When leaving the factory, cooling unit status is set 'ON'. If no cooling unit is connected, set the cooling unit status to 'OFF'. Depending on your panel type follow the instructions described in the graphic below. Having selected the cooling state required, reset the power source by switching off at the main on/off switch. Restart the power source and weld.
Primary circuits of the machine are protected against sudden, transient overvoltages. The machine is designed to withstand 3 x 440 V voltage continuously. Ensure that voltage is kept within this permissible limit, especially when the mains supply is provided by a combustion engine generator. If the mains has under voltage (under approx. 300 V) or overvoltage (over approx. 480 V) machine control stops operation automatically.
The fan is started for a moment when the main switch is placed into position I. The fan will start during welding as the machine heats up and it will continue running for 1 to 10 minutes after the welding has stopped.
