2.1.6 starting the power source
Start the power source by turning the main switch A2 on the front panel to the I position. The
standby indicator A3 turns on.
NOTE! Always turn the device on and off using the main switch, not via the mains socket.
The cooling fan is started for a moment when the main switch is turned to the ‘I’ position. The
fan turns off after a while and then restarts during welding when the machine has warmed up
sufficiently. The fan continues running even after up to 10 minutes of welding, depending on
the temperature of the machine.
2.1.7 power source indicators
The following indicators can be found on the front panel of the power source:
• When the green mains indicator A3 is on, the power source is in standby mode. This
indicator is on when the machine is connected to the mains supply with the main switch
in the ‘I’ position.
• When the yellow overheating indicator A4 is on, the machine has overheated. When the
indicator turns off, the machine can be used again.
• When indicator A4 blinks, the machine has encountered a failure. Attempt to remedy the
problem according to the instructions in Section 4, ‘Troubleshooting’. If the failure cannot
be eliminated, turn off the machine, and turn it on again. If the failure persists, write down
any fault code that may be shown on the display and contact authorised Kemppi service
agent.
