Lincoln Electric COOLERTIG 3 Manual De Instrucciones página 13

Priming Pump (only first use the cooler)
and Bleeding the Cooling System
Figure 7.

Assemble the welding set.

Connect the hose with quick water connector (added
to the equipment) to the cooler's inlet and outlet socket
(Figure 7).

Fill the coolant reservoir – minimum 2,5l.

Undo the nut.
WARNING
At first using of the COOLERTIG 3 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 8.

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.
WARNING
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, which automatically close
when hoses are disconnected.
Before installing the hoses to the cooler, verify that the
hose connectors match the quick connect couplings
located on the front panel of the cooler.
Avoid kinking or putting sharp bends in any water lines.
Keep all water lines clean and free of any blockage.
Keep the reservoir full especially after changing lines.
Transport
To avoid freeze damage and water leakage during
transport, the coolant has to be removed from the cooler's
reservoir.
