Lincoln Electric COOLERTIG 4 Bedienungsanleitung Seite 12

Preparation COOLERTIG 4 to Work

Fill the coolant reservoir.

Connect COOLERTIG 4 to power source.

Turn the power source on.
Warning: First use the cooler require the pump is
primed by coolant.

Turn power source off.

Connect the water-cooler hoses to the cooler's inlet [5]
and outlet [4] socket (Figure 6).

Turn the power source on.
Warning: The water-cooler hoses can require
bleeding.
Filling the reservoir and water lines
WARNING
Avoid contact with coolant. Wear waterproof
gloves and protective eye wear.
WARNING
Before filling the coolant reservoir, disconnect cooler's
power lead to the power source.
Warning: The cooler can be filled and used only in the
horizontal position.
Use only recommended
W000010167 (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 the cooler with less than 4l of coolant.
Operating without enough coolant can prevent full priming
of the system and may damage the pump.

Priming Pump (only first use the cooler)
and Bleeding the Cooling System

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.
At first using of the COOLERTIG 4 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.
