Coolant
The coolant can be filled in the cooling system after having
connected the welding torch.
Always use a coolant approved by CLOOS! It is not allowed
to use chlorinated or mineral water because of its electrical
conductivity.
Via filler neck the coolant is filled into the storage tank. The
tank can be filled up to approx. 90%. After filling a small
expansion space should remain to take up coolant which
returns from the connection cable assemblies.
The filling level can be checked at the sight glass (indicator)
on the left side of the rear.
By opening the drain cock at the rear of the machine the
pipe lines are vented and the coolant is brought to the
pump.
The water hoses are filled when the pump runs. When using
very long cable assemblies, the resulting loss of water in the
storage tank must be replenished. Please note the maximum
coolant quantity (level)!
The cover must always be screwed down to prevent
contamination of the cooling liquid!
Water-cooled torches must always be operated with a
coolant. Otherwise an overheating or damage of the torch
may occur.
If a gas-cooled welding torch is operated on a water-cooled
welding machine, it is necessary to bridge the water circuit
by means of a hose in order to avoid that the water pump is
damaged (overheating).
Please note the following if welding machines with cooling
liquid are used:
Used coolant must be disposed of correctly as hazardous
waste in accordance with the official local regulations.
The coolant must not enter the normal waste water system!
CAUTION!
