Filling Cooler And Circulating Coolant; Calibrating Welding Cable - Kemppi X5 FastMig Operating Manual

3.1.1 Filling cooler and circulating coolant

Fill the cooler with pre-mixed coolant solution. The mixing ratio should be 20...50% as standard. Use only ethylene or pro-
pylene glycol mixture intended for welding cooling systems, for example Kemppi cooling liquid.
Do not add water to the pre-mixed coolant solution. Do not use automotive cooling solutions or ethanol-based mix-
tures.
1. Open the cooler cap.
2. Fill the cooler with coolant. Do not fill over the max. marking.
3. Close the cooler cap.
To circulate the coolant:
Press the coolant circulation button in the cooler front panel. It activates the motor, which pumps the coolant to the
hoses and to the welding gun.
Complete the coolant circulation operation after each time you change the welding gun.

3.1.2 Calibrating welding cable

With X5 FastMig, the welding cable resistance can be measured using the built-in cable calibration function without
additional measurement cable. This calibration function is available only in MIG operation mode.
1. Connect the earth return cable between the power source and work piece.
2. Remove the welding gun gas nozzle.
3. Connect the welding gun to the wire feeder.
4. Turn the welding equipment on.
5. On the control panel, go to settings and enable cable calibration.
