CYLINDER MAY EXPLODE IF DAMAGED: Use only compressed gas cylinders containing the
correct shielding gas for the process used and properly operating regulators designed for the gas and
pressure used. Always keep cylinders in an upright position securely chained to a fixed support. Do
not move or transport gas cylinders with the protection cap removed. Do not allow the electrode,
electrode holder, work clamp or any other electrically live part to touch a gas cylinder. Gas cylinders
must be located away from areas where they may be subjected to physical damage or the welding
process including sparks and heat sources.
Installation and Operator Instructions
Read this entire section before installation or operation
of the machine.
Product Description
COOLARC-45 is the cooler for semi automatic welding
with water cooled TIG, MIG.
COOLARC-45 cooler is designed for use with all water-
cooled gun’s up to 500A, TIG and MIG torches and
guns.
The COOLARC-45 coolers bring new technology in the
areas of pump, heat exchanger and reservoir designs to
the water cooler market. These technologies allow the
COOLARC-45 coolers to be lighter in weight, lower in
energy consumption.
Warranty
Warranty for this product is 3 year after the date of
purchase. For any warranty claim, contact a certified
Lincoln service center.
Installation
FIGURE 1
Coolant INLET and OUTLET fittings (A) type
21KATS09MPX are placed at the front of the unit. The
blue fitting is marked
(supplies coolant to the welding
equipment); the red ones is marked (takes warm
coolant from the welding equipment).
The FILL CAP of the coolant reservoir is on the top of
the unit
(B). Fill Cap can be removed by twisting it off.
Air flow louvers (C): Air flow louvers secure adequate air
circulation. The side louvers allow sucking in cold air
from bottom of the unit. Hot air is removed by the front
louvers.
For convenience you can press and hold the FLOW
SENSOR OFF switch (D) and the torch button to fill the
water system on first usage
.
WARNING
INCORPORATED INTO THE COOLER IS AN
AUTOMATIC FLOW SENSOR TO DETECT LOW OR
NO COOLANT FLOW.
A LOW OR NO FLOW
CONDITION WILL CAUSE WELDING OUTPUT TO
AUTOMATICALLY STOP TO PROTECT THE TORCH.
Filling The Reservoir
Proper Coolant Addition
Acorox is recommended coolant for COOLARC-45 .
For use above freezing: Tap, distilled, deionized, mineral
water. For use below freezing: water and pure ethylene
glycol mixture (10% glycol between at 0°C and 30% at -
15°C).
WARNING
DO NOT USE PREPACKAGED WELDING INDUSTRY
COOLANTS
. These coolants may contain oil-based
substances which attack the plastic components in the
pump of the COOLARC-45 cooler and severely reduce
pump life. Once added to the cooler, the substances are
virtually impossible to purge from the water lines and
heat exchanger.
To avoid freeze damage and water leakage in shipment,
every COOLARC-45 unit is delivered empty with no
coolant in the system. To fill the unit, locate the plastic
reservoir fill cap (B).
NOTE: The unit can be filled only horizontal.
WARNING
UNPLUG THE COOLER BEFORE FILLING THE
RESERVOIR.
Filling:
Pour 4 liters at least of coolant into the reservoir.
WARNING
DO NOT START COOLER WITH COOLANT LESS
THEN 4 LITERS.
TOO LESS VOLUME OF COOLANT CAN NOT BE
ENOUGH TO FULL PRIMING OF THE SYSTEM AND
MAY DAMAGE THE PUMP.
