För att ansluta matningsspänningen
till COOL-ARC slå först av
svetsmaskinens kraftaggregat och
koppla ur kontakten. Ta bort
skyddet från undersidan av
kraftaggregatet, koppla in kontakten
för COOL-ARCs matningsspänning
och sätt tillbaka skyddet. Montera COOL-ARC på
kraftaggregatet med hjälp av de fyra medföljande
skruvarna. Kontrollera att COOL-ARC är säkerat
ansluten innan enheten lyftes.

Inkoppling av Svetskablar
Before connecting a water-cooled torch, disconnect all
power to the power source.
Inlopp och utlopp för kylmedlet sitter på COOL-ARCs
framsida.
Från höger till vänster:
Det första uttaget är utloppet: koppla in den
blå slangen för att förse svetsen med
kylmedel.
Det andra uttaget är inloppett: koppla in den
röda slangen för att leda tillbaka det
uppvärmda kylmedlet.
Connect the twist-mate connectors from the torch to the
power source.
Sätt inte på svetsmaskinen om COOL-ARC kylaggregat
är inkopplat samtidigt
vattenanslutningar (eller
bortkopplade från kylaggregatet. Ouppmärksamhet om
detta kan skada COOL-ARC.
Fyll tanken med rätt medel och mängd
enligt avsnittet Tekniska Specifikationer
i denna bruksanvisning.
Koppla in slangarna och kontrollera
flödet samt slangarnas färg för bästa
kylning.
Turn the Power ON to the power source.
The Cooler display will illuminate and go through

initialization. The Cooler will enter into standby if a Stick
welding mode is selected.
Press the push button on the Cooler to begin priming
procedure. The Cooler display wiil show dashed lines
moving in a circular motion.
NOTE: If E43 alarm codes are encoured, the torch has
not been properly primed. Run the priming procedure
again by pressing the Cooler push button.
The system Power source / Cooleer / Torch is now ready
for water-cooled welding applications.
Kontroller och Funktioner
This new COOL-ARC is an intelligent cooling unit
equipped with a variable speed three phase rotary pump
and an embedded microprocessor PC board which
controls the pump operation, fan operation, and the
overall functioning of the unit.
The cooler operation is enabled by the power source
and utilizes a "cool as needed" approach, so the pump
and fan speed vary based on real coolant temperature.
Furthermore, error signals and related codes are
managed by the power source.
This COOL-ARC unit manages both the coolant
temperature and pressure in order to maximize the
cooling of the torch, while using as little energy as
possible. If the coolant temperature goes above the
maximum limit 185°F (85°C) or the coolant flow is
stopped or the coolant is missing, an alarm is generated
and an error code is sent to the power source. The
power source,consequently, displays the alarm ID code
on the user interface and places the power source and
cooler in a safe condition in order to avoid any damage
being done to the cooling components or to the welding
torch. Any alarm condition must be reset by the user by
clearing the alarm code at the power source user
interface before restarting operation, otherwise; the
overall welding system is kept in a standby condition
(safety mode). If a coolant over temperature is detected,
welding is stopped and the cooler is programmed to run
at maximum speed in order to recover from the high
temperature condition as soon as possible. Welding
operation cannot be restarted before the coolant
temperature has reached a temperature value below
175°F (80°C).
The COOL-ARC is enabled only when DC TIG or AC
TIG modes are selected. The cooler does not operate
when STICK modes are selected.
Due to the "cool as needed" functionality (when the
är
coolant temperature increases passed the maximum set
point) the pump speed is modulated by coolant
temperature feedback. This keeps the cooler noise
levels to a minimum.
The pump starts operating when any TIG welding mode
has been selected and the welder output is enabled.
The pump is kept on until the coolant temperature goes
below 175°F (80°C) or for at least 3minutes after welding
has ceased if the cooler was running while welding.
The 7-segments display shows the coolant temperature
during normal operation, but also displays additional
Cooler status information.
