4.4 Connecting the coolant
4.5 Connecting the PP control lead
The control lead is open on the machine side. The customer has to provide the connection of a
suitable plug. If all data are provided, the machine can also be delivered ready-to-connect.
Otherwise choose a compatible plug for your power supply and solder it to the corresponding
leads according to the connection diagram.
NOTICE
• Ensure that the coolant supply and return hoses have been correctly installed. Coolant
supply = blue, coolant return = red.
• Do not use deionised or demineralised water as coolant or for leak and flow tests.
This may shorten your welding torch’s service life.
• 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.
