Overloading the coolant pump!
The cooling unit must not be put into operation without a welding torch connected, as otherwise
the coolant pump will be destroyed due to thermal overload (the coolant cannot circulate in the
coolant circuit).
•
Connect the coolant connections for the water cooled welding torch to the cooling module.
•
If air-cooled welding torches are used, the control and supply line between the cooling module
and welding machine must be disconnected!
