4.5 Setting the shielding gas volume
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.
• Each time the device is commissioned or after each hose assembly change, the cooling
system must be ventilated as follows: Disconnect the coolant return hose from the
recirculating cooling unit and hold it over a collecting device. Close the opening at the
coolant return hose. Open it again by repeatedly and abruptly releasing it, until the
coolant is flowing continuously and without air bubbles.
• 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.
Consult the applicable safety data sheet.
NOTICE
• The type and quantity of the shielding gas depends on the welding task and the gas
nozzle geometry.
• Make all shielding gas connections gas-tight.
• To prevent the shielding gas supply from becoming clogged by impurities, the cylinder
valve must be opened briefly, before connecting the cylinder. This will blow out any
impurities that may be present.
