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.
• We recommend the use of ABICOR BINZEL series BTC coolant for
liquid-cooled welding torches.
• Each time the device is commissioned or after each cable assembly
change, the cooling system must be ventilated as follows:

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.
