Ventilate the entire cooling system as follows when used for the first time and
after every cable assembly change:
1 Disconnect the coolant return hose (4) from the re-circulating cooling unit
and hold it over a collecting device.
2 Close the opening at the coolant return hose (4) and open it again by
repeatedly and abruptly releasing it, until the coolant is flowing
continuously and without air bubbles into the collecting device.
WARNING
Risk of burns
The
ABIROB
®
W cable assembly will become overheated if the coolant
level is too low.
• Wear protective gloves.
• Check the coolant level at regular intervals.
NOTICE
• Make sure that the coolant supply and return have been installed
properly. Coolant supply = blue, coolant return = red.
• 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.
