•
Orange pilot light: when it is on, it indicates that there is a lack of pressure in the cooling circuit
and welding is not allowed.
Please note that if cooling fluid doesn't circulate welding is not allowed: this may happen if there is not
enough fluid in the system, or if you are using a torch that is not water cooled.

•
Make the cooling unit connection cables go through the
cable clamps placed on the generator rear. Remove the bri-
dge between PS-PS contacts, then connect the cooling unit
safety device (pressure switch) cable to them (this cable is
easy to recognize, since it has just two wires).
•
Then, carefully connect the cooling unit power cable (three
wires cable) to the terminal board.
•
Extra care must be taken, since both 230V and 400V coo-
ling units can be connected to it.
•
Before connecting the power cable, check the cooling unit
voltage on the rating plate. After having connected the ca-
bles, tighten the cable clamps.
•
Reassemble the right top panel
•
Interconnect the wire feeder to the generator and the coo-
ling unit, following cooling fluid input and output instructions
(Fig.6A).
•
Before switching on the water cooler, check on the notch
scale that tank is filled with coolant. Fill it up with distilled
water adding ethylene antifreeze.
Important: Do NOT use the water cooler without
coolant, this may cause damages to the glands.
Use only ethylenic anti-freeze liquid, do NOT use
liquids with polypropylenic base.
•
Connect the torch to the euro connector, and torch cooling
pipes to the fast connectors placed on the cooling unit front,
following cooling fluid input and output instructions.
•
Now connect the generator to the mains and check if coo-
ling unit is working correctly.
On the cooling unit front there are the following devices:
•
Unit power switch
•
Protection fuse
