3. MACHINE USE
3.1 Starting of 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. The control panel and wire feeder are not operational yet,
and the text ‘OFF’ is shown on the control panel display.
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.
3.2 Front panel indicators
The following indicators can be found on the front panel of the device:
• When the green 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. The fan
then starts. When the indicator turns off, the machine can be used again.
• When indicator A4 blinks, the machine has experienced 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.
