Welding torch connection
CAUTION
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!
