2 Fasten the air-blast hose to the air-blast and spraying unit or the air-blast
valve. Seal the connection gastight if the "Cleaning with compressed air"
option is not used.
WARNING
Risk of burns
The Welding torch system WH/WHPP will become overheated if the coolant
level is too low.
• Wear protective gloves.
• Check the coolant level at regular intervals.
NOTE
• 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.
