The cooling unit pumpstarts automatically when welding starts. Proceed as follows:1. Start power source.2. Check water level and input flow of the reservoir, add liquid if needed.3. If you use a water-cooled torch you can fill it with water by pressing WATER FILL buttonfor more than 2 seconds.The pump operates for 4 another minutes after welding has been finished to cool the water to thesame temperature as in the machine surrounds. This reduces the need of service.Thermal overloadThe thermal overload light is lit, the machine stops and display shows COOLER when temperaturecontrol of the machine has detected cooling water overheating. The cooling unit fan cools downthe water, and when the light goes out welding can be started again.Water flow signalDisplay shows COOLER when water flow is blocked.3.4. STORAgEThe machine must be stored in a clean and dry room. Protect the machine from rain and directsunshine in places where temperature exceeds +25 °C.
