2.3 ASSEMBLY WITH THE WELDING POWER SOURCE
DANGER!
Lifting and positioning
Read the warnings highlighted by the following symbols in the
“General prescriptions for use”.
1.
Set the welding power source ON/OFF switch to “O” (unit de-
energized).
2.
Remove the screws from the power source cabinet.
3.
Loosen the screws of the upper brackets of the cooler and open
out the brackets slightly.
4.
Place the power source on top of the cooler.
5.
Secure the cooler brackets to the power source using the
previously removed screws.
6.
Connect the plug of the cooler power cable to the cooler power
socket on the rear panel of the welding power source.
7.
Plug the power cable plug into a mains socket outlet.
8.
Set the welding power source ON/OFF switch to “I” to switch on
the unit.
9.
Set the cooler ON/OFF switch to “I” (unit powered).
WARNING!
Periodically checking the level of the liquid in the indicator on the
side of the cooling unit.
Be careful when choosing the cooling liquid: it must not be an
electricity conductor.
Do not use polypropylene liquids because they damage the seals
and generate incrustations.
Read the warnings highlighted by the following symbols in the
“General prescriptions for use”.
