WARNING
Risk of burns
TIG welding torches 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.
