6 OPERATION
Glycol
The cooling unit contains poisonous glycol which must not be drunk or poured down
the drain or into the soil or water. Regularly top up the tank to a level 1 cm below the
top if water is lost during hose changes.
Avoid using glycol if the conditions are not cold enough to warrant it.
Pure water gives the b est cooling effect.
6.1 Flow monitor
Applies to OCF 2M and options.
The flow monitor is connected in series with
the thermal cut--out inside the power source.
If the water flow is restricted or stopped this
will trigger the flow monitor and prevent
further welding.

7 MAINTENANCE
Note:
All warranty undertakings given by the supplier cease to apply if the customer
attempts to rectify any faults on the machine during the warranty period.
7.1 Inspection and cleaning
The flow of air through the cooling unit carries small particles that stick to the cooling
element, especially in a dirty working environment. This can reduce cooling
performance. You should therefore clean the element regularly using compressed
air.
Replace the coolant about once a year. Refill with glycol mixture if the cooling unit is
to be used or stored in freezing conditions.
8 TROUBLESHOOTING
In case of major faults, contact your nearest ESAB authorised service workshop or
dealer.
Fault Action
Thermal cut--out lamp on power source comesonS Check cooling unit is running.
S Check that safety plug is fitted.
S If water is flowing, the flow monitor may be
faulty, counts as major fault, see above.
Pump or fan not working S Check both fuses
Pump not working S Major fault, see above.
Fan not working S Major fault, see above.
No water flow S Raise left panel.
Switch off, disconnect blue coupling, blow
through coolant hose to empty system.
Poor cooling effect S Clean cooling element with compressed air
