6 Putting into operation
MT/AUT/AUT RAB
Each time the device is commissioned or after each hose assembly change, the
cooling system must be ventilated as follows: Carry out the following activities:
1
Disconnect the coolant return hose
from the re-circulating
and hold it over a collecting device.
2
Close the opening at the coolant return hose
and open it again by
repeatedly and abruptly releasing it, until the coolant is flowing
continuously and without air bubbles into the collecting device.
3
Switch off the re-circulating cooling unit
and reconnect the coolant
NOTE
• Do not use any deionized or demineralized water as coolant or for
tightness or flow tests.
This may impair the service life of your welding torch.
• For liquid-cooled welding torches, we recommend using the
ABICOR BINZEL
coolant BTC-15.
