• 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.
After the initial filling, wait for at least one minute when the machine is switched on so
that the tube package is filled with coolant completely and without bubbles.
With frequent changes of torch and during the initial filling process, the cooling unit
tank should be topped up as necessary.
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 chapter "Rectifying faults".
