WARNING
Risk of burns
The cable assembly overheats if the coolant level is too low.
• Wear the correct 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.
Please consult the applicable safety data sheet.
