Functional characteristics

5.3
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!
The cooling modules (pump and fan) are controlled by the welding machine only.
The welding machine automatically detects and displays a lack of coolant
(see the welding machine operating instructions).
Adding coolant
5.3.1
If the cooling system is empty or only insufficiently filled with coolant, the coolant pump is automatically
switched off after approx. one minute (protection against destruction). At the same time, the welding data
display signals the lack of coolant or low coolant level.
• Reset the coolant error, fill coolant and repeat the operation.
The unit is supplied ex works with a minimum level of coolant.
