WARNING
Risk of burns
The welding torches will become overheated if the coolant level is too low.
• Wear protective gloves.
• Check the coolant level at regular intervals.
NOTE
• Check the minimum coolant level of the cooling unit.
• Coolant supply = blue, coolant return = red.
• 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 purged of any air. Disconnect the
coolant return hose from the re-circulating cooling unit and hold it over a
collecting device. Close opening at the coolant return. Open it again by
repeatedly and abruptly releasing it, until the coolant is flowing
continuously and without air bubbles.
