•
Unscrew and remove the coolant tank sealing cover.
•
Check filter sieve insert for dirt, clean if necessary and reinsert into position.
•
Top up coolant to the filter sieve insert, close sealing cover again.
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 level of coolant must never fall below the "min" mark.
If there is less coolant in the coolant tank than the minimum required you may need to vent the
coolant circuit. In this case the welding machine will automatically shut down the coolant pump
and signal an error, > see 7.6 chapter.
