diagram.
