Fastcool 10 / 0648 – © kemppi oy2.5. PREPARING FOR OPERATIONCooling liquid is injurious! Avoid also contact with skin or eyes. In case of injury,seek for medical advice.See also 2.4.2. Main parts of cooling unit.1. Connect the mains voltage and control connectors of the cooler unit to the correspondingconnectors on the base of the power supply. The connection can be established through thebase of the power supply when the devices are separated or through the right side of theFastMig 10 cooler by removing the right side plate.2. Attach the power supply on the FastMig 10 cooler.3. Connect the cooling water hoses with the wire feed unit, follow colour markings.4. Fill the reservoir with a 40 - 20 % mixture of etanol and water, or with any other suitableantifreeze agent. The capacity of the reservoir is 3 litres.5. Switch on the power supply.6. Press and hold down the test switch until the torch hoses are filled with liquid.7. Device is ready to weld.3. OPERATION3.1. COOLER OPERATIONSee also 2.4.2. Main parts of cooling unitFastMig 10 Cooler operation is controlled by the microprocessor of the power supply. The coolerpump starts to operate when the welding begins. After the welding has stopped, the pump willoperate 1 to 5 minutes longer depending on the welding time. During this time the liquid will cooldown to the surrounding temperature. If the pump is stopped, the need for maintenance of thecooler will be reduced.Check the tank liquid level regularly and fill in liquid, if necessary.If the liquid flow is blocked, a hose is blocked or folded, or the container has ran out of liquid thewelding is stopped and error code, Err 5, appears on the FastMig panel.3.2. OvERhEAT SIGNAL LAMPThe overheat signal lamp is lighting when temperature control of the machine has detected coolingwater overheat. The ventilator cools down the machine and when the lamp goes out welding canbe started again.3.3. STORAGEThe machine must be stored in a clean and dry room. Protect the machine from rain and keep itaway from direct sunshine in places where temperature exceeds +25 °C. Check that there is freespace in front of and behind the machine for air circulation.4. MAINTENANCEWatch out for mains voltage when handling electric cables!In planning product maintenance machine utilization degree and circumstances should beconsidered. Careful use and preventive maintenance help to avoid unnecessary productiondisturbances and breaks.
