H2O Error!

If the pump is switched on and the coolant flow is still insufficient after 20
seconds, the acoustic alarm sounds continuously and the associated LED
flashes. The pump is switched off automatically. Please check the water circuit.
Ensure that the flow and return connections of the water-cooled TIG torch are
properly attached and the water-carrying hoses of the TIG torch are not kinked or
blocked. When longer hose packages are being used, it can take more than 20
seconds for an empty hose package to fill. In this case, please select On or Auto
mode again.
The acoustic alarm can be switched off by pressing the pushbutton.
