OPERATION

See also 2.4.2. Main parts of cooling unit

The A7 Cooler cooler operation is controlled by the

microprocessor of the power supply. The cooler pump

starts to operate when the welding begins. After the

welding has stopped, the pump will operate 1 to 5 minutes

longer depending on the welding time. During this time

the liquid will cool down to the ambient temperature and

cools down the welding gun.

Check the tank liquid level regularly and add liquid, if

necessary.

If the tanks coolant liquid level runs low, welding is

stopped and an error code appears on the FastMig panel.

See troubleshooting 4.5.

The overheat signal lamp is lighting when temperature

control of the machine has detected cooling water

overheat. The ventilator cools down the machine and

when the lamp goes out welding can be started again.

The machine must be stored in a clean and dry room.

Protect the machine from rain and keep it away from

direct sunshine in places where temperature exceeds

+25° C. Check that there is free space in front of and

behind the machine for air circulation.
