Coolant and Filling the Reservoir
WARNING
Before filling the coolant reservoir, disconnect cooler's
power lead to the power source.
WARNING
Avoid contact with coolant. Wear waterproof gloves and
protective eye wear.
Warning: The cooler can be filled and used only in the
horizontal position.
Acorox is recommended coolant for COOLARC 46 (see
"Accessories" chapter).
Do not use pre-packaged welding industry coolants.
These coolants may contain oil-based substances,
which attack the plastic components of the cooler. Once
added to the cooler, these substances are impossible to
purge from the water lines and heat exchanger.
Do not use automotive anti-freeze. These coolants will
damage the pump and block of the heat exchanger,
affecting cooling performance.
WARNING
The coolant reservoir can be filled maximum 6l coolant.
Minimum 4l of coolant has to be poured into the
reservoir.
WARNING
Never operate the cooler with the reservoir empty.
WARNING
Do not start cooler with coolant less than 4l.
Too less volume of coolant can not be enough to full
priming of the system and may damage the pump.
Priming Pump (only first use the
cooler) and Bleeding the Cooling
System
Figure 5.
Assemble the welding set.
Connect the hose with quick water connector (added
to the equipment) to the cooler's inlet and outlet
socket (Figure 5).
Fill the coolant reservoir – minimum 4l.
Undo the nut.
English
At first using of the COOLARC 46 reservoir's nut has to
be removed to avoid generate partial vacuum in cooling
system during priming pump.
Turn the power source on.
Force circulation of coolant: simultaneously press
and hold the flow sensor off switch [2] and
torch's/gun's trigger until the coolant does not
circulate the cooling system and does not return the
reservoir.
Turn the power source off.
Disconnect the hose with quick water connector.
Connect the water-cooler hoses – Figure 6.
Turn the power source on.
Force circulation of coolant: simultaneously press
and hold the flow sensor off switch [2] and
torch's/gun's trigger until the coolant does not
circulate the cooling system and does not return the
reservoir.
Tighten the nut.
After priming pump and/or bleeding the cooling system,
be sure the reservoir's nut is tightened up. Operation of
the cooler without the nut is tightened, can cause poor
cooling efficiency, evaporation loss of coolant, and low
product life.
The welding set is ready to work.
Connecting the Cooling System Hoses
The power source has to be turned off.
Connect the "outlet" hose of torch/gun
(colored or tagged red on most hoses)
into the inlet quick connect coupling [5]
located on the front panel of the cooler.
Connect the "inlet" hose of torch/gun
(colored or tagged blue on most hoses)
into the outlet quick connect coupling [4]
located on the front panel of the cooler.
Warning: The water-cooler hoses are connected into
the quick connect coupling type 21KATS09MPX (see
"Spare parts" chapter), which are equipped with
automatic outflow blockade.
Before water-cooler hoses installing to the cooler, you
should check if the water-cooler hoses connectors match
to the quick connect coupling located on the front panel
of the cooler.
