Functional characteristics
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).

All information relates to the total hose package length of the complete welding system and presents
exemplary configurations (of components of the EWM product portfolio with standard lengths). A straight
kink-free installation is to be ensured, taking into account the max. delivery height.

6.1.1.3 Adding coolant
If the cooling system is empty or only insufficiently filled with coolant, the coolant pump is auto-
matically 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.
