Operating Precautions; Turning The System On - Lincoln Electric COOLARC-45 Bedienungsanleitung

WARNING
AVOID SPILLING COOLANT INTO THE BACK CASING
OF THE UNIT.
NOTE: DO NOT ADD MORE THAN 6 LITERS OF
COOLANT INTO THE RESERVOIR.
WARNING
AT FIRST STARTING
RESERVOIR FILL CAP MUST BE REMOVED FOR A
MOMENT TO AVOID GENERATE PARTIAL VACUUM
IN COOLING SYSTEM DURING FILLING (THE PUMP
MUST BE FLOODING).
Be certain to replace the reservoir fill cap when the
reservoir is full. Operation of the COOLARC-45 cooler
without the fill cap in place can cause poor cooling
efficiency, evaporation loss of coolant, and low product
life.

FIGURE 2:
Water Hoses Connection Diagram
Water hoses connection is made with quick water fittings
(type 21KATS09MPX) which are equipped with the
automatic outflow blockade.
Before water hoses installing to the cooler, you should
check if the water hose connectors matches to the quick
water connectors placed in the connector block on the
front of the unit. You should:
•
Take INLET hose (colored or tagged blue on most
hoses) and attach it into the coolant OUT line
marked . Then take the OUTLET hose (colored
or tagged red on most hoses) and attach it into the
coolant IN line marked
WARNING
BE CERTAIN THAT NO LEAKS EXIST WHEN COOLER
IS TURNED ON. A LEAK WILL DEPLETE RESERVOIR
VOLUME, CAUSE
PERFORMANCE AND REDUCE GUN, TORCH OR
PUMP LIFE.
The following should always be observed when
operating the COOLARC-45:
•
Never operate the cooler with case off.
•
Immersion in water around electrical lines can
cause electrical shock.
•
Never place fingers into openings of cooler. Moving
parts can injure.
•
Unplug the cooler before filling the reservoir.
•
Never operate the cooler with the reservoir fill cap
off.
•
Never operate the cooler with the reservoir empty.

Operating Precautions

The following should always be observed when
operating any COOLARC-45 cooler:
•
Check the reservoir daily.
•
Keep the reservoir full especially after changing any
water lines.
•
Avoid placing the cooler near areas of extreme heat.
•
Avoid placing the cooler near a flux hopper or an
area where dust build-up is extreme.
•
Avoid kinking or putting sharp bends in any water
lines.
•
Keep all water lines clean.

Turning The System ON

After filling the reservoir and connecting the coolant
hoses to the COOLARC-45 cooler per the Installation
Sections, be certain that the power input into the unit
matches the cooler's rated input. Plug the unit into an
electrical receptacle for start-up operation.
You will be able to hear the fan running and feel air flow
out of the back of the unit when the cooler is operating.
When first starting the unit, check all of the water lines to
insure that no water leaks are present. Water leakage
causes poor welding performance, poor cooling
performance, low welding component and pump life and
potential electrical safety hazards.

Circulation of COOLARC-45
The high cooling efficiency COOLARC-45 offers a
cooler, more comfortable weld than conventional air-
cooled procedures as well as leading competitors water
cooled systems. Radiator improves heat convection with
minimal air flow restriction.
