9. Water flow Control / trouble
The machine has a water flow meter in the cooling circuit.
If the water pump is running, the water quantity (litre / minute) is shown in the display by
pressing the Compressed-air test key (Chap. 5-6).
If the water quantity is getting to low the Control unit cuts off the current source, the arc
ignition function of the torch trigger is now inactive.
The Errorcode ‘H20’ is flashing in the display.
The plant will be operable again as soon as the water problem is found.
Check the water level in the tank, the water connections and the torch.
To Restart, the machine must be switched ‘OFF’- and ‘ON’ again.
- ONLY use Jäckle & Ess coolant JPP (Order No. 900.020.400)
- Unsuitable coolants can cause property damage and loss of warranty.
- Do not mix with water or other coolant.
- Do not weld without cooling water! Tank must always be full.
- Pump must not run dry, not even for a short time. Deaerating the pump.

10. Stand-bye mode / fan Control system
The machine has 2 separate fans and a water pump.
To reduce the noise of the machine, the components are only used when they are
necessary. If the machine is not in use, all components are switched off. The machine is in
stand-bye mode.
Another advantage is the reduction of the pollution inside the machine.
If the torch trigger is pressed, the water pump and the fans for the water cooling are
starting to cool the torch.
At the end of the cutting, the water system is running for 1 Minute to cool all components.
After this, the cooling system is switching off.
The fan for the power unit is separately sensor controlled.
If the power unit is getting warm, the fan starts the cooling until the temperature is low
enough.
Under bad conditions it is possible, that the machine is getting to hot. In this case, the
machine switch off and the Temperature fault indicator LED (Chap. 5-4) is flashing.
With the fan running, the unit will be operable again after a few minutes.
