Preparing Welding System For Use - Kemppi X8 MIG Welder Operating Manual

3.2 Preparing welding system for use

Before beginning the use of the welder, switch the welder on, prepare the cooler and connect the earth return cable.
Switching on the welding system
To switch on the power source and wire feeder, turn the power source main switch to ON (I) position. When the power
source is on, the power indicator LED in the indicator panel is green.
Figure: Switching on the welding system:
The wire feeder starts to the same operation state where it was before the last shutdown. Turn the main switch to start
and shut down the welder. Do not use the mains plug as a switch.
If the welder is left unused for a longer period, detach the mains plug to disconnect it from the mains.
Switching on Control Pad
To switch on Control Pad, press and hold the power button for a few seconds.
Preparing cooler
Fill the coolant container inside the cooler with Kemppi coolant liquid. To weld, you must pump the coolant through the
system. Press the coolant circulation button in the front panel of the power source. It activates the motor, which pumps
the coolant to the hoses and to the welding gun.
When you press and hold the coolant circulation button, the pump begins to circulate the coolant. The line continues to
fill up automatically even if you release the button. Press the coolant circulation button again during the automatic
filling to interrupt the fill-up, for example, if any coupling is loose. If the line does not fill up during 1 minute after the
button has been released, the automatic filling stops and the indicator LED blinks green and red in turns.
The indicator panel also includes indicator LEDs which are yellow if the coolant level is too low or the coolant tem-
perature is too high. When the circulation is defectless, the indicator LED is green.
