LOCATION
This machine will operate in harsh environments.
However, it is important that simple preventative
measures are followed to assure long life and reliable
operation.
Do not place or operate this machine on a surface
with an incline greater than 15° from horizontal.
Do not use this machine for pipe thawing.
This machine must be located where there is free
circulation of clean air without restrictions for air
movement to and from the air vents. Do not cover
the machine with paper, cloth or rags when switched
on.
Dirt and dust that can be drawn into the machine
should be kept to a minimum.
This machine has a protection rating of IP23. Keep it
dry when possible and do not place it on wet ground
or in puddles.
Locate the machine away from radio controlled
machinery. Normal operation may adversely affect
the operation of nearby radio controlled machinery,
which may result in injury or equipment damage.
Read the section on electromagnetic compatibility in
this manual.
Do not operate in areas with an ambient temperature
higher than 40°C. The ambient air temperature
influences the parameters of cooling. If the ambient
temperature is higher, the cooling system will be less
effective
WARNING
Avoid placing the cooler near areas of extreme heat.
RECOMMENDED POWER SOURCE
The
COOL ARC
®
26
is designed for use with water-
cooled torches. The
COOL ARC
®
26
must be used with
a MIG welding power source that lists the
COOL ARC
®
26
as an approved accessory.
Input Supply Connection
The
COOL ARC
®
26
must be supplied by a welding
power source in accordance with installation procedure
that can be done only by qualified electrician. Installation
must be made in accordance with the appropriate
National Electrical Code and local regulations.
WARNING

The
COOL ARC
®
26
comes equipped with a flow sensor
that triggers an error code to the machine to protect the
Torch from over-heating when inadequate
coolant flow is detected through the flow sensor. The
Error Code fault (Error 0092) can indicate a possible kink
in the torch lines, damage and/or a leak in the Torch
coolant lines.
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.
