Connecting the coolant
Each time the device is commissioned or after each cable assembly change, the cooling system must be purged of any air.
Carry out the following activities:
1
Disconnect the coolant return hose from the coolant recirculator and disconnect the coolant connection from the power
source and empty the hose above the collecting device.
2
Seal the opening on the coolant return hose. Then re-open it by abruptly releasing it. Repeat this process until the coolant
flows into the collection receptacle continuously and without air bubbles.
3
Switch off the coolant recirculator and reconnect the coolant return hose.

WARNING
Risk of burns
The torch will become overheated when welding without coolant or if the coolant level is
too low.
• Wear the correct protective gloves.
• Check the coolant level at regular intervals.
NOTICE
• Ensure that the coolant supply and return hoses have been correctly installed. Coolant supply = blue, coolant return =
red
• Do not use deionized or demineralized water as coolant or for leak and flow tests.
This may shorten your welding torch’s service life.
• For liquid-cooled welding torches, we recommend using
ABICOR BINZEL
BTC coolant.
Please consult the applicable safety data sheet.
