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 temperature is too high. When the circulation is defectless, the indicator LED is green.
Press the coolant circulation button after each time you change the welding gun.
For instructions on filling the cooler, see Filling cooler.
Connecting earth return cable
|
Keep the welding piece bonded or connected to earth to reduce the risk of injury to users or damage to electrical equipment. |
Figure: The earth return cable connector on the power source:
Attach the earth return cable clamp on the welding piece.
Ensure that the surface contact to the table is clean of metal oxide and paint and that the clamp is firmly secured.
Fill the cooler with 20-40 % coolant solution, for example, Kemppi cooling liquid.
X8 MIG Welder measures the voltage of the welding arc and the voltage loss in the interconnection cable and welding gun. After calibration, the power source calculates the arc voltage, if the voltage sensing cable is not connected.
