NOTE

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.

2 Coolant supply hose
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 (1) from the re-circulating
cooling unit (2) and hold it over a collecting device.
2 Close the opening at the coolant return hose (1) 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 (2) and reconnect the coolant
return hose (1) .
NOTE
• Repeat this procedure until the coolant is drained continuously and
without air bubbles.
• Check the minimum coolant level of the cooling device.
